Sun-Smart Innovations: Anti-UV Gear and Solar Power on the Go

The video discusses the dangers of sunburn and introduces anti-UV beach accessories like T-shirts and parasols that offer superior protection. It also explores a solar-powered backpack that charges devices using ambient light, inspired by photosynthesis. The video highlights the potential of dye-sensitized solar cells for generating electricity, even in low light, and their future applications in buildings.

Describe the innovative technology behind the flexible solar panel used in the backpack.

What is the principle behind the solar cells developed by Professor Michael Gretzel?

How do the new solar cells compare to traditional photovoltaic cells in terms of efficiency?
