The other group, led by Dr. Xin Yu Chin at the Federal Institute of Technology in Lausanne, Switzerland, demonstrated an efficiency of 31.25 percent and said tandem cells had the “potential for both high efficiency and low manufacturing costs.”

Experts said that if the scaling-up of production of the tandem cells proceeds smoothly, they could be commercially available within five years, about the same time silicon-only cells reach their maximum efficiency.

听起来不错哦。

单个pn结有理论极限 不可能突破的

PV conversion efficiency is the percentage of incident solar energy that is converted to electricity. Though most commercial panels have efficiencies from 15% to 20%, researchers have developed PV cells with efficiencies approaching 50%.
