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.
Mali exempts solar from VAT, import duties
The move represents a step forward in the implementation of the National Action Plan for Renewable Energy (Paner), through which the West African nation aims to install 1.42 GW of renewable energy by 2030.
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.
Solar car tarp to recharge EV batteries
French solar thin-film specialist Armor has designed a retractable automotive solar cover. It has deployed an initial prototype on a Gazelle electric car, but it said that the cover can be used on any kind of electric vehicle.
Golden PV panels for balcony solar systems
German manufacturer a2-solar has supplied 240 solar panels for the renovation of an old building in Bern, Switzerland. The modules, which are being integrated into 96 balconies, feature different transparency options and color variations.
No such thing as ‘next-generation’ modules
According to one Dutch scientist, the development of PV technology in recent decades should be seen as an evolutionary process, rather than the constant emergence of new generations of equipment.
TOPCon technology hits 23.5% in mass production
Chinese manufacturer Jolywood claims it has reached 23.5% cell efficiency on the production lines for its n-type TOPCon technology. The achievement, which has not been verified by a third party, represents a 0.3% improvement to Jolywood’s reported mass production efficiency.
Solar pump moved by fuzzy logic
Researchers in the United Arab Emirates have proposed a PV-powered irrigation system that runs on a fuzzy logic-based algorithm, with a remote-control wireless monitoring system interface.
Solaria sues Canadian Solar for alleged patent infringement on PV cell ‘shingling’ tech
The U.S. solar panel manufacturer has filed a lawsuit against Canadian Solar in the Federal District Court for the Northern District of California.
