Inverted perovskite solar cell with 22.15% efficiency, 83.92% fill factor
Chinese scientists have used daminozide as an interlayer and additive to make a perovskite solar cell with a p-i-n structure. It has the highest efficiency and highest fill factor for a polycrystalline, MAPbI 3-based inverted perovskite solar cell to date.
Squad Mobility prices solar car at $6,250
Squad Mobility will start selling its new two-passenger Squad solar electric vehicle in the US market in January. It is designed for quick trips like grocery shopping or short-distance commutes.
PV system fires potentially exacerbated by gap between solar panels, rooftops
Norwegian researchers have published a new study showing that the space between solar panels and rooftop surfaces might play a critical role in contributing to PV system fires.
Novel sodium-sulfur battery for renewables storage
A Chinese-Australian research group has created a new sodium-sulfur battery that purportedly provides four times the energy capacity of lithium-ion batteries. They say it is far cheaper to produce and offers the potential to dramatically reduce energy storage costs.
Spanish winemaker using photovoltaic wall for protection, energy
Vins Raïmat has built a 30 kW vertical solar installation as part of a 300 kW PV system at its winery in the Catalonian town of Raïmat, Spain. It protects the wine tubs from the sun while also reducing their energy consumption.
Cooling solar panels with cold steam from ultrasonic thermoelectric generators
Iranian researchers have looked at how ultrasonic thermoelectric generators could be used to lower the operating temperature of solar modules. Their new system can generate cold steam via ultrasonic piezoelectrics in a simple batch system.
Paths to commercial success for renewable energy tech
Analysts have studied lab-to-market pathways for clean energy technologies, including First Solar’s cadmium-telluride thin-film solar modules.
Trina Solar unveils 425 W all-black solar module with 21.3% efficiency
China’s Trina Solar has developed an upgraded version of its Vertex S All Black PV module, with about 30 W of additional output. It is offering the new product on the Australian market.
Selenium solar cell with 5.2% efficiency, 0.99 V open-circuit voltage
Danish researchers have built a selenium solar cell with the highest open-circuit voltage ever reported. They said that with further improvements in the optoelectronic quality of selenium, the device could reach an efficiency of up to 8%.
Finnish mine to host 75 MW/530 MWh underground pumped hydro facility
Suomen Energiavarasto Oy has secured €26.3 million ($27.5 million) from the Finnish government to build an underground pumped hydro project at a former zinc and copper mine.
