Planar perovskite solar cell segment is expected to hold the largest market share during the forecast period

Planar perovskite solar cell has a p–i–n structure that uses both hole-transport layers (HTL) and electron-transport layers (ETL) to collect photogenerated holes and electrons to achieve high performance, wherein a high temperature-processed compact and mesoporous titanium dioxide is usually required. The planar structure can be considered an evolution of the mesoporous structure. The simple structure has attracted researchers working on thin-film PV cells. When the planar structure was demonstrated successfully for the first time, it only had an efficiency of 4% due to the inferior film quality and inadequate absorption of the perovskite film. The efficiency of planar perovskite solar cells has been increasing continuously with new developments, and the currently highest efficiency is around 19%.
