Author: Source: Datetime: 2017-12-06 12:40:02
According to local media reports in Japan, for the new generation of "perovskite solar cell" solar cell materials, researchers at the Advanced Science and Technology Research Center of the University of Tokyo have achieved a high conversion efficiency of 20.5% without using rare metals such as rubidium And stable power generation. The study has realized the stability of the crystalline structure by adding more potassium elements present on Earth. Research group in the long-term durability test at the same time, facing Matsushita, Toshiba and other enterprises practical evaluation and discussion.

The so-called perovskite solar cells, is the use of a perovskite crystal structure of this material solar power generator solar cells. Compared with the current mainstream of silicon solar cells, the manufacturing process is simple, low manufacturing costs. At present, solar cells with a practical conversion efficiency of more than 20% are used, and rare metals such as rubidium and cesium are used to maintain the structural stability.
