Abstract
Here we investigate the optimal finger design for low concentration thin film c-Si solar cells using 2D TCAD simulation. The Si cell studied has a 2μm absorber layer and 1μm emitter layer with 185μm finger spacing. We confirmed the TCAD model by matching 1 sun simulation to experimental data. The solar concentration studied is from 1 to 60 suns and the finger spacing is from 185μm to 1000μm. We observe that there is an optimal number of suns and finger spacing where the efficiency is maximized. Results show efficiency is maximized at 15 suns and 700μm finger spacing and with this design the efficiency increases from 14.68 % to 17.37%.
