New Solar Energy Conversion Process Could Boost Efficiency

Green Car Congress

Stanford engineers have developed a process—photon-enhanced thermionic emission, PETE—that simultaneously uses the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as efficient as existing methods. (a) a) Energy diagram of the PETE process. b) One possible implementation.

Solar reactor for the two-step thermochemical production of fuels from water and carbon dioxide

Green Car Congress

Schematic of the solar reactor for the two-step, solar-driven thermochemical production of fuels. A team from Caltech, ETH Zürich and the Paul Scherrer Institute have devised a solar reactor for the two-step, solar-driven thermochemical production of fuels. They achieved solar-to-fuel efficiencies of 0.7

DOE to re-fund Joint Center for Artificial Photosynthesis with $75M for solar fuels R&D

Green Car Congress

The US Department of Energy announced $75 million in funding to renew the Joint Center for Artificial Photosynthesis ( JCAP ), a DOE Energy Innovation Hub originally established in 2010 with the goal of harnessing solar energy for the production of fuel. The research program involves eight core projects: Light Capture and Conversion.
