报告摘要:

Solution-processed photovoltaics (PVs) have attracted increasing attention of the

scientific and industrial communities due to the light-weight, low-cost and manufacturing

flexibility of the technology since 1990s. In the past twenty years, people have made great

effort to improve the power conversion efficiency of solution-processed photovoltaics.

Recently, a promising class of photovoltaic (PV) materials, organometal halide perovskites

with a chemical formula of AMX3, has received a lot of attention due to their excellent

electronic properties, low temperature processability, and high power conversion efficiency

(PCE).

Perovskite solar cells have been improved at a rapid pace and have already reached ~

22% PCE within four years of development due to the deeper understanding on the

fundamental science of the materials and devices, such as the formation mechanisms of

perovskite materials, the correlation between microstructure and properties, and interface

engineering. While doping as the most important technique in conventional semiconductor

industry has not been systematically inspected in organometal halide perovskite materials.

Here, I’d like to introduce my ideas and current work about doping and defect chemistry in

organometal perovskite materials.
