JinkoSolar claims 33.84% efficiency for perovskite-silicon tandem solar cell
The result was confirmed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences (CAS).
New research sheds light on impact of sodium-induced degradation in heterojunction solar cells
University of New South Wales researchers investigated the impact of sodium-induced degradation in heterojunction solar cells under accelerated damp-heat testing. They considered three different types of sodium salts and identified the degradation mechanisms attributed to each contaminant.
Prospects for reusing silicon from end-of-life solar modules in new ingot production
Scientists in the Netherlands proposed a new testing scheme for recycling silicon from end-of-life photovoltaic panels. Their methodology helped create different wafer categories for recycling silicon for new ingot production but also showed that most of recycled silicon in the near future will come from p-type products, which will harldy be reutilized in a market now dominated by n-type modules.
Bifacial perovskite solar can achieve bifaciality of 90% when tilted at 20 degrees
IIT Bombay researchers have shown that bifacial perovskite solar cells can achieve a 2% higher power conversion efficiency with a tilt angle of 20 degrees. They also developed a bifacial perovskite solar cell for applications in both tandem or single-junction PV devices.
Nexwafe claims 24.4% efficiency for heterojunction solar cell built with its ultrathin wafers
The German wafer manufacturer said the efficiency was achieved with an unspecified M6 HJT commercial production line, without specifying if the result was certified by an independent third party.
Combining floating PV with compressed air energy storage
Researchers from Egypt and the UK developed a new floating PV system concept that utilizes compressed air for energy storage. The system has a roundtrip efficiency of 34.1% and an exergy efficiency of 41%.
Hungary deploys 1.3 GW of solar in January-October period
Hungary installed 1.3 GW of solar between January and October, bringing its cumulative PV capacity to 7.3 GW by the end of October, according to new government data.
Japan aims to deploy 20 GW of perovskite solar by 2040
The Japanese government says it expects perovskite solar modules to be produced in large quantities at JPY 20 ($0.13)/W by 2025, JPY 14/W by 2030, and JPY 10/W by 2040.
LCOE not correct optimization parameter of solar PV plants, say researchers
New research from Italy shows the importance of considering power plant dispatchability in PV project planning. The scientists claim assessing a project’s levelized cost of energy could be misleading, especially with variable and sometimes negative electricity prices.
Japan’s 22nd solar auction concludes with lowest bid of $0.049/kWh
Japan has allocated 56.4 MW of PV capacity in its latest procurement exercise. The lowest bid came in at JPY 7.5 ($0.049)/kWh, while the average final price was JPY 8.17/kWh.
