Abstract:In this project, three different thin-film, hydrogenated amorphous silicon solar cells produced by HyET Solar were characterized on their I-V performance under variable illumination intensity and different temperatures of the cell. Each solar cell has different structure than the other ones, what makes it interesting to examine how do the design choices influence the final results. The performance of each cell was described and compared with the other cells based on their most important electrical characteristics such as open-circuit voltage, short-circuit current, maximum power point, fill factor, and power conversion efficiency. The experimental results reveled that the maximum conversion efficiency achieved in AM1.5G was 5.575% with fill factor of 0.560623. It was also found that rise in cell increase in ambient temperature causes the open-circuit voltage to drop for approximately 0.09V with every +5 degrees C while the short-circuit current increased for up to 0.03V indicating that more electron-hole pairs are generated by the induced light. It was also found that the increase in light caused linear increase in short-circuit current indicating that more light particles get absorbed causing more rapid collisions with charge carriers what directly influences generation of more electron-hole pairs.
