'''A HEURISTIC PROPOSITION OF EFFICIENT COPPER-ELECTRODEPOSITED P-TYPE THIN FILM FOR CZTS SOLAR CELL'''


Sunrise College, Dhaka
ABSTRACT: This paper represents a copper deposition on copper substrate using potentiostatic method. Here, deposited copper is p-type thin film where the solution can be of various salts such as Na2SO4.10H2O, NaHCO3, and KNO3. For this research, the chosen solution was CuSO4.5H2O is used. P-type copper is deposited in different parameters which were changed several times to get good quality deposition on Cu cathode. The changeable parameters that have been introduced in this paper are temperature control by heating, time, potential difference, concentration of CuSO4 solution. The parameters that has been taken as constant are current density, frequency etc. From this deposited copper substrate, the morphological operations that have been done are SEM, EDS, X-ray diffraction (XRD), UV-Vis spectrometry. For these lab works chosen samples concentration was 0.2M CuSO4, temperature was 65 degree Celsius. Potential was -0.55V where time was 40 minutes. Different types of microstructures and graphs were observed in results of these lab works. With the help of these results, the photo-chemical behavior of the deposited p-type copper film has been observed which can be used in developing more efficient solar cells with photovoltaic effects.

'''EVALUATION OF TENSILE STRENGTH OF ENVIRONMENT FRIENDLY JUTE FIBER REINFORCED POLYPROPYLENE'''


I have always dreamt of being a researcher and also to add doctorate with my name. From my childhood, I heard that to be a researcher, I have to study a lot and do something great using that knowledge. Now I have a dream of writing a lot of publications like journal papers, conference papers according to my research work. I want to get Ph.D. degree to gather knowledge and practical experiences and build a career as a researcher. In future, I want to continue my research in my homeland and also want to become a teacher for spreading my knowledge among the students.  
Abstract: Natural fiber (such as flax, hemp, jute, kenaf, etc.) reinforced polymer resin composites are biodegradable composites as they are using fibers from renewable sources. It is also better than synthetic fibers (such as glass, carbon, ceramic fibers, etc.) in a sense of environmental cause. In this research work, jute fiber reinforced polypropylene matrix composites have been developed using hot compression molding technique. Various process parameters are used such as fiber condition (untreated and alkali treated), fiber sizes (1, 2 and 4 mm) and percentages (5%, 10% and 15% by weight) in this research work. Tensile test and optical microscopy are used for characterization. Effect of tensile strength has a linear relation with fiber size and fiber percentage but after a certain size and percentage, the tensile strength shows an inverse relation with the fiber length and fiber percentage. There is no significant change has been observed for treated and untreated jute fiber reinforcement.




I am a graduate of Materials and Metallurgical Engineering from Bangladesh University of Engineering and Technology, BUET- the highest ranked university in Bangladesh. I was not a student who only memorizes the question-answers. Moreover, I always tried to understand the concept and meaning of the engineering topics. However, I could not get good results. In my early semesters, I tried a lot but failed to have a good CGPA. Consequently, I chose to do some research works. At first, I worked on tensile properties of jute fiber-polypropylene composites. Jute fiber was both treated and untreated. Treated jute fiber was treated with 20% NaOH. Tensile strength was measured in various weights and lengths of fiber. In foundry lab, the mixture was placed on a mold of 180◦C and load was 50 KN. Metallographic views were observed and tensile properties among different fiber lengths and weights were plotted in graphs. On this topic, a paper is submitted in IEEE R10-HTC 2017, Dhaka, Bangladesh. [[http://r10htc2017.com/ieee-ihtpc]]
'''A CHEAP WAY TO DEVELOP ABSORBER LAYER OF SOLAR CELL USING CUO THIN FILM'''


Abstract: This paper illustrates a proposition of developing a ptype absorber layer of copper oxide thin film by electro deposition. Potentiostatic method of electro deposition was used to make this cheap layer. Generally, crystalline silicon doped with trivalent elements, is used to make this p-type layer. Instead of using crystalline silicon CuO is used here. As the cost of copper is less than silicon, total cost is reduced so far. This CuO thin film can be developed in many ways like sputtering, physical vapor deposition (PVD, Chemical vapor deposition (CVD) etc. Among them electrolysis using three electrodes system is the most cost efficient. Here, deposited copper oxide makes p-type thin film where the solution can be of various salts such as Na2SO4.10H2O, NaHCO3, and KNO3. For this research, the chosen solution was CuSO4.5H2O is used. Four different parameters were altered several times to get good quality deposition. The changeable parameters are temperature control by heating, time, potential difference, concentration of CuSO4 solution. The parameters that have been taken as constant are current density, frequency, magnetic field etc. Clean and rinsed copper plate is used as substrate which is arranged as cathode. From this deposited copper substrate, the morphological operations that have been done are SEM, X-ray diffraction (XRD), UV-Vis spectrometry. For these lab works chosen samples concentration was 0.2M CuSO4, temperature was 60◦C. Potential was -0.5V where time was 40 minutes. From the results of characterization experiment, band gap was measured to compare the designed work with the conventional with the help of market research. Different types of microstructures and graphs were observed in results of these lab works. The photolytic behavior of the deposited CuO film has been tested which can be used as absorber layer of cost efficient solar cells with photovoltaic effects.


