A perspective on the recent progress in solution-processed methods for highly efficient perovskite solar cells

Abstract

Perovskite solar cells (PSCs) were developed in 2009 and have led to a number of significant improvements in clean energy technology. The power conversion efficiency (PCE) of PSCs has increased exponentially and currently stands at 22%. PSCs are transforming photovoltaic (PV) technology, outpacing many established PV technologies through their versatility and roll-to-roll manufacturing compatibility. The viability of low-temperature and solution-processed manufacturing has further improved their viability. This article provides a brief overview of the stoichiometry of perovskite materials, the engineering behind various modes of manufacturing by solution processing methods, and recommendations for future research to achieve large-scale manufacturing of high efficiency PSCs.

The Impact of a Dynamic Two‐Step Solution Process on Film Formation of Cs0.15(MA0.7FA0.3)0.85PbI3 Perovskite and Solar Cell Performance

“…These techniques have been reported to be effective in slowing down the crystallization process and inducing denser nucleation sites thereby producing dense highly crystallized perovskite films. Alternatively, sequential deposition has been demonstrated as a promising method to better control the conversion process of perovskite layer avoiding fast crystallization resulting in good film morphology with great reproducibility . Sequential process has other advantages as it allows for i) solvent incompatibility of different precursors to be resolved; ii) separate optimizations for each precursor and for each deposition step; and iii) different deposition methods to be used for each deposition step.…”

Growth, characterization, and thin film transistor application of CH3NH3PbI3 perovskite on polymeric gate dielectric layers

“…14 Perovskite materials can also be solution processed, which is particularly suitable for printed electronics. 15 Despite the appealing potential breakthrough offered by perovskite materials, the applications in TFT are still quite limited. [16][17][18][19][20] One of the key hurdles for the fabrication of TFTs is the identication of a suitable dielectric layer for the growth of perovskite crystals.…”

“…Actually, the transverse phonon easily displaces the X anion from the B-B intermediate location of the cubic structure [32,33]. The non-perovskite δ phase appears in perovskite materials such as HC(NH 2 ) 2 PbI 3 , FAPbI 3 , CsPbI 3 , and CsSnI 3 , which, unlike the β and γ phases, is caused not by B-X-B angle distortion in the α phase, but by the breaking of the B-X bond [34][35][36].…”
