A Korean research team has successfully developed a tech to produce more efficient and cheaper solar cells by synthesizing an organic-inorganic hybrid material.
A research team head by Dr. Suk Sang-il at the Korea Research Institute of Chemical Technology announced on Jan. 7 that they have succeeded in developing a method to make organic-inorganic hybrid perovskite solar cells. Those solar cells are made from an easily synthesizable organic and inorganic material. Perovskite is a material with a special structure that shows the characteristics of both non-conductors and semiconductors, along with superconductivity.
The team has successfully made solar cells with 18.4 percent efficiency using this technique. In particular, the technology can expand the wavelengths of light that are absorbed and increase the stability of its crystal structure based on the method to make a thin perovskite film, which is similar to the structure of the solar cell platform. The new solar cells are easy to manufacture, since they are made by coating low-priced chemical materials at a low temperature.
Dr. Suk said, “This technology could overcome the limits of existing crystalline silicon cells and thin-film solar cells, which are manufactured through complex processing using expensive equipment.” He added, “Our team will try hard to develop and commercialize highly-stable original and continuous process technologies in the future.”
The research findings were first published online on Jan. 7 by Nature, a scientific journal published by the Nature Publishing Group.
