DMEGC launches M10 rooftop solar modules with 410 W of output
China’s DMEGC has released new solar panels with power conversion efficiencies of up to 21.2% and temperature coefficients of -0.33% per degree Celsius. They can be used with maximum system voltages of 1,000 V or 1,500 V.
CEA-INES develops 18.95%-efficient flexible perovskite solar panels
French researchers have developed PV modules with an area of 11.6 square centimeters for indoor applications. They said the achieved efficiency level marks a world record for a flexible perovskite device larger than 10 square centimeters.
Spain hit by biggest solar radiation decline in 28 years in March
Spain recorded a 50% decrease in solar radiation due to bad weather in March – the biggest decline since the beginning of satellite records in 1994. By contrast, irradiation levels in Germany and the Balkans were 45% higher during the same period.
Photon-enhanched rechargeable batteries for solar storage
Japanese scientists have analyzed storage systems that combine PV and high-energy-density metal batteries. The rechargeable batteries have advantages such as low-charge voltage and high energy density, but stability and safety must be addressed before they reach commercial maturity.
Perovskite solar cells based on down-conversion materials
An international research group has assessed the potential of down-conversion materials to overcome the poor blue response of solar cells. They analyzed how such materials could be used to improve the performance of perovskite-based devices and found that certain advances might be achieved.
The Hydrogen Stream: Viritech, Pininfarina unveil world’s first ‘hydrogen hypercar’
Viritech and Pininfarina have announced plans to put a hydrogen-fueled car into limited production in 2023, while H2 Clipper said it aims to finish a prototype of its hydrogen-powered airship by 2025.
Novel floating PV system design from Norway
Norwegian scientists have tested a new floating PV system concept at a water reservoir in Sri Lanka. The system is made of composite beams to support the solar panels and high-density polyethylene (HDPE) pipes to provide buoyancy.
ISA opens global bids for solar cold storage in Africa
The International Solar Alliance (ISA) is overseeing bids from prospective contractors to supply, install and commission solar cold storage capacity in Senegal, Sudan, and Seychelles. Bidding is also open for two 2 MT systems in Djibouti.
Longi’s heterojunction solar cell hits 26.5%
Germany’s Institute for Solar Energy Research Hamelin has confirmed that Longi’s new n-type heterojunction solar cell has achieved a power conversion efficiency of 26.5%.
