Default Re: Universal Renewable Energy: Suitable Substitute for Morning Sex?

UCLA has achieved 2 new records in PV efficiency in less than a year. The increase in efficiency between the two records is ~ 20%. They merged visible light and IR PV into a single unit. :awesome: p. awesome.

Engineers create tandem polymer solar cells that set record for energy-conversion

"We have been doing research in tandem solar cells for a much shorter length of time than in the single-junction devices," said Gang Li, a member of the research faculty at UCLA Engineering and a co-author of the Nature Photonics paper. "For us to achieve such success in improving the efficiency in this short time period truly demonstrates the great potential of tandem solar cell technology."
"Everything is done by a very low-cost wet-coating process," Yang said. "As this process is compatible with current manufacturing, I anticipate this technology will become commercially viable in the near future."
