There have been some commercially available cadmium telluride solar cells, from First Solar, that have gotten up to 20 percent.

现在还可以找到First Solar公司的碲化镉太阳能电池，能够将效能提高到20%。

“To absorb a useful amount of sunlight with silicon we would need to use around 200 micrometers of material. " Major said. " For absorbers such as cadmium telluride, we need to use only 1 percent of the same material.”

“要用硅吸收有用量的阳光， 我们需要使用大约 200 微米的材料。 ” 梅杰说。“对于像碲化镉这样的吸收体， 我们只需要使用相同材料的 1%。
