Optimization of substrate resistivity and light intensity of concentrator back junction back contact solar cell
摘要
Abstract
The electrical properties of N-type interdigitated back contact mono-crystalline silicon solar cell used in medium and low CPV systems were studied by using TCAD semiconductor device simulation software. The influences of substrate resistivity and light intensity on IBC solar cell’s short-circuit current density, open-circuit voltage, filling factor and conversion efficiency were studied comprehensively and systematically. The research shows that the IBC solar cell’s electrical properties are affected by the substrate resistivity and light intensity significantly. When the light intensity is low (0.1 W/cm2), the IBC solar cell conversion efficiency decreases with the increase of substrate resistivity, and the optimum substrate resistivity is 0.5Ω·cm. When the light intensity is higher (0.5~5 W/cm2), the IBC solar cell conversion efficiency increases with the increase of substrate resistivity, and the optimum substrate resistivity is 3Ω·cm. When the light intensity increases further (10~50 W/cm2), the IBC solar cell conversion efficiency presents first increases and then decreases with the increase of resistivity substrate, and the optimum substrate resistivity is 2Ω·cm.关键词
