Perovskite Solar Cells

One of the hottest topics in materials science in the past few years has been hybrid organic–inorganic perovskites, which have risen to stardom due to their remarkable properties in optoelectronic applications. In particular, they have revolutionized the field of photovoltaics, with spectacular achievements in power conversion efficiencies that rival silicon and other established thin-film technologies (i.e. CdTe and CIGS). With more than 2000 publications on the subject in just a few years, perovskite solar cells (PSCs) have evolved and matured quickly. First, the efficiencies are as high as is necessary for commercialization. Then, the fundamental properties of the material have been properly established. The main debate of the field on hysteresis and ferroelectricity has been debunked. Coupled with remarkable stability and rapid progress in upscaling (i.e. modules and processing), this review will provide an overview of the latest developments in this rapidly evolving field. PSCs composed of organic-metal-halide materials have made impressive progress in just a few years with maximum power conversion efficiencies (PCEs) evolving from 3.8% in 2009 to a certified 22.1% in 2016. In the past year, huge progress has been shown for different device configurations, including the classic mesoporous-infiltrated n–i–p junction and mesoporous-free “planar” configurations. The latter are low temperature-processed SnO2-based configurations, which can now yield efficiencies close to the high temperature-processed mesoporous analogues. Monolithic tandem c-Si/perovskite solar cells have shown tremendous progress, achieving high efficiencies above 25% with a potential of above 30% with further optimization. Additionally, industry friendly deposition techniques have been developed recently, bridging the gap between academic research and its industrial partners.


We are developing new concepts and designs of perovskite solar cells.

1) Our best nanostructured solar cells based on standart MAPbI3 perovskite demonstrate up to 19% efficiencies (Project leader Alexandra Furasova).

2) Our perovkite solar cells can operate also in LED regime at certain conditions (Project leader Dr. Dmitry Gets)
