Kyrgyzstan, Hungary sign $300 million solar development deal

Kyrgyzstan’s National Investment Agency and Hungary’s Electron Holding have agreed to develop up to 300 MW of solar capacity in Kyrgyzstan with planned investments of $300 million.

PV topics dominated the International Solar Energy Society’s Solar World Congress 2025 in Brazil

In its latest monthly column for pv magazine, the International Solar Energy Society (ISES) promotes the biennial Solar World Congress (SWC), which took place in Fortaleza-Brazil in November 2025, a few days before the COP30. The SWC scientific program has traditionally been dominated by presentations on solar radiation and solar thermal applications, but this year, photovoltaics was the focus of most of the presentations. This reflects the massive adoption of PV all over the globe, which, at the current pace, will dominate the electricity mix by the end of the decade.

Perovskite solar cell based on Mxene achieves record-breaking efficiency of 25.75%

A research team in Spain has built what it claims to be the world’s most efficient perovskite solar cell using MXenes or any other type of 2D-materials. The device relies on a Mxene interlayer that suppresses non-radiative recombination and improved charge extraction at the interface between the perovskite absorber and the electron transport layer.

Indian utility seeks land for new grid-connected solar project

NLC India Ltd. says it has issued a tender for contractors to secure and develop 1,850 acres across multiple states for a solar power project connected to India’s inter-state transmission system (ISTS) on behalf of NLC India Renewables Ltd (NIRL).
