Abstract
A three-tandem (3T) perovskite/silicon (PVT)-based tandem solar cell (TSC) includes an antireflection coating (ARC), a first transparent conductive oxide layer (TCO), a hole transport layer (HTL), a perovskite (PVT) layer, a second transparent conductive oxide layer (TCO), an electron transport layer (ETL), a plurality of buried contacts, a p-type Si layer, a p-type wafer-based homo-junction silicon solar cell, a n+ silicon layer, a back contact layer. The solar cell further includes a top sub-cell, a bottom sub-cell and a middle contact-based tandem. The top sub-cell includes the PVT layer. The bottom sub-cell includes the silicon solar cell. The middle contact-based tandem includes the second TCO layer to be used as the middle contact-based tandem, as well as a recombination layer for current collection. Further, a conduction and a valence band edge are employed at a front surface of the ETL.
