Abstract

For a thin film solar cell, proper light trapping is commonly requested for the purpose of increasing the absorbing efficiency in the silicon absorbing layer. This study aims to suggest a design method for a thin film solar cell using topology optimization so that the overall efficiency increases in a specified wavelength range from 700 nm to 800 nm. For the efficient energy translation, extending the wave-path length and raising the efficiency are inevitable. The bottom transparent conducting oxide (TCO) layer shape is designed so that the propagating wave reflects on the surface and it satisfies the total internal reflection condition at the top TCO layer.
