Stanford scientists created solar cells, inspired by the eyes of insects. The new technology will help overcome the problems that limited the use of promising material called perovskite, for the development of solar panels, Stanford News writes.

Scientists used the design of solar cells, similar to microlenses in complex eyes of insects, to protect the fragile photovoltaic material - perovskite - from wear and tear under the influence of heat, moisture or mechanical stress.

Perovskites are promising, inexpensive materials that convert sunlight to electricity as efficiently as conventional solar cells based on silicon. But the problem is that the perovskites are extremely unstable and fragile. They will be short-lived, if not come up with special conditions for their use.

Most solar panels are flat, but for solar cells based on perovskites this is unacceptable. Therefore, it was decided to use a form similar to the eyes of insects - for example, flies. Her eyes are made up of hundreds of tiny segments, each of them very fragile, but protected by a frame around it. Thanks to this technology, a solar cell based on perovskite was able to withstand a temperature of 85 Celsius and a relative humidity of 85% for six weeks.
