Solution-processed perovskite thin-films: the journey from lab- to large-scale solar cells

Abstract

This review explores perovskite crystallization in scalable deposition techniques, including blade, slot-die, spray coating, and inkjet printing.

Optimization of SnO2 electron transport layer for efficient planar perovskite solar cells with very low hysteresis

“…Perovskite solar cells (PSCs) have attracted enormous interest due to their rapid progress in power conversion efficiencies (PCEs) from 3.8% 1 to 25.5%. 2 To date, most PSCs with the highest PCEs are fabricated in the n-i-p structure, using a mesoporous TiO 2 layer as the electron transporting layer (ETL), [3][4][5][6] which, however, requires a high-temperature sintering process. In addition, PSCs employing TiO 2 ETLs are potentially unstable under ultraviolet (UV) illumination 7,8 and prolonged forward bias.…”

A Modified Sequential Deposition Route for High-Performance Carbon-Based Perovskite Solar Cells under Atmosphere Condition

“…Lead halide perovskites have excellent optoelectronic properties, such as a high absorption coefficient, high carrier mobility, and long carrier recombination life. Due to these excellent properties, the PCE of perovskite solar cells (PSCs) achieved an explosive development from 3.8% to 25.7% in a few years [1][2][3][4][5][6]. Despite the advance in the PCE of PSCs, the moisture instability of the perovskite layer, under ambient conditions, is one of the most urgent problems to be resolved.…”
