Stanford solar tandem cell shows promise for efficient solar-driven water-splitting to produce hydrogen

Green Car Congress

Researchers at Stanford University, with colleagues in China, have developed a tandem solar cell consisting of an approximately 700-nm-thick nanoporous Mo-doped bismuth vanadate (BiVO 4 ) (Mo:BiVO 4 ) layer on an engineered Si nanocone substrate. The nanocone/Mo:BiVO 4 assembly is in turn combined with a solar cell made of perovskite.

Tony Fadell: The Nest Thermostat Disrupted My Life

Cars That Think

During the day I’d work on the iPhone, then I’d come home and pore over specs for our house, choosing finishes and materials and solar panels and, eventually, tackling the HVAC system.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

It offers the solution to several significant transitions we need: moving society from burning fossil fuels to substituting renewable resource fuels such as solar, wind and biofuels; and from using fossil materials as fuel to using them for other recyclable uses. Distributed Solar and Wind with the PHEV. It is much more than that.
