Solar panels can’t operate efficiently if they’re caked in dirt, but cleaning them regularly can be a time-consuming process. Engineers in Germany have now developed an ultra-thin coating that can ...

Researchers at the Massachusetts Institute of Technology recently developed a lightweight polymer coating for solar panels, designed to keep most gases from permeating the cells. A mere 60 nanometers ...

Researchers in India have demonstrated a wet chemical process to recover silicon with high purity from end-of-life solar panels, which they used to make functionalized silica nanoparticles. Tests of ...

Scientists in Egypt have created an anti-soiling coating for solar panels by mixing ethanol, deionized water, ammonium hydroxide and tetraethyl orthosilicate. They tested a coated panel outdoors for ...
