"Engineers from the University of California at Los Angeles created a material from nanopolymers that can bend toward the light source like plants," according to the materials of https://hightech.fm/. Such a polymer can increase the efficiency of devices that convert light energy for 4 times.
After analyzing the previous development of flexible materials that bent towards light when the molecules change its orientation and were highly dependent on temperature and light intensity, the researchers created polymers that were deformed not in parts, but in whole. The photosensitive polymers developed by them were compressed and asymmetrically deformed bending towards the light source under the influence of light and an increase in temperature.
Researchers believe that new polymers can be used in solar panels and will provide four times greater ability to convert light energy into thermal energy than static photoconverters.
