    摘要： 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.

    摘要： The present disclosure relates to a device that includes a first metal oxide layer having a first thickness, a second metal oxide layer having a second thickness, and a base layer having a third thickness, where the first metal oxide layer is positioned between the base layer and the second metal oxide layer, at least one of the base layer and/or the first metal oxide layer includes a carbon-containing material, and at least one of a carbon concentration gradient and/or an oxygen concentration gradient is present across at least one of a portion of the first thickness and/or a portion of the third thickness. In some embodiments of the present disclosure, the first metal oxide layer may be permeable to an oxygen-containing compound. In some embodiments of the present disclosure, the oxygen-containing compound may include at least one of O3, N2O, and/or H2O2.
