In recent years, the technology of producing perovskite (perovskite or calcium titanate CaTiO3, a rare mineral) solar cells has achieved serious success. One of the latest achievements is the creation of hybrid cells from several layers of perovskite with high efficiency. Now, researchers at the Australian National University have developed a new technology that further enhances their effectiveness.
Batteries from the original are cheaper and easier to manufacture in comparison with silicon analogues. Australian scientists are convinced that the best solar cells will be created on the basis of these materials in due course. Perovskitnye solar batteries, created by them in 2009, had an efficiency of only 4%. In a few years, this indicator has grown to 20%.
To further increase the efficiency, the team of the University of Australia used the chemical element indium, adding it to one of the layers of perovskite panels. As a result, scientists obtained an increase in output power to 25%.
According to one of the research leaders, Dr. Tom White, using the new technology, the efficiency of solar cells can be raised up to 30%.
