A pressure-assisted fast crystallization strategy for perovskite solar cells
Listed in ScienceDB
The achievement of high-performance solar cell production hinges on the development of a reliable and effective approach for perovskite crystallization that is compatible with rapid and continuous processing on large substrates.
Description
In this study, we present a pressure-assisted fast crystallization technique that reduces the thermal annealing period to less than two minutes and achieves the impressive formation of micrometer-sized vertical-monolithic perovskite crystals.
The pressure-assisted technique provides confined space and pressure, where the confined space hinders the volatilization of residual solvents and enhances the Ostwald ripening effect. The presence of pressure provides internal energy for crystal growth, while the presence of solvent molecules also accelerates solute diffusion. These factors collectively contribute to the rapid growth of grains.

Our results demonstrate that this pressure-assisted fast crystallization strategy significantly enhances the power conversion efficiency (PCE) of both n-i-p and p-i-n perovskite solar cells (PSCs), achieving PCEs of 22.80% and 24.69%, respectively. The improvement in PCE can be attributed to the reduced number of grain boundaries, minimized interfacial defects, and enhanced surface crystalline quality. Importantly, this approach is universal and highly reproducible for solution-processed manufacturing methods.
We anticipate that this efficient, reliable, and reproducible technique will accelerate the commercialization of PSCs.
