An international research group has reconstructed the trajectory of p-type wafers in the heterojunction solar cell segment and has identified the lack of knowledge about boron-oxygen related light-induced degradation (BO-LID) as the main cause for the limited adoption of these wafers and the success of their n-type counterparts. According to the scientists, however, there is still big room for improvement for p-type technologies in heterojunction cells.
New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.
The novel technique consists of attaching cotton wicks immersed in the water (CWIWs) to the backside photovoltaic module. The water is supplied to cotton wicks from top to bottom by gravity which the scientists said helps the effective absorption of cotton and reduces water consumption.
A new report from the Taiwanese market research company shows growth in the production of modules over 600 W and increased format size. Cells and wafers are getting larger as well.
The results of the study by Wells Fargo Foundation and NREL initiative showed that PV-coated windows can appreciably lower the solar heat gain coefficient.
US startup New Use Energy Solutions has launched a new line of portable PV systems built with a module technology relying on Merlin Solar’s panels. The modules are assembled in the system via a custom vinyl tarp.
German company Flaxres has developed an industrial process to recycle PV modules, and has begun operating a pilot facility at its new site where 10 tons of solar modules can be recycled daily. Flaxres plans to make equipment based on this facility available to international customers.
Researchers in the United Arab Emirates have compared the performance of compressed air storage and lead-acid batteries in terms of energy stored per cubic meter, costs, and payback period. They found the former has a considerably lower Capex and a payback time of only two years.
Recycling solar panels keeps them out of landfills, but also provides much-needed raw materials with Rystad Energy projecting a value approaching $80 billion by 2050.
