A new slim and flexible perovskite solar cell (PSC) has been developed with self-charged power supply for wearable devices such as smart watches.
On November 18, the research team announced that they have co-developed a slim and flexible PSC that can be bent 1000 times over while maintaining its efficiency intact. The research team consists of Jung Hyun-suk, professor of SKKU's School of Advanced Materials Science and Engineering and Berkeley Professor Lee Sang-wook.
The PSC, which takes on a crystal structural perovskite (ABX3) form combining organic and inorganic materials, is gaining attention as a solar battery due to its efficient electrical output made from visible rays. However, until now, PSCs could not be used with flexible plastic materials which are vulnerable to the heat used in the processing of solar batteries which reach up to 500 degrees Celsius.
The research team succeeded in making the solar cell without heat treatment by using an atomic layer deposition technique that produces a plasma board by adding layers of atoms on a plastic surface.
This PSC's efficiency is 12.2 percent, superior to any existing PSCs. "Making PSCs without heat treatment will earn its place as a future generation solar battery," said Prof. Jung. The research is described in detail in the journal Energy and Environmental Science published by the British Royal Society.
