Small solar panels will soon be able to charge electric cars on the road

Researchers claim to have developed the right combination of solar panels and batteries to charge the electric vehicle with higher efficiency than ever before.

The team, which conducted the research, said that with the help of this system in the near future it will be possible to attach a small solar panel to the car, and charge it during the trip — on a Sunny day, at least.

Researchers from case Western reserve University (private research University in Cleveland, Ohio, USA) connected four solar cells using perovskite directly to the lithium battery, while receiving efficiency of 7.8%, which, in their opinion, is the most effective configuration was today.

"We found the right combination between the solar battery and the battery ... Others use polymer solar battery charging lithium batteries, but that's another efficiency," said Dai Liming (Liming Dai), the leader of the research group, adding that used a combination surpassed all other versions combine the solar components and batteries or super-capacitors.

Perovskite is one of the most promising technologies of solar cells, have appeared recently due to its ability to convert a wider spectrum of sunlight into electricity compared to silicon acake.

Crystalline material has a structure identical to the mineral of the same name, and its potential for high efficiency energy conversion and quick payback in terms of saving energy compared to traditional energy sources, have made it one of the fastest growing sectors in the field of solar energy.

Laboratory Daya has created a multi-layered solar panels, which increases their energy density, performance and stability. Testing has shown that, optionally, three layers were converted into one film perovskite.

Consistently connecting all four cells, the area of each about 0.1 inch, the researchers further increased the tension of the chain. Efficiency of energy conversion in solar cells amounted to 12.65 percent.

When the resulting material was connected for charging Li-ion battery, the size of a coin, the team has achieved conversion and storage efficiency of 7.8%, which was maintained for several cycles.

"We anticipate that in the not too distant future, this is the system you might have at home to refuel their car and, in the end, because the solar cells from perovskite can be made as a flexible film, they can be in the car," said one of the study's authors, JANTI Xiu (Xu Jiantie).

Thus, the technology is ideal for electric vehicles with traditional appearance, the outer surface which can be coated solar photovoltaic panel. published
