Development of High-Efficiency PERC Solar Cells Using Atlas Silvaco

This paper presents the results of an investigation of Passivated Emitter Rear Cell (PERC) solar cell technology and the current understanding of the fundamental device physics. The research work has been focused on the influence of the bulk lifetime, the incident angle of the solar radiation, and temperature dependence on electrical properties of the considered PERC solar cell by using TCAD-ATLAS Silvaco. Also, this paper shows the best results obtained recently and some guidelines to improve still more the efficiency of the devices. The optimization at 300 K led to the following results J sc = 41.70 mA/cm 2 , V oc = 0.727 V, FF = 80.53 %, P max = 244.439 W/m − 2 , and η = 24.44 % which are close with those found in different research works. This technology provides a better electrical control over the cell and thus leads to valuable improvements in device performance.
