Third Generation Maxeon Solar Cell Delivers 50% Higher Efficiency

SunPower Corp., a Silicon Valley-based manufacturer of high efficiency solar cells, solar panels and solar systems, is now integrating its new third generation Maxeon solar cell into select SunPower solar panels.

The company says the new solar cells deliver an efficiency up to 50 percent higher than conventional polysilicon solar cells and are four times as efficient as thin-film. The all-back contact design of the cell leaves the front unobscured with typical silver strings and tabs, which helps make the solar cells so efficient.

The new Maxeon contact solar cell measures 160 mm in size and produces more energy per square meter when compared to conventional crystalline solar cells, according to SunPower. It also has low reverse-bias breakdown voltage to deliver better performance in shady and dusty conditions, and better temperature coefficient for increased energy harvest in hot environments.

The new Maxeon cell has just moved from the lab into commercial production, the company says.

  1. We need to protect the technology that Sun Power Corp has developed. In saying that, if we can monopolize the solar manufacturing here in the U.S. we can create jobs and more revenue streams.

  2. Lot’s of talk and not much action. I have a 20 acre farm and have been looking for a solar system that is high efficiency and low cost. To date I have not seen anyone put together a viable package. The Federal government produces piles of documents on this subject, but no guidance on how or where to go to install a system. This article is exactly the same. Sounds great, but no real product to install.

  3. David, It is not about efficiency when you have 20 acres, its is about getting the best complete install module pr watt. If you just call a few installers who deal with commercial, you will get quotes and explanation of current government incentives which apply to you if any. Prices have dropped a lot in 2012, you really can get a serious system now for half the price of what it was a few years ago
