As attention on global warming grows and its impact becomes more apparent, renewable sources of energy are becoming more and more critical. 2025 was one of the warmest years to date, and it's only ...

One drawback of most solar cells made with efficiency-boosting perovskite is the presence of hazardous lead in the materials that turn sunlight into ...

A Hong Kong Polytechnic University team built a perovskite-organic tandem solar cell that holds 97% efficiency even when part of it is shaded. The design avoids reverse-bias stress, the damage ...

A new solar breakthrough may overcome a long-standing efficiency barrier. Researchers used a “spin-flip” metal complex to capture and multiply energy from sunlight through singlet fission. The result ...
