The fabrication of perovskite solar cells in an N-I-P structure with compact titanium dioxide blocking, mesoporous titanium dioxide scaffold, single-step perovskite and hole-transport layers deposited using the slot-die coating technique is reported. Devices on fluorine-doped tin oxide-coated glass substrates with evaporated gold top contacts and four slot-die-coated layers are demonstrated, and best cells reach stabilized power conversion efficiencies of 7%. This work demonstrates the suitability of slot-die coating for the production of layers within this perovskite solar cell stack and the potential to transfer to large area and roll-to-roll manufacturing processes.
报道了采用狭缝式涂布技术制备具有致密二氧化钛阻挡层、介孔二氧化钛支架、单步钙钛矿和空穴传输层的N-I-P结构钙钛矿太阳能电池。展示了在氟掺杂氧化锡涂层玻璃基板上制备的器件，其具有蒸发金顶接触和四层狭缝式涂布层，最佳电池的稳定功率转换效率达到7%。这项工作证明了狭缝式涂布适用于在这种钙钛矿太阳能电池堆栈中生产各层，并且具有转移到大面积和卷对卷制造工艺的潜力。
