寄生吸収具体怎么用大白话解释呢？

兰兰爱学习

读文献总会出现寄生吸収这个词 比如太阳能电池要减少光的寄生吸収  我知道寄生吸収不好 但是具体怎么形象通俗易懂的去解释这个寄生吸収呢？

Parasitic absorption refers to an optical absorption process which does not generate an electron/hole pair; it competes with band-to-band absorption to decrease the photocurrent. A simple model for light trapping that includes PA is described for interpretation of experimental data.

以上内容引用自附件中的文献。大概意思就是说有机层吸收了光子但并没有形成激子。
