Researchers from Lund University in Sweden and from Fudan University in China have successfully designed a new structural organization using the promising solar cell material perovskite. The study shows that solar cells increase in efficiency thanks to the material’s ability to self-organise by standing on edge.
The current research study deals with perovskite, a new and promising material in the context of solar cells. However, in its regular form, the material is very sensitive to moisture. It simply dissolves in contact with water, and even normal humidity deteriorates the material within hours or minutes. Now the researchers appear to have overcome that problem.

“We have succeeded in producing thin sheets with a water-repelling surface, making the whole construction much more stable. In addition, we have succeeded in orienting the sheets so as to obtain acceptable solar cells, with an efficiency of ten per cent”, says Tönu Pullerits, professor of chemical physics at Lund University.
