A closer look at JA Solar’s new 785/810 W panel series
According to the product sheet, the new series has dimensions of 2,219×1,765x40mm and weighs 43.5kg. Efficiency reportedly ranges from 20.1-20.8% and the module features a 12-year product warranty and 25-year linear power output guarantee.
Testing CPM-based passive cooling for CPV systems
An international research team has tested change material heat sinks for heat management on a concentrator photovoltaic system. It found that increasing over height ratios lowers the formation of stratified liquid layers, which in turn reduces the potential hot spots in the upper part of the solar cell.
Talesun unveils 570-590 W solar module series
The new module series is available in five versions with power outputs claimed by Talesun of 570-590 W and reported efficiencies of 20.3-21.0%.
Solar modules with glass-enameled steel backs
U.S.-based Toledo Solar has secured a grant from the U.S. Department of Energy to conduct research on lighter, steel-backed solar modules.
Chinese PV Industry Brief: Higher cell prices and plans for 36 GW of new cell capacity
Chinese solar cell manufacturer Tongwei has raised its cell prices by 9% this week after having increased them by 10% three weeks earlier. Another cell manufacturer, Aiko Solar, has unveiled a plan to deploy 36 GW of new cell production capacity.
Jolywood announces bifacial panel with 615 W ouptut
Presented at the SNEC fair in China, the Niwa Super module series has a power output ranging from 570 W to 615 W and a reported efficiency of 22.1%.
Photo-electrochemical cells vs. PV electrolysis
Dutch researchers have analyzed the two most promising solar-assisted technologies to produce green hydrogen, based on the levelized cost of hydrogen. They found that PV-powered hydrogen production offers the lowest costs, at $6.22/kg, with a solar-to-hydrogen efficiency ratio of 10.9%.
Designer molecules enable ‘two for one’ efficiency boost
Scientists in the U.S. have come a step closer to taking advantage of singlet fission – a phenomenon seen in certain solar cell materials that promises to greatly increase energy yield. By designing and testing various molecules, the group was able to better understand the fundamental processes behind the mechanism and optimize materials to better take advantage of it.
Fraunhofer ISE claims 25.9% efficiency for III-V tandem solar cell
The new results mark an improvement on the institute’s previous 24.3% efficiency record. The III-V tandem solar cell is directly grown on silicon.
Power-to-gas facility in Canada could pay back in just under three years
The facility’s size and operational pattern could be optimized using a mixed-integer linear programming-based model. By selling hydrogen, supplying grid ancillary services and selling by-product oxygen, power-to-gas economics could be dramatically improved.
