Analysis of Color and Current Density for a-Si:HThin -Film Solar Cell Employing Transparent Multilayer Electrodes

Transparent multilayer electrodes (TMEs) are employed on the front and rear sides of a transparent amorphous silicon thin-film solar cell for building-integrated photovoltaic (BIPV) windows. Using a finite-difference time-domain simulation method, the reflection colors and generated current density were analyzed for outdoor sunlight and indoor fluorescent light. Adjusting the optoelectronic controlling layer of the TME can implement various front and rear reflection colors without significant changes in generated current, which will be a useful method for BIPV windows.
