#CGTN纪录片#【#人类碳足迹#：可再生能源的优势与困境】中国在光伏发电领域取得举世瞩目的进展，但光伏板的能量转化效率依然是需要攻破的难题，因此我们要在遥远的沙漠铺设大量的光伏板。那么，如何让光伏离我们更近一些?@杨钊YangZhaoTIO #太阳能电池板# #太阳能# #双碳# #碳中和# As the world embraces solar power, relatively low energy conversion efficiency of solar panels is still a problem to be overcome. So we have to built super large solar farms in remote areas, where only a few people live there. How can we bring renewable energy closer to us?
