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.
Preventing PID at 1500 volts
Scientists in Germany have developed a “heavy duty” test to provide insight into the long term effects of potential induced degradation in PV modules. The tests go well beyond those established by IEC standards and seek to guide manufacturers and investors on the best choice of materials – encapsulants in particular – when it comes to long term PID resistance.
Chinese city bars all new solar this year
Yulin, in Shaanxi province has brought the curtain down on around 1 GW of PV projects which are under construction. It had previously been expected the city would add around 5 GW of new solar this year.
Chinese module manufacturer unveils bolt-on plan to raise capacity
A Solargiga subsidiary has handed over $2.5 million to almost double its stake in a 1.2 GW capacity module manufacturing business set up in June by investors which include the local government.
