On August 4, the Qingdao Municipal Science and Technology Bureau revealed that the Qingneng Institute cooperated with domestic photovoltaic companies to develop gas repair equipment with independent intellectual property rights.It has successfully completed the repair of perovskite thin films with an area of 40 cm x 60 cm, which is basically satisfactory. Industrial requirements for the preparation of core films in perovskite solar cells.

Since the “Research on High-Efficiency Organic-Inorganic Perovskite Solar Cells” jointly carried out by the Institute of Green Energy and Israel has been supported by an intergovernmental project of the Ministry of Science and Technology in 2015, it has developed a large-area perovskite thin film repair technology. Items, 2 items have been authorized, published 8 SCI papers.

Perovskite solar cells are currently the fastest growing new generation of photoelectric conversion devices. Their photoelectric conversion efficiency is close to that of silicon cells, and the cost advantage is obvious. It is considered to be one of the most likely new solar cell devices to be widely promoted.
