The ECS Journal of Solid State Science and Technology is publishing a collection of papers on perovskite solar photovoltaic and photoelectrochemical cells.
To achieve carbon neutrality, perovskite solar photovoltaic and photoelectrochemical cells are promising technologies to catalyze the growth of solar energy deployment. As the power conversion efficiency of the laboratory-scale single-junction photovoltaic cell surpassed 25 percent, it attracted huge interest from the solar industry. Additionally, perovskites have recently emerged as promising next-generation photoelectrochemical photoelectrode materials. However, major challenges remain to be overcome before the industrialization of these promising solar technologies. The technical contents covered in this focus issue should provide important electrochemical and photophysical insights for the development of commercial perovskite photovoltaic and photoelectrochemical devices and systems.
