Fundamental physics behind high-efficient hybrid perovksite solar cells

In front of the increasing global energy demand, solar energy will be a major player in the energy market. However, a cost effective -in terms of materials and processing- solar technology is needed. Stemming from solution-processable semiconductors, a new concept based on hybrid semiconductor (methyl ammonium-lead iodide perovskite) is challenging the photovoltaic community. This nascent technology has already grown at impressive rates demonstrating power conversion efficiency beyond 22%. Behind huge research efforts, the optimization protocols have been so far driven too much by serendipitous improvements that sometimes lack of a rational understanding and scientific reproducibility.
