Perovskite solar cell (PSC) has been widely thought as a promising candidate for next generation of photovoltaics, due presumably to its excellent opto-electrical properties and low fabrication cost. However, the commercialization of PSC has been severely restricted by its instability problems; e.g., the performance of PSC devices usually deteriorates within only hundreds of hours under ambient conditions or at high temperature. Such moisture/thermal/operational instabilities have been reported to be intrinsically unstable. To resolve this problem, new materials are required to partially replace or for doping into different layers of the device to enhance their intrinsic stabilities. In addition, optimizing device architecture and developing encapsulation methods are also important.

Therefore, the current special issue will be focused on recent developments of highly efficient and stable perovskite PV, including novel materials for charge carrier transport materials (CTM), dopants, interface passivation agents, perovskite tandem cell design, encapsulation, etc. We would like to invite you to submit your original research articles and reviews to this Special Issue.
