building-integrated PV

Scientists at South Korea’s Daegu Gyeongbuk Institute of Science and Technology have set a new efficiency record of 11.4% for a cell based on a copper zinc tin sulfide thin film applied to a flexible substrate.

Researchers at the University of Warwick in the U.K. have made a discovery that could lead to new designs for organic PV devices. Their findings could open up a new range of materials for the electrode layer and bring low cost, flexible organic PV devices a step closer commercial reality, say the academics.

The heavily-indebted Chinese BIPV manufacturer has warned the petition issued by the German lender to recover a disputed $6.27 million debt could threaten the survival of the business as it would halt a planned bail-out by Beijing.

The U.S. National Renewable Energy Laboratory reports further progress in bringing down the cost of III-V solar cells. Scientists have refined their ‘brand new, 50-year-old’ D-HVPE technology to speed up the production rate for gallium arsenide solar cells by a factor of more than 20. The development is a potential step toward making incredibly efficient solar cells cost effective for everyday purposes.

Copper indium gallium selenide thin film technology is on the fly as conversion efficiency closes in on that of crystalline silicon. The technology can be integrated neatly onto facades of otherwise energy intensive commercial buildings. The potential is huge even if the conversion efficiency retains some limitations.

With buildings responsible for 36% of EU greenhouse gas emissions and half the bloc’s energy demand, European cities will have to accelerate deployment of renewable energy and foster substantial investment in energy efficiency to become carbon neutral by 2050. A new report has found ‘solar skins’ are well positioned to help achieve that goal and multiply the contribution of rooftop solar.

According to an investigation conducted by public bodies, cross-mating of connectors was the main common denominator of the incidents studied.

Hanergy displayed the newest rendition of its 18.7% Thin Film Flat SOLARtile in Australia last week as it gears up for the U.S. and global product launch later in 2019.

Thin-film manufacturer says its skyscraper product, which can be retrofitted, will open up a new BIPV marketplace – but spokesman sidesteps question of whether Trump’s solar duties will apply in the US.
