How to Make a Solar Cell From Gallium Arsenide
Aims to reduce the rate of radiative recombination by making a perfect crystal for two things. Howd so how do you slow down the non-radiation loss ros? You you reduce the avoidable losses by having really good quality material. And that's what they didit's a really col idea, and they made it. The idea was known, but they made it work by a techniqal epitacil lift off andand, you know. It only makes sense to invest effort in doing that when you've already dealt with non radiative recombining.
