U.S. scientists build antimony sulfide solar cell with 7.69% efficiency
Researchers at University of Toledo produced antimony sulfide (Sb2S3) thin film solar cells with 7.69% power conversion efficiency after determining optimal hydrothermal deposition, post annealing, and light soaking conditions. Stability tests showed more than 95% of initial efficiency after ten months.
Solavita launches 30-50 kW hybrid inverter series
Chinese inverter maker Solavita says its new hybrid inverter series offers high PV oversizing, multi-port battery integration, and grid-smart controls to meet growing demand for scalable solar-plus-storage in commercial and industrial (C&I), and large residential markets.
US clean energy sector takes $14 billion hit as tax credits face repeal

TotalEnergies, RGE to develop solar-plus-storage in Indonesia
TotalEnergies and RGE have signed a co-investment agreement to develop and operate a solar-plus-storage project in Indonesia. The utility-scale plant will be built and managed by Singa Renewables, their equally owned joint venture.
East coast irradiance dips as storm systems dominate May
In a new weekly update for pv magazine, Solcast, a DNV company, reports that a low-pressure system over central North America in May suppressed solar irradiance on the East Coast while supporting moderate gains in the West and Midwest.
Edinburgh Instruments unveils spectrofluorometer for perovskite, organic solar cells
The new FS5 v2 Spectrofluorometer is available as a benchtop system for fluorescence spectroscopy.
‘Emotions are not a liability’
This week Women in Solar+ Europe gives voice to Patricia Dárez, managing director at Spain’s 350Renewables. She explains that one of the most persistent stereotypes about women in leadership is that emotion has no place in professional settings. “Emotions are what make us care about the work we do, the people we do it with, and the future we’re shaping,” she states.
Unpacking the rationale behind low bids in the EU green hydrogen tender
BloombergNEF and Wood Mackenzie analysts spoke with pv magazine about the EU’s €992 million ($1.04 billion) hydrogen tender that drew record-low bids thanks to strong design incentives. They outlined the factors behind the tender’s competitiveness but cautioned that not all awarded projects may move forward.
PV-powered fine sand solar geyser for domestic hot water
The system is described by its creators as a cost-effective solution for water heating by storing thermal energy in fine sand. Techno-economic analysis indicated the system is economically viable for domestic water heating applications, with an initial capital cost of $278 and an expected lifespan of 25 years.
