Ten breakthroughs in the inventory of flexible Energy Storage: changing the Future of Intelligent hardware(4)

"Printing" Breakthrough the difficult problem of perovskite flexible Solar cells

In January 5th 2018, at the beginning of the new year, good news came from the research field of flexible energy storage. Song Yanlin, a key laboratory of green printing at the Institute of Chemistry of the Chinese Academy of Sciences, has broken through the problem of flexible perovskite solar cells by means of "printing". A perovskite flexible solar cell with thickness and flexibility similar to that of a magazine paper has been successfully prepared, which is expected to provide a reliable power supply for flexible wearable electronics devices.

It is hard to imagine that printing, one of the four ancient inventions in China, is beginning to flourish in the new era. The team prepared honeycomb nano-scaffolds of perovskite by nano-assembly printing and built "optical resonators" inside them. These two innovations also improve the mechanical stability and photoelectric conversion of flexible perovskite solar cells.
