An international research team has improved the performance of perovskite indoor photovoltaics by tuning the absorber bandgap to better match the emission spectrum of indoor LED lighting. The approach enables improved spectral alignment under low-light conditions, with devices demonstrating efficiencies of up to 37.44% alongside long-term stability exceeding 2,000 hours.

Bhutan has kicked off a tender to develop 12.1 MW of rooftop solar across 73 public healthcare facilities in the country. The initial deadline to submit expressions of interest is May 29.

UK-based consultancy Ricardo, part of the WSP Group, reports that EU-27 day-ahead power markets saw 1,223 negative-price hours in Q1 2026, more than double Q1 2025, driven mainly by Spain, Portugal, and Greece, while Nordic markets fell back to zero after prior spikes. Germany’s April 2026 data shows negative prices aligning with large renewable forecast errors and likely curtailment during oversupply periods.

Perigus Energy has named Meta, Amazon, Johnson & Johnson, Flogas, and SWW Wunsiedel as corporate power offtakers, confirming that 204.85 MW – just more than 35% of its 578 MW operational portfolio – is contracted through corporate power purchase agreements (PPAs).

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.

At the Solarpower Summit in Brussels, two Ukrainian representatives highlighted the role photovoltaics and battery storage can play in the country, as well as the lessons the European Union can draw from Ukraine’s experience of living through war. Particular emphasis was placed on systems installed at hospitals and schools.

A remote Western Australia First Nations community with its sights set on reducing diesel dependence and energy insecurity has had a solar and 3.25 MW battery energy storage project approved for development.

The $200 million investment will bring the company’s total domestic production capacity to 6 GW by late 2026.

A China-based research team conducted a systematic review and meta-analysis of 147 studies on how solar PV systems alter land surface processes, covering 609 installations worldwide and 11 key climate variables. The results show mixed but mostly significant environmental effects, including reduced wind speed, albedo, and land surface or soil temperatures, alongside increased soil moisture, while air temperature changes remained largely non-significant.

The German manufacturer launched two mounting systems for utility-scale solar projects and small- and medium-scale installations, respectively. Both are designed to streamline installation with simplified components and modular layouts.
