Halide perovskites are found to exhibit strain patterns over large areas, which influences the lifetimes of charge carriers.
Abstract There has been considerable progress over the last decade in development of perovskite solar cells (PSCs), with reported performances now surpassing 25.2% power conversion efficiency. Both long‐term stability and component costs PSCs remain to be addressed by research community, using hole transporting materials (HTMs) such as 2,2′,7,7′‐tetrakis( N , ′‐di‐pmethoxyphenylamino)‐9,9′‐spirbiuorene(Spiro‐OMeTAD) poly[bis(4‐phenyl)(2,4,6‐trimethylphenyl)amine] (PTAA). HTMs are essential...
Abstract In the past decade, perovskite solar cell (PSC) has attracted tremendous attention thanks to substantial efforts in improving power conversion efficiency from 3.8% 25.5% for single‐junction devices and even perovskite‐silicon tandems have reached 29.15%. This is a result of improvement composition, solvent, interface, dimensionality engineering. Furthermore, long‐term stability PSCs also been significantly improved. Such rapid developments made competitive candidate next‐generation...

Titanium dioxide nanocrystals are an important commercial product used primarily in white pigments and abrasives, however, more recently the anatase form of TiO2 has become a major component electrochemical photoelectrochemical devices. An property titanium for electrical applications is degree crystallinity. Numerous preparation methods exist production highly crystalline particles. The majority these processes require long reaction times, high pressures temperatures (450–1400 °C)....
