Harvesting excess energy from above-bandgap photons could lead to solar cells which exceed conventionalefficiency limits.
捕获高于半导体带隙的光子的能量会导致太阳能电池的效率超过传统的效率极限。

Conventional solar-only devices with polymer absorbers have less than 10 percent efficiency.
而常规带有聚合物吸收器的单一太阳能设备的效率低于10%。

The nanostructure isn't immune to degrading, but this process is prolonged because its efficiency is 10 times greater than conventional batteries, Braun said.
