introducing the project:

During night, when window shades are left open, a lot of heat from the inside is lost. This project aims to implement photovoltaic cells in the shades such that they cause the shades to open and generate electricity during the day, and automatically close the shades at night. The key feature is the dual implementation of PV cells as power sources and as light sensors. Due to this, the heat lost during the night through windows can be conserved, which in-turn reduces the heating energy costs for buildings and improves their energy efficiency.[5-6]

General review of method

The logic is to compare the desired temperature to room temperature and opens or closes the blinds based on temperature difference. Rather than sensing temperature, this could also be done in another way, by sensing the amount of voltage produced by the PV cell, thereby gauging the amount of ambient light and controlling the shades based on that.
