Lower cost, more area. Perovskite may be the answer for next-gen solar panels.
The short version:
- The prices for solar cells are dropping quickly, and the next huge drop might be due to perovskite.
- Perovskite is a naturally occurring mineral that discovered in the Ural mountains in 1839.
- Perovskite is not as efficient as silicone when used in solar cells, but it is significantly less expensive.
- Researchers have found that by adding lead to synthetic perovskite and mixing that with silicone they are able to greatly increase the area of solar panels created while maintaining an acceptable level of efficiency.
- Panasonic is looking into bringing the panel to the consumer market by the end of this year.
The original article got a little heavy on the science, but it was a good read. Weather efficiency goes up, or price comes down, or a combination of both, solar continues to grow as a viable option for renewable energy.
