Discover how to build a simple solar cell at home using everyday materials! This step-by-step tutorial demonstrates how to repurpose an aluminum can, a CD, copper wire, toothpaste, lemon juice, and a ...

A novel thin-film technology enables solar panels to generate electricity from both sunlight and raindrops.

Learn how to build a simple solar cell at home using copper tape, plastic cups, and water. This step-by-step science experiment demonstrates how to harness solar energy to generate electricity.

Perovskite solar cells shouldn’t work as well as they do—but they do. Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric ...

A salt called guanidinium thiocyanate can improve the efficiency and stability of perovskite solar cells, a new class of semiconductor that could make solar power cheaper and more powerful, according ...

A study carried out at the Federal University of ABC (UFABC), in the state of São Paulo, Brazil, presents a new way to mitigate the rapid degradation of perovskite solar cells. The problem, which ...

Perovskite solar cells are one of the hottest topics in photovoltaics, because they are substantially more energy-efficient to produce than conventional silicon solar cells. Laboratory devices now ...

A KAIST research team has solved the "solar cell dilemma," in which increasing efficiency shortens lifespan, while extending lifespan lowers efficiency. The team developed a technology to precisely ...

Researchers in Sweden developed a bifacial chalcoprite solar cell using a titanium-doped indium oxide (ITiO) back contact, achieving 68% bifaciality. The device is able to maintain strong front-side ...
