Solar panels can help cut your energy bills – here’s how they generate power, what happens to the electricity you don’t use, ...

A solar cooler uses energy from the sun to run a cooling system—just like how a fridge or air conditioner works, but without using regular electricity. These technologies are like the solar panels ...

Forbes contributors publish independent expert analyses and insights. Dianne Plummer is an Energy Consultant and Certified Energy Manager. In 2024, rooftop solar was the fastest-growing source of ...

A flexible perovskite-silicon tandem solar cell has reached a certified 29.88% power conversion efficiency, placing it among the highest recorded results for this class of device and bringing the ...

Researchers have developed a perovskite-organic tandem solar cell that achieves 26.4 percent efficiency. Unlike rigid silicon modules, the lightweight design can generate power on curved or flexible ...

In a study published in Nature, researchers at Linköping University have developed a method to recycle all parts of a solar cell repeatedly without environmentally hazardous solvents. The recycled ...

Ubiquitous Energy and Michigan State University researchers have created a fully transparent solar concentrator, which could turn any window or sheet of glass (like your smartphone's screen) into a ...

Rethinking solar panel geometry beyond the traditional rectangle can unlock significant energy potential by optimizing coverage on complex, irregular rooflines.

While they may appear to be insignificant, raindrops’ impact on surfaces can create measurable electrical signals when specific conditions exist. Scientists from Spain have now demonstrated that the ...

The transparent four-terminal perovskite solar cell employs an ion-modulated spiro-MeOTAD hole transport layer, which passivates interfacial defects, enhances carrier dynamics, and allows for a ...
