Airports could generate enough solar energy to power a city: Study
www.solarenergyconnect.com

Melbourne, Australia (SPX) Apr 28, 2021 A new study has found Australia’s government-owned airports could produce enough electricity to power 136,000 homes, if they had large-scale rooftop solar systems installed. Researchers at RMIT University compared electricity generated by residential solar panels in a regional Australian city to the potential green energy production of 21 leased […]

Squeezing a rock-star material could make it stable enough for solar cells
www.solarenergyconnect.com

Stanford CA (SPX) Jan 25, 2021 Among the materials known as perovskites, one of the most exciting is a material that can convert sunlight to electricity as efficiently as today’s commercial silicon solar cells and has the potential for being much cheaper and easier to manufacture. There’s just one problem: Of the four possible atomic […]
