Samenvatting:
The combination of a semi-transparent, wide band gap perovskite solar cell (ST PSC) with a crystalline silicon (c-Si) bottom cell in a tandem configuration is considered a promising approach to enhance solar cell efficiencies over the current single junction c-Si cell efficiencies. In this study, we use a simple model based on experimental EQEs and IV-parameters, to predict the 4-terminal tandem efficiency of advanced industrial c-Si cells of different architectures, combined with an experimental 15% ST PSC with a 1.55eV band gap. In addition, we use this model to study the expected effect of the variation of the band gap of the perovskite absorber on the 4-terminal efficiency which results in a positive outlook towards > 25% tandem efficiencies. Furthermore, we demonstrate an experimental 4-terminal tandem efficiency of 24.1% with a MWT-HIT bottom cell.
