Berkeley Lab researchers advance hybrid bioinorganic approach to solar-to~chemicals conversion; 50% electrical-to-chemical, 10% solar-to-chemical efficiencies

Green Car Congress

A team of researchers at the US Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have hit a new milestone in their development of a hybrid bioinorganic system for solar-to-chemical energy conversion. In the new system, solar energy is used to split the water molecule into molecular oxygen and hydrogen.

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.

3-D nanocone solar cell boosts PV conversion efficiency by nearly 80%

Green Car Congress

With the creation of a 3-D nanocone-based solar cell platform, a team led by Oak Ridge National Laboratory’s Jun Xu has boosted the light-to-power conversion efficiency of photovoltaics by nearly 80 percent. The technology substantially overcomes the problem of poor transport of charges generated by solar photons.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

One of the main impediments to harnessing solar energy is storage. Solar batteries work as a short-term solution, but not when it comes to long-term storage or to power, say, an entire city. Solar energy and oil wells might sound like an odd combination, but the principle is similar to how geothermal energy would be harnessed.

Molten carbonate electrolysis can produce a range of carbon nanomaterials, including graphene, from CO2 at high yield

Green Car Congress

In the Solar Thermal Electrochemical Process (STEP), developed by Professor Stuart Licht and his group at GWU, solar UV–visible energy is focused on a photovoltaic device that generates the electricity to drive the electrolysis, while concurrently the solar thermal energy is focused on a second system to generate heat for the electrolysis cell.

NREL sets new world efficiency record for solar hydrogen production: 16.2%

Green Car Congress

Scientists at the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) recaptured the record for highest efficiency in solar hydrogen production via a photoelectrochemical (PEC) water-splitting process. a, Solar flux incident from the right, on an immersed tandem water-splitting device where photons with hν > 1.8
