Scientists fabricate all-organic solar cell with record 8.7% efficiency
A team of Japan-based scientists have set a new power conversion efficiency record for all-organic solar cells, more than doubling the previous record. They say the cell was developed with rganic electrodes with high conductivity that required no acid doping or high-temperature heating, which avoids damage to the plastic substrates.
Japan awards 1.4 GW of BESS in second long-term auction
Japan allocated 1.4 GW of battery energy storage (BESS) in the latest round of its Long-Term Decarbonization Auction (LTDA). The results showed BESS was the most oversubscribed technology, with only a fifth of the bid capacity awarded.
Saving money is the biggest driver of residential solar adoption
A recent study by Ohio State researchers finds that cost savings and other practical benefits are the key motivators for people to adopt rooftop or community solar.
Credence Solar unveils 600 W TOPCon PV panel
India’s Credence Solar has unveiled the Hyper Nova N TOPCon module series available in power outputs from 580 W to 600 W with front-side power conversion efficiency of 22.45% to 23.25%, respectively.
Oman seeks consultants for 500 MW solar project
The state-owned Nama Power and Water Procurement Company is looking for consultants to support the development of a 500 MW solar plant. Interested bidders can purchase tender documents until May 11, ahead of a deadline for applications on June 15.
European markets break records for solar production in April
AleaSoft Energy Forecasting’s latest analysis finds Germany, Portugal and Spain broke their records for solar production on a day in April last week, while Italy recorded its second highest daily figure ever. Meanwhile, weekly average electricity prices increased across most major European markets.
Artificial light tests for indoor PV
Researchers at the Universitat Politècnica de Catalunya in Spain evaluated 12 PV devices from 11 suppliers for indoor use, identifying several systems capable of powering remote sensor nodes with a 10 cm² surface area and advancing to testing under natural indoor light.
Cooling PV modules with porous silicon-carbide ceramic, PCM
Researchers in Iran developed a passive solar module cooling method using silicon carbide porous ceramic. When combined with phase change materials, the technique reportedly boosts panel performance by up to 7.4%.
PV module cleaning should be included in green building standards
Scientists in Sudan have called for the inclusion of PV module cleaning operations in green building standards to address a key maintenance gap in renewable energy systems. It would target improved system performance in environments where dust and soiling pose persistent challenges.
IPS unveils 8.1 MWh utility-scale BESS
IPS has developed an 8.1 MWh utility-scale battery energy storage system (BESS) housed in a 20-foot container with an integrated 4 MW inverter. The Bulgarian manufacturer says it aims to meet growing demand for efficient, large-scale energy storage solutions.
