UV-C light is now used in various places to kill Sars-Cov-2. Airplanes, NY subway and some grocery stores are using powerful UV-C light to disinfect.

However, no help from the sun.
While the sun does emit UV-C light, it does not reach Earth. Essentially the ozone layer blocks UV-C light from reaching our planet. We only experience UV-A and UV-B, which do not have the same disinfecting power as UV-C, especially when it comes to COVID-19.
And be careful at home
“Since UV-C has the potential to be dangerous due to eye damage, skin damage, or lung damage due to ozone that can be produced by UV devices, we urge people to be cautious in using UV devices,” says Hofmann.
He also adds, “Our message is that UV-C consumer products are new technologies and there are, at present, no recognized standards or certifications -- or even industry best practices for these devices. As such, it’s completely buyer beware”.
