Questions for “Flexible devices may help clothes solar power your screens”

Bent by tweezers, a flexible solar concentrator emits red light when blue light is beamed onto it. The sun emits such wavelengths of light. If used to coat fabrics, such concentrators could harvest sunlight to power someone’s phone or other electronics.
