A flexible perovskite-silicon tandem solar cell has reached a certified 29.88% power conversion efficiency, placing it among ...

Tiny crystal “seeds” could solve a hidden flaw in perovskite solar cells—unlocking high efficiency at larger scales.

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) in China have ...

Solar power is getting cheaper and more powerful, but researchers are still working to make the next generation of solar panels reliable enough for large-scale use. A new study reports a promising ...

Many new energy technologies look impressive in the laboratory but never become real products. Solar cells are a clear example. Scientists can achieve record performance under controlled conditions, ...

Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related ...

According to Qcells, notice letters recipients are infringing on its laser-enhanced contact optimisation (LECO) technology. Image: QCells. Korean-owned solar manufacturer Hanwha Qcells has issued ...

Metal-halide perovskite solar cells are attractive for next-generation photovoltaics due to their low fabrication cost and rapidly rising efficiencies. However, exposure to light and oxygen generates ...

Inverted perovskite solar cells offer strong potential for scalable, low-cost solar power, but a hidden interface inside the device has limited their performance and durability. Researchers have now ...

If you rewind the clock fifteen or twenty years, residential solar energy was a tough sell. The systems were incredibly expensive, wildly inefficient, and—let’s be brutally honest—they were usually an ...
