With solar grade polysilicon prices having plummeted in recent years, cutting down on consumption of the material has not been a priority. But strategies exist and significant savings can be made through deploying thinner wafers that use less silicon, insists a new paper published by MIT and NREL. And as manufacturers are increasingly hitting dead ends on other routes to cost reduction, this option could be back on the table for many.
UK researchers claim to have proved the viability wearable photovoltaic devices as an integral part of regular clothing. A solar-powered fabric textile was created by embedding micro crystalline silicon solar cells within the fibers of a textile through very thin copper wires. The scientists claim that the novel device can maintain its performance even after 15 domestic machine wash cycles, 25 hand wash cycles, and 6000 abrasion cycles.
Power generation statistics released by the National Energy Administration appear to confirm the nation added 12 GW of solar last month. China also deployed another 41 GW of polluting coal-fired power plants last year.
The Chinese manufacturer said the result was confirmed by Germany’s TÜV Rheinland. The achievement beats the company’s previous record of 21.65%, set last month.
The Chinese manufacturer has achieved conversion efficiencies of 21.82% and 22.49% for its p-type PERC and n-type HOT bifacial panels, respectively. The results were confirmed by Germany’s TÜV Rheinland.
Norwegian solar panel manufacturer REC Group has upped the ante with new warranty deals and reduced the annual power degradation of its products. In addition to a brand new, triple 25-year warranty exclusively offered by certified REC Solar Professional installers, it has extended coverage form 10 to 20 years for its TwinPeak and N-Peak products.
A team at the U.S. National Renewable Energy Laboratory has come up with a new process that would reduce the production cost of highly expensive – and highly efficient – gallium arsenide cells.
As the world strives to arrest the climate crisis and increases its investment in solar energy, the industry must address its own sustainability. A new report produced by Arup in Australia looks at how to apply principles of the circular economy to current and future PV waste management.
The PV manufacturer announced the development of the new solar panels, which feature new M12 series monocrystalline wafers, at a conference on Thursday in the Chinese city of Ningbo. The 50-cell modules are actually slightly bigger than 72-cell designs with 156.75 mm wafers, it said.
The Australian Renewable Energy Agency has announced $15 million in research funding to investigate the end-of-life issues for solar PV panels. Ultimately it is hoped the research increases solar PV efficiency and lowers the cost.
