Italian startup develops thermo-mechanical PV panel recycling process
Venice-based 9-tech has developed a thermomechanical process to recycle end-of-life PV panels, with early results showing an 87% recovery yield of materials such as silicon, copper, and silver.
Chinese solar module prices fall despite price hikes in upstream segment
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
POLO back junction solar cell built with PECVD achieves 24.2% efficiency
A group including scientists from Insititute for Solar Energy Research Hamelin (ISFH) and German PV equipment manufacturer Centrotherm has developed a POLO back junction solar cell by using an industrial plasma enhanced chemical vapor deposition (PECVD) system with a low-frequency plasma source. The device achieved a slightly higher efficiency than a reference device fabricated via more expensive atomic layer deposition (ALD).
Freeware tool predicts light transmission, power generation of PV materials used in agrivoltaics
A research paper from scientists at Swansea University describes their tool for analyzing thermodynamic limits of organic semiconductor-based photovoltaics (OPVs). One of the findings was that semi-transparent solar PV deployed in greenhouses may deliver comparable performance to conventional crystalline silicon PV.
Italy’s first agrivoltaic tenders draws bids for 1.7 GW
Italy’s Ministry of the Environment and Energy Security (MASE) says it has received 643 bids totaling 1.7 GW in its first agrivoltaic tender. About 56% of the proposals have come from the country’s sunny southern regions.
Belgium to allow plug-in solar panels, batteries
Belgium’s transmission and distribution system operator says it plans to allow household solar panels and batteries with a plug and socket to connect to the grid from May 2025.
New solar carport opens at 4,300 meters on Mount Everest
Chinese module maker Aiko Solar says it has built a 150 kW off-grid solar carport at an altitude of 4,300 meters on Mount Everest, featuring 645 W bifacial dual-glass modules and 200 kWh of battery storage.
Longi achieves 34.6% efficiency for two-terminal tandem perovskite solar cell prototype
In a paper published in nature, the Chinese module maker explained that the 33.9%-efficient tandem device it unveiled in December 2023 is based on a bilayer intertwined passivation strategy that combines efficient electron extraction with further suppression of nonradiative recombination. It also revealed that its two-terminal tandem prototype devices achieved an efficiency of 34.6%.
Optimizing bifacial solar panels for floating PV applications in tropical freshwater
New research from India shows how bifacial solar modules should be deployed to achieve strong performance in floating PV projects planned on tropical freshwater. Their experimental setup demonstrated that higher efficiency gains are achievable by gauging panel height, water depth, and tilt angle.
Australian commercial indoor perovskite solar cells coming soon
Halocell Energy, an Australian perovskite solar cell developer, is close to bringing its first indoor solar product to market.
