Doping of perovskite semiconductors1and passivation of their grain boundaries2remain challenging but essential for advancing high-efficiency perovskite solar cells. Particularly, it is crucial to build perovskite/indium tin oxide (ITO) Schottky contact based inverted devices without predepositing a layer ...
High-quality defect passivation at perovskite/charge extraction layer heterojunctions in perovskite solar cells is critical to solar device operation. Here we report a ‘physical’ passivation method by producing fixed charges with aluminium oxide (negat
Photovoltaic conversion efficiency (PCE) acquired in perovskite solar cells (PSCs) is currently competitive with that of other commercial solar cells. Despite profound progress in PSCs in the last few years, achieving long term stability is considered as a prime hindrance for the commercialization ...
2.2. Fabrication of inverted perovskite solar cell (IPSC) The IPSCs were manufactured in a glovebox under a N2 atmosphere and controlled humidity. ITO/NiOxIn was used as substrate to deposit the perovskite (PVK) layer by spin coating. A solution containing 1.2 mmol of PbI2 (99.9985 %, Alfa...
