Chinese PV Industry Brief: Shandong province wants to deploy another 35 GW of PV over the next five years
In addition, JA Solar was able to ship 10 GW of modules in the first six months of the year and raise RMB5 billion for new production capacity.
Coupling PV-powered electrochemical water splitting with battery storage
A German research team has developed a photovoltaic-electrochemical device for alkaline water electrolysis that can be linked to battery storage. The proposed system configuration can not only smoothen out the PV power fluctuations and facilitate power coupling, but also improve solar to hydrogen efficiency.
Bullish clean energy stocks helped maintain healthy investment levels
The latest renewables investment report produced by analyst BloombergNEF has noted backing for solar projects continued to rise in the first half as wind power investment fell back.
Mini perovskite solar module with 19.2% efficiency via new additive
The efficiency of the module was certified by the U.S.’ National Renewable Energy Laboratory. It was built with perovskite solar cells with a stabilized efficiency of 23.6%, an open-circuit voltage of 1.17 V, a short-circuit current density of 24.1 mA per cm−2, and a fill factor of 0.842.
Green roof improves solar panel efficiency by 3.6% on average
The comparison of two solar cladded roofs in Sydney, Australia, one bare beneath its panels and the other adorned with native grasses and plants, has found the panels on the green roof were, on average, 3.63% more efficient, producing an average daily output 13% greater than the conventional roof. The improvements are believed to stem from the lower temperatures on the green roof, thanks to its plants – which also provided a plethora of additional benefits.
Chinese PV Industry Brief: Longi raises PV wafer prices, new entrant switches on 15 GW of wafer capacity
GokinSolar has commissioned the first 15 GW unit of its 50 GW PV wafer manufacturing facility in Zhuhai City, Guangdong Province and Golden Solar New Energy Technology last week announced commercial production plans for the flexible, lightweight, cast-mono, heterojuntion (HJT) solar modules. Meanwhile, Longi has raised the prices of its wafers.
The best PV tech for Internet-of-Things devices
U.S. scientists have evaluated three different PV technologies – GaInP, GaAs, and silicon – for powering wireless temperature sensors. They found that the silicon solar module offers the lowest performance and also suggested its use may be applied to low-demand devices.
Trina Solar improves efficiency of 210 mm PERC solar cell by 0.5%
The cell has achieved a power conversion efficiency of 23.5%. The result was confirmed by China’s National Center of Supervision and Inspection on Solar Photovoltaic Product Quality (CPVT).
Ultra-lightweight CIGS solar module for high altitude airship applications
The 25 W solar panel has been designed to operate at air mass zero (AM0), which is the standard spectrum outside the Earth’s atmosphere. According to the PV manufacturer, the module has a weight of just 82 grams, while a small 300 W array comprised of these panels would weigh in at around 1 kg.
US customs enforcement is jeopardizing 2.1 GW of solar projects
Solar product detentions at U.S. ports of entry all stem from a June 24 “Withhold Release Order” issued by Customs and Border Protection.
