Engineering a better solar cell: UW research pinpoints defects in

One of the fastest-growing areas of solar energy research is with materials called perovskites. These promising light harvesters could revolutionize the solar and electronics industries because they show potential to convert sunlight into electricity more efficiently and less expensively than todays silicon-based semiconductors. These superefficient crystal structures have taken the scientific community by storm in the past few years because they can be processed very inexpensively and can be us...

Batteries to store solar energy could presage independence from

Pushing the solar envelopeWhile Tesla and SolarCity are among the biggest and best bankrolled players in solar batteries, others are dabbling in the technology. A Tustin company, EGen, has designed a battery "brain" to control the flow of electricity between solar panels or other sources and batteries. The system consists of two mobile black utility boxes, one packed with batteries bought wholesale from a supplier, the other filled with electronic equipment to manage the electricity flow. EGen f...
