University of Manchester signs PPA for new 71 MW UK solar project
The corporate power purchase agreement is billed as the largest signed by a UK educational institution. Agreement provides fixed-rate revenue for developer Enviromena. EDF is the utility responsible for balancing and shaping generation.
Reducing PV module temperature with ultra-cooling patch
Scientists in Hong Kong have developed a patch that effectively cools down PV panels and utilizes waste heat for freshwater production. It has three layers: an atmospheric water harvester, a thermal regulation layer, and an adhesive layer. Maximum power density reportedly increased by over 28% in a folded version of the ultra-cooling patch.
Ireland curtails almost 89 GWh of solar in H1
Commenting on its report on Ireland and Great British renewable energy curtailment, Montel Energy’s Fintan Devenney described Great Britain’s solar curtailment as “negligible” during the first six months of 2025. Solar curtailment in Ireland has increased sevenfold since 2022, the report found.
The Hydrogen Stream: Oman launches green hydrogen auction
Oman has opened its third green hydrogen auction, with state-backed Hydrom offering new investment opportunities for qualified developers in the country’s expanding hydrogen sector.
Activ8 Energies acquires Low Carbon Energy to expand UK solar portfolio
Activ8 Energies, 50% owned by SSE Airtricity, has acquired all shares of UK-based Low Carbon Energy (LCE) to strengthen its commercial and industrial (C&I) solar portfolio in the United Kingdom.
US scientists claim 15-fold performance increase for solar thermoelectric generator
A research team have fabricated a solar thermoelectric generator (STEG) that is reportedly 15 times more efficient than current state-of-the-art devices by concentrating on the managing the hot and the cold sides of the device rather than its semiconductor materials.
Improving roll-to-roll slot-die coating via machine learning
University of Sheffield researchers developed a machine learning framework to improve coating properties in a roll-to-roll slot die coating process. The work is seen as an initial step toward broader use of machine learning and related technologies to assist with optimization.
Indoor perovskite solar cell built with triple passivation strategy achieves 37.6% efficiency
An international research team has constructed an indoor perovksite PV device by using a triple passivation treatment to reduce crystal defects in the perovskite film. The cell achieved remarkable efficiency and was also able to retain 92% of its initial performance after 3,200 h.
