Spectrally selective intermediate reflectors for tandem thin-film silicon solar cells

, 2022
Thin-film silicon tandem solar cells consist of an amorphous silicon top cell and a microcrystalline silicon bottom cell stacked in series. In order to match the photocurrents of the top cell and the bottom cell, a proper photon management is essential ...

Modelling an optimised thin film solar cell [PDF]

European Journal of Physics, 2019
Abstract A phenomenological model has been developed to simulate the efficiency of thin film solar cells. The model uses key equations for p-n heterojunctions and includes radiative recombination, Auger recombination, Shockley–Read–Hall recombination and surface recombination losses.
