Аннотация:Owing hysteresis free characteristics and good reproducibility, inverted p-i-n perovskite solar cells (PSC) are gaining large interest in the photovoltaic field. In this context, the need for stable materials calls for the development of robust transporting layers compatible with the fabrication processes of the solar cell. In this study, we introduce a new precursor, tris(ethylene diamine) nickel acetate, for low temperature (280–300 1C) deposition of NiO hole transporting layer. Full characterization of the deposited NiO film layer was performed through XRD, Raman and Auger spectroscopy. We found a direct correlation between device performance and NiO thickness with maximum efficiency exceeding 15% for the thin NiO (10 nm) layer.
