Organometal Halide Perovskites for Transformative Photovoltaics

摘要

Organometal halide perovskite-based solar cells have recently emerged as a transformative photovoltaic (PV) technology. Two important journals, Science(DOI:10.1126/science.342.6165.1438-b) and Nature, both highlighted perovskite photovoltaics as one of the major scientific breakthroughs of the year 2013. Power conversion efficiency attained with the hybrid organic-inorganic perovskite CH_3NH_3PbI_3 has now exceeded 15%, making it competitive with thin-film PV technology. Decades-long basic research on dye-sensitized solar cells and quantum dot solar cells has now led to the development of perovskite PVs. The most attractive aspects of this technology are the simplicity of photoactive layer synthesis and application using benchtop approaches at temperatures less than 100 ℃. A renewed enthusiasm has arisen among scientists in the field to continue developing economically viable next-generation PV technology. Recently, Perspective articles that highlight the evolution of perovskite PVs have identified areas of future growth for achieving efficiencies surpassing 20%. In this ACS Selects issue we present selected recent articles that focus on new methods and physical insights into the operation of organometal halide perovskite solar cells.
