The race to build the world’s most efficient solar cell is no longer a theoretical contest inside physics labs, it is a high‑stakes engineering sprint that will shape how quickly the global energy ...

Imagine two homes on the same street, with the same-sized roofs, both fitted with solar panels. Yet one home consistently generates more electricity than the other. The difference comes down to solar ...

Researchers in the U.S. have developed a set of guidelines and protocols to assess the performance of three-terminal (3-T) and four-terminal (4-T) tandem solar cells, including those with subcells ...

Defect-filled lead-halide perovskites rival silicon solar cells because domain walls inside the material separate and guide charges. Researchers visualized these charge-transport networks using a ...

Earlier in 2025, Chinese solar manufacturer Longi announced it had built the world's most efficient solar cell. The hybrid interdigitated back-contact (HIBC) cell achieved 27.81% efficiency, which was ...

Monocrystalline, polycrystalline or thin-film? Here’s how the main types of solar panel compare on efficiency, lifespan, and the roof space you’ll need.

A research team in Italy has tested the performance of semitransparent wide-bandgap perovskite solar cells in underwater (UW) environments and has found that, at a 0.5–1 cm depth, the devices achieve ...

Given the enormous long-term savings and environmental benefits, there's never been a bad time to install solar panels, but 2025 is shaping up to be an especially favorable year to take the plunge.

Researchers at The Hong Kong University of Science and Technology (HKUST) have developed a multi-source co-evaporation recipe ...

A team from the University of Stuttgart, together with international researchers, has succeeded in enhancing both the efficiency and environmental resilience of perovskite solar cells. This is another ...

The research team developed the perovskite solar cell with a spin-coated bilayer tin oxide electron transport layer that boosts charge extraction, achieving a 4.52% efficiency and improved stability.

Terrestrial-based data centers are power-constrained, land-intensive, and consume significant volumes of water for cooling. Space-based data centers are freed from these environmentally intensive and ...
