Kalyon PV has provided our laboratory with fundamental photovoltaic cell components — ingots, wafers, and cells — to be used in solar energy research. These materials are expected to contribute significantly to both the instruction of undergraduate students on the stages of solar panel production and the implementation of various experiments. We extend our sincere gratitude for their valuable support.
The solar cell production process begins with the processing of the silicon element, which is extracted from sand, through various methods to form a cylindrical ingot weighing approximately 400 kilograms and measuring 4 meters in length. In the second stage, the obtained ingot is sliced using wire saws with a thickness of 55 microns, producing square-shaped wafers with a thickness of 170 microns. In the final stage, the wafers undergo more than 30 chemical and physical semiconductor processes, resulting in the production of photovoltaic solar cells. At this stage, the front surface of the cell captures direct solar radiation, while the back surface utilizes reflected sunlight to generate electricity.
