EVALUATION OF SERIES RESISTANCE LOSSES IN THE BASE OF SINGLE AND DOUBLE JUNCTION REAR POINT CONTACT SILICON SOLAR CELLS THROUGH SIMULATION AND EXPERIMENT

摘要

Rear point contact (locally diffused) solar cells with double collecting junctions are investigated in this work. Experimental series resistance (R_s) results are presented for two different structures, the double and the single junction solar cell, while the R_s of the cells is compared with theoretical values obtained through 3D simulations. The influence of the additional collecting junction on the back surface to the cell' s series resistance and efficiency is also studied through simulation and experimental data.
