Roadmap on halide perovskite and related devices

Abstract

Since the first report on solid-state perovskite solar cells (PSCs) with ∼10% power conversion efficiency (PCE) and 500 h-stability in 2012, tremendous effort has been being devoted to develop PSCs with higher PCE, longer stability and recycling hazardous lead waste. As a result, PCE over 23% was recorded in 2018 and stability over 10 000 h was reported. Beyond photovoltaics, lead halide perovskite materials demonstrated superb properties when they were applied to flat-panel x-ray detectors and non-volatile resistive switching memory. In this review, the progress of the lead halide perovskite in photovoltaics, x-ray imaging and memristors is investigated. Pb-based PSCs and non-Pb-based PSCs are compared, where technologies of non-Pb-based PSCs are not matured for commercialization. Pb-based PSCs were found to be highly suitable for both terrestrial and space photovoltaics. Higher sensitivity under low dose rate observed from the lead halide perovskite suggests a bright future for perovskite x-ray imaging systems. Moreover, high on/off ratio and low energy consumption observed in resistive switching enables perovskite to be a promising candidate for high density memristors.

Non‐Uniform Chemical Corrosion of Metal Electrode of p–i–n Type of Perovskite Solar Cells Caused by the Diffusion of CH3NH3I

“…Among these, the p-i-n type cells have the advantages of low processing temperature, low hysteresis, [8] high performance at low operation temperature, [6] and are considered as a good candidate for space applications. [9][10][11] Over the last decade, most of the research works are focusing on improving the efficiency of the cells through material development and device structure optimization. [1,12] To realize the commercialization of perovskite solar cells, an urgent problem that needs to be solved is to improve their stability, as the operation lifetime of the perovskite solar cell is still far from satisfactory.…”

Metal Halide Perovskites for High‐Energy Radiation Detection

“…From the discussion so far it becomes evident that 3D MHPs (Figure 1) face numerous challenges related to the sensitivity and operational stability of the ensuing devices [ 110 ] with the most recent effort dedicated exclusively to the development of postdeposition treatment steps. [ 110 ] Unfortunately, most of these strategies add to the process complexity with adverse effects on the economics of manufacturing. Recently, an attempt has been made to tackle this issue by utilizing solution‐processed 1D (see Figure 1) inorganic halide perovskite CsPbI 3 crystals [ 111 ] for X‐ray detection.…”

Solar Array Technologies for Planetary Science and Astrobiology Missions

“…In addition, worldwide research on perovskite materials that can be deposited on lightweight, low cost substrates has resulted in rapidly increasing efficiencies for both single junction and multijunction structures. This technology offers the possibility of large, ultra-lightweight and lower cost space arrays in the future 23 , even with efficiencies that are generally lower than SoP solar cells.…”
