Design of perovskite ink for scalable solution process

초록

Perovskite solar cell (PSC) is currently considered as one of the most promising photovoltaic technologies for the next generation, which strongly demands the development of scalable process for PSC manufacturing. When scaling up a state-of-the-art solution process for perovskite to a large area, a comparably poor film quality generally results from the perovskite ink flow particularly with nonvolatile solvent. Therefore, the design of perovskite ink inducing a high film quality in scalable process, as well as allowing a wide window for coating speed, is the most important for scalable manufacturing to assure industrial benefits with low-energy consumption and high throughput. In this review, the progress of perovskite ink for scalable process has been thoroughly understood closely relating to the nucleation and crystal growth kinetics, where the respective roles of solvents are distinguished with their limitation.
