According to foreign media, the honeycomb structure inspired by insect eyes, the scientist team of Stanford University discovered a key approach to the R & D of the solar cell of titanium-titanium mine, which will make the battery more durable. Perovskite solar cells are cheap and easy to manufacture than traditional silicon solar cells. This perovskite material is used for the solar cells to be in 2009.

One problem facing this material is that the salt-like crystal structure of the perovskite is very fragile compared to ordinary silicon solar cells. Most solar equipment including solar roofs are flat design. The moisture, air, heat, or even long-term sun irradiation makes solar equipment that include perovskite solar cells are easily damaged.

In order to solve this problem, Stanford University's scientist team is looking for the development inspiration from nature - or more observing the eyes of insects. Their fly's eyes consists of thousands of hexagons arranged in photometric units and is protected by a "bracket". The team decided to follow this mode and developed a honeycomb perovskite microwate, which was protected from a hexagonal bracket having a width of 0.

02 inches by a low-cost epoxy resin. The researchers found that this bracket allows the battery to be more resistant to cracks, which has little effect on the efficiency of converting solar light into electrical energy. The team also tested the ability to resist extreme conditions for honeycomb solar cells, exposed to 85oC temperature and 85% humidity, can continue to use six weeks.

The research papers have been published in "Energy and Environment Science" magazine. .
