Hans J.Queisser的detailed balance limit for solar cell efficiency的文章中,其中说到“we just considered "one sun", that is we neglected ways of concentration of the impinging sunlight. if one uses a lens, then one reduces the entropy,and that immediately means an increase of the conversion efficiency”
也就是说利用了透镜后,系统的熵减小了,这是可以理解的,但从这出发直接得出电池效率必然增加的结论是我一直没想明白的,不知科学网中能不能找到答案。
