The world’s first building-integrated field test of a one square meter perovskite solar panel, made by Saule Technologies, has just begun on Skanska’s Spark office in Warsaw, with a projected 5 cent per kilowatt-hour levelized cost of energy, according to Saule.
When two “wonder materials” of the solar energy age combine, good things happen. That’s the takeaway from new research that leverages graphene to create a more durable, efficient — and super cheap — perovskite solar cell.
A hydrogen economy is still in the cards according to leading solar and power-to-gas researchers at Switzerland’s EPFL, Michael Graetzel and Kevin Sivula.
Switzerland and the US state Massachusetts are forging ahead with a second Innovation Days event aimed at pushing clean tech to the next level.
By Sam Stranks A new material has entered the emerging low-cost photovoltaics arena and is threatening to blow much of the existing competition away. Power conversion efficiencies (how efficiently incident sunlight is converted to electrical power) in perovskite-based solar cells have increased from a starting point of 3.8% in 2009 to a staggering … [continued]
Hydrogen fuel cells are emerging as key players in the clean energy landscape of the future, except for one problem: it takes a lot of energy to make hydrogen, and here in the US, the preferred source of that energy appears to be natural gas. That’s hardly a sustainable solution. … [continued]
A simple, single nanowire crystal is capable of super-concentrating the intensity of the sunlight that it is exposed to up to a factor of 15, researchers from the Niels Bohr Institute have discovered. The surprising discovery means that the assumed limit to solar cell efficiency, the “Shockley-Queisser Limit,” can likely … [continued]
Researchers at Ecole Polytechnique Federale de Lausanne (EPFL) have developed a device that has the potential to monitor and save the energy consumed by large data centers. Developed at the request of Credit Suisse, EPFL researchers created the Power Monitor System and Management (PMSM) to monitor and track the … [continued]
