Recently, researchers are studying to resolve global warming challenges. Solar energy is a non-pollution, sustainable, abundant, and clean resource to resolve the problem. In the past few years, perovskite solar cells (PSCs) have been researched as promise next-generation solar cells due to its high efficiency, high-voltage, solution processibility, and direct bandgap. To manufacture PSCs efficiently, spray coating process is used for patterning and large-area coating. In addition to enhance the high performance of PSCs, large crystal is essential since PSCs mainly decompose in grain boundaries. Therefore, we investigated to increase the perovskite crystal grain by substituting metal halide CuBr2-complex using ultrasonic spray. |
