Abstract

While a-Si:H tandem solar cells deposited on textured TCO substrates have already shown high efficiency and good stability [1], the light absorption profile in such cells is still one of the important quantities to know. An accurate absorption profile is required when we do solar cell analysis, design, and optimization, or when we do computer simulations.

With the computer program GENPRO2D [2] which was developed in our laboratory, and was based on the incoherent Multi-rough-interfaces (scattering) Model, we are able to calculate the light absorption profile in a tandem a-Si:H solar cell for different light spectra and different light incident angles, provided that the scattering of light at every interface in the cell is known. In this paper, we will present our calculated results with comparison to the measured results of a real tandem cell.
