A HEURISTIC PROPOSITION OF EFFICIENT COPPER-ELECTRODEPOSITED P-TYPE THIN FILM FOR CZTS SOLAR CELL
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
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.
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.
A Comparative Study Between Potentiostat Electro-deposited Cuprous Oxide and Cupric Oxide Thin films for Photovoltaic Use
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.
