Physical chemistry of hybrid perovskite solar cells
Hybrid perovskite solar cells were first reported in 2009 by Miyasaka and co-workers (J. Am. Chem. Soc., 2009, 131, 6050) and sparked an exciting change in photovoltaics research, a field that has been growing rapidly ever since.

Strategic improvement of the long-term stability of perovskite materials and perovskite solar cells
This review provides a comprehensive overview of the recent strategies aimed at enhancing the long-term stability of perovskite materials and perovskite solar cells (PSCs). It also extensively discusses the stability problem of perovskite materials and PSCs from perspectives of experimental tests and theoretical calculations.

How to regulate energy levels and hole mobility of spiro-type hole transport materials in perovskite solar cells
meta-Substitution is more beneficial to reduce HOMO levels compared with ortho- and para-substitution, while the hole mobility can be improved by ortho-substitution.

Influence of the mixed organic cation ratio in lead iodide based perovskite on the performance of solar cells
Perovskite solar cells were fabricated using the mixed organic cation of formamidinium and methylammonium. The mixed cation having the composition MA0.6FA0.4PbI3 shows almost negligible I–V hysteresis and better photostability than pure MAPbI3 and FAPbI3.

Understanding of the formation of shallow level defects from the intrinsic defects of lead tri-halide perovskites
For the organic–inorganic hybrid perovskites, the longer Pb–halide bond distance and the smaller band gap are the key factors to determine the shallow level energy formation of the intrinsic defects.
