State and prospects of solar cells based on perovskites

The paper discusses the basic problems of the current state of research on solar cells based on organic–inorganic perovskites. The timeline of the research development in this field, the structural aspects of this perovskite class, the architecture of solar cells based on them, and the core technological aspects (in particular, aspects associated with multifaceted importance of polymers) of the creation of device structures are considered. In addition to these experimental aspects, the most important theoretical problems are addressed, such as lattice energy, defect states in pure and mixed perovskites, and degradation effects associated with moisture and photoirradiation. The given references cover the entire spectrum of research problems in the field of solar cell based perovskites, since the start of these studies and to date.
