Clime Capital invests $10 million in PV developer in Philippines
Singapore-based fund manager Clime Capital is investing up to $10 million in Upgrade Energy Philippines (UGEP). The money will go toward supporting commercial and industrial (C&I) and utility-scale solar deployment.
India proposes ALMM mandate for solar cells from April
India’s Ministry of New and Renewable Energy (MNRE) has started accepting feedback on draft guidelines for the Approved List of Models and Manufacturers (ALMM) for solar cells. The MNRE plans to implement the guidelines from April 2026.
Lightweight ventilated BIPV system for low-load rooftop applications
Scientists in China have designed a ventilated building-integrated photovoltaic system that relies on flexible solar modules with a weight of 6 kg/m2. The system also uses an airflow channel under the PV panels to reduce their operating temperature and increase their power yield.
Terpyridine-passivated perovskite solar cells achieve 25.24% efficiency
An international team of researchers demonstrated perovskite solar cells treated with a molecular passivator based on π-conjugated terpyridine Lewis-base molecules that achieved 25.24% power conversion efficiency, with 90% retained after 2,664 hours of light exposure. The treatment reportedly works at high concentrations without damaging the perovskite film or diminishing cell performance. A protocol was published to reproduce the results, opening the door to testing it on a range of perovskite absorbers.
