Printable materials for printed perovskite solar cells

Since it's introduced in 2009, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has increased from about 3% at the beginning to 24.2% at present, which is the fastest developing new generation solar cell. However, there are still some bottlenecks to be overcome for its industrialization, including both materials and fabricating technologies. In this paper, research progresses and existing problems of PSCs related materials which can be used for printing in recent years were reviewed. The characteristics, improvement and optimization of various new materials were introduced in details. Finally, the research prospects of printing large area PSCs, improving device stability and reducing fabricating costs was pointed out, which provides some suggestions for future researches on printing efficient and stable PSCs.
