Match-heads boost photovoltaic efficiency

Crystal growth on a nano/microscale level produces “match-head”-like, three-dimensional structures that enhance light absorption and photovoltaic efficiency. This is the first large structure grown on a nanowire tip and it creates a completely new architecture for harnessing energy.

Team of appraisers across six states find home buyers will pay premium for solar homes

Photovoltaics added value to homes in six markets, according to a new report. They engaged a team of seven appraisers from across the six states to determine the value that solar photovoltaic systems added to single-family homes using the industry-standard paired-sales valuation technique, which compares recent sales of comparable homes to estimate the premium buyers would pay for PV.

How to train your bacterium

Researchers are using the bacterium Moorella thermoacetica to perform photosynthesis and also to synthesize semiconductor nanoparticles in a hybrid artificial photosynthesis system for converting sunlight into valuable chemical products.