In my graduating year thesis work, I wanted to work on energy related work. In addition, my thesis supervisor Dr. Moniruzzaman suggested me to work on renewable energy. Likewise, I chose to make a p-type thin film of CZTS cell for solar uses. Different variables were chosen as bath composition, temperature, time, pH. Cuprous oxide (Cu2O) was deposited on the substrate. The characterization tests were done such as SEM (scanning electron microscopy), XRD (X-ray diffraction), EDS, UV-Vis spectrometry. In addition, coating thickness was also measured for each sample. From the EDS report, total Cu is 80-90% and oxygen is 10-20% which assures the Cu2O deposition. This cuprous oxide is the part of p-type CZTS thin film. From the coating thickness data reports, there were some relations found among coating thickness, potential differences, temperatures, pH values. Like this, I had planned to make another coating of zinc (Zn) on it, then tin (Sn) deposition on that. To form a deposition of sulfur (S), annealing would be done in H2S atmosphere. A conference paper about this work was published in “ECCE-2017” IEEE conference ([http://ieeexplore.ieee.org/document/7912887/?section=abstract]).


'''A Comparative Study Between Potentiostat Electro-deposited Cuprous Oxide and Cupric Oxide Thin films for Photovoltaic Use'''


Due to the busy schedule in laboratories and characterization testing machines like SEM, TEM; I could not go for further research on CZTS. But I hope to finish this someday. In this way, I had finished my compulsory thesis work for my undergrad level, six months before my graduation. In these six months, I developed another p-type thin film for solar application which is cheaper than the conventional Si solar cells. As my country is a developing country, the government cannot give electricity to the village people and because of a high cost of solar cell they cannot buy solar panels. As a result, 80 % of my countrymen remain without electricity. So, I tried to make something cheaper. According to the costing of the process, I came to know electro deposition setup is cheaper. Some research papers about the fabrication of solar cells help me to know that costing in developing p-type part of a solar cell is the major expenditure. From the market research, it is found that Cu metal is cheaper than conventional polycrystalline material. So, I chose to deposit cupric oxide CuO thin layer on the substrate. A limited thickness range of cupric oxide was maintained in all samples. Because increased thickness causes an increment in cost. Compositions of copper sulfate solution, temperature, time, voltage differences were altered. Another important property is hardness because thin film must have a sufficient hardness for preparation of solar cell. After preparations of all samples, I went to Dhaka University for SEM, XRD, UV-Vis spectrometry test. These characterization reports show the presence of cupric oxide at a certain thickness and hardness value (HRC scale) and also the measured band gap was -0.8eV. Another conference paper on this topic is now submitted on ICAEE-2017- IEEE conference. [[http://icaee.net/]]
ABSTRACT: To withstand in the rising demand for energy while fuel and chemical energy are becoming rare, the development in the production of solar energy has become a necessity. There is a variety of solar cells, among them thin film photovoltaic is more popular because of its low-cost production and good efficiency. Nowadays, copper or copper oxide has become popular to make thin film layers; such as CZTS, CIGS, CIS etc. Unfortunately, the efficiency of these thin films is less than 30%. In order to obtain better efficacy, an investigation of the layers of thin films is needed. So, this research particularly targets to reach at a point to discuss the properties of copper and its oxides. In case of making the thin film layers, potentiostat electro-deposition was the chosen method where bath composition of CuSO4.5H2O, temperature, time, potential difference were the variable parameters. The best-deposited layers were obtained in 0.2 M concentration, 40 minutes, -0.5 V potential difference and 65◦C. Hence, physical properties like thickness and hardness, and characterization properties like X-ray diffractometry (XRD), scanning electron microscopy (SEM), UV-Vis spectrometry are observed to compare cupric oxide (CuO) and cuprous oxide (Cu2O) thin films. CuO thin film shows better stability and rigidity than the Cu2O thin film. But the thin film layer of cuprous oxide illustrates good homogeneity and nodular form. From the above-mentioned test data, band gap has been measured for each deposited film and the CuO thin film layer is raked out having a better band energy gap than the Cu2O thin film layer.




I have an intense attraction to work in the field of electro chemical thin film deposition, development of the solar cell, magnetic material, Li batteries, and nanomaterial. I love work in the laboratories; an invention of new thing aspires me each and every time.

Nowadays, copper or copper oxide has become popular to make thin film layers; such as CZTS, CIGS, CIS etc. Unfortunately, the efficiency of these thin films is less than 30%. In order to obtain better efficacy, an investigation of the layers of thin films is needed. So, this research particularly targets to reach at a point to discuss the properties of copper and its oxides. In case of making the thin film layers, potentiostat electro-deposition was the chosen method where bath composition of CuSO4.5H2O, temperature, time, potential difference were the variable parameters. The best-deposited layers were obtained in 0.2 M concentration, 40 minutes, -0.5 V potential difference and 65◦C. Hence, physical properties like thickness and hardness, and characterization properties like X-ray diffractometry (XRD), scanning electron microscopy (SEM), UV-Vis spectrometry are observed to compare cupric oxide (CuO) and cuprous oxide (Cu2O) thin films. CuO thin film shows better stability and rigidity than the Cu2O thin film. But the thin film layer of cuprous oxide illustrates good homogeneity and nodular form. From the above-mentioned test data, band gap has been measured for each deposited film and the CuO thin film layer is raked out having a better band energy gap than the Cu2O thin film layer.
