As a new member of thin-film solar cells, the perovskite solar cells have inspired a new research hot in new photoelectric materials and devices, and have given a new energy to the photovoltaic science. Currently, various device structures, including mesoporous and planar, with and without hole transport material have been developed.
Meanwhile, the stability of TPSCs is significantly improved, and the stabilized power output time is up to 1000 h. Therefore, tin perovskite is emerging as a new generation of low-cost thin-film photovoltaic technology.
Advancements in perovskite materials have significantly enhanced smart window technologies and solar cells. The thermochromic properties and precise structural manipulation of perovskite films improve both efficiency and aesthetic versatility. These innovations promise further advancements and broader application in perovskite-based technologies.
Although the quality of the ETL and HTL interfaces with the perovskite thin-film is important, the quality of the perovskite thin-film is also critical to achieving high-performance PSCs.
The two representative perovskite-based PSCs fabricated via this method achieve a great enhancement in comparison with the control devices, and a power conversion efficiency (PCE) of 20.26% for a 12-square-centimeter perovskite solar module (PSM) is achieved as well.
In the last decade, the power conversion efficiency (PCE) of solution-processed perovskite solar cells (PSCs) in the lab-scale has reached an incredible level of 25.5%. Generally, PSCs are composed of a stack consisting of a perovskite thin-film sandwiched between an electron transporting layer (ETL) and a hole transporting layer (HTL).
