Comparative Study on Temperature Coefficients of Al-BSF Solar Cells and PERC Solar Cells
2019
In next few years, PERC solar cells with higher energy conversion efficiency will become the dominant commercial cells instead of conventional Al-BSF solar cells. In this paper, a comparative study on temperature coefficients of Al-BSF solar cells, PERC solar cells and SE+PERC solar cells is carried out. From the obtained results, it is found that the (dη/dT)/η of SE+PERC solar cells is -0.3460% under STC, and the (dη/dT)/η of SE+PERC solar cells is the lowest among the three types solar cells with increasing temperature. Therefore, the PERC solar cells has better performance ratio in the field compared with Al-BSF solar cells.
