Sažetak
Organic perovskites are quite prominent absorbers. Their performance can be further boosted when interfaced between transport layers consisting of nano-featured semiconducting materials. Ordered arrays of zincite nanoformations were prepared for the purpose of rising up the specific surface area and thereof the charge transfer, but nanofeatured zincite arrays in organic perovskite devices show only limited increase of power conversion efficiency due to considerable recombination. Methyl ammonium and formamidinium iodide perovskites show highest power conversion efficiencies in nanofeatured zincite-based devices, but still suffer from hysteresis and degradation. For the case of the photovoltaic devices without methyl ammonium iodide, one can expect better fill factors and lower rate of hysteresis. For this work we prepared ordered arrays of zincite, before spin coating organic perovskite layer without MAI on top, and closing the solar cell. We want to understand the how preparing affects the overall PSC efficiency. We monitored the cell behavior using J/V, EQE, XRD and SEM as the main methods. We can confirm the interfacing of the layers was reliable, facilitating the further development of perovskite photovoltaic devices.
