Another vertical PV plant in the Alps
More than 1,200 solar modules will be installed on the south side of a dam 2,100 meters above sea level. The facility planned by utility EWZ is set to be ready this year.
ClearVue’s luminescent solar concentrators create clear PV windows
The lure of building integrated photovoltaics continues to attract entrepreneurs and startups.
Redox flow batteries for $66/kWh from steel industry waste
U.S. researchers claim to have added iron sulfate to anthraquinone disulfonic acid in a redox flow battery for the first time. The scientists said the combination could lead to inexpensive and more stable redox flow storage for just $54/kWh and said $66/kWh is already possible.
A wooden solar house for €1,700 per square meter
French start-up Solaire Box has raised €1.5 million to back its business supplying wooden houses complete with PV rooftops. The buildings cost €1,700-2,000/m² and feature PV modules made by French firm Systovi. The company plans add to add features such as energy storage systems and carbon-free heating.
Six-junction III–V solar cell with 47.1% efficiency
A U.S. research group has developed a new solar cell, based on six active photoactive layers, to capture light from a specific part of the solar spectrum. The scientists claim that they could potentially reach a 50% efficiency rate with the new cell.
Shine! You’re on photoluminescence camera!
Researchers in Australia and China used intensity-modulated photoluminescence to map the series resistance of perovskite solar cells with a technique which could further understanding of the causes of instability issues in such devices.
Australian researchers enhance clean hydrogen electrolysis
Griffith University scientists have unlocked a catalytic process to enhance the breakdown of water into hydrogen and oxygen and bring Australia a step nearer clean, efficient hydrogen fuel.
New process for kesterite solar cells with 10% efficiency
German scientists have developed a new process for the formation of a phase pure kesterite Cu2ZnSnSe4 (CZTSe), which they claim can improve the material homogeneity and suppress the well-known issue of tin losses. The new technique is based on stacked elemental and alloyed precursors with a Zn/Cu-Sn/Zn precursor structure.
Fraunhofer ISE tests vehicle-integrated PV in commercial trucks
Two Fraunhofer institutes and four industrial players are working together to develop a concept that will facilitate the use of vehicle-integrated solar modules in electric vehicles and trucks. The three-year “Lade PV” project will also focus on PV components and manufacturing processes.
Using ultrasonic irradiation to separate backsheets in PV waste
Chinese researchers have used an industrial-grade, 720 W ultrasonic cleaner – with a frequency rating of 28 Khz and 1,000 W of heating power – to separate backsheets from end-of-life PV modules. They’ve concluded that an ultrasonic power of 720 W is ideal for the separation process.
