Can a new technique for capturing 'hot' electrons make solar cells more efficient?

"physical mechanism responsible not only for the charge transport across a silicon surface but also for the final manipulation step, where a molecule excited by an electron is ejected from the silicon surface, but crucially only after the hot electron has already lost its excess thermal energy. For the first time, we've linked the energy dependence of this manipulation step to the underlying surface electronic band structure... creating defects alter energy landscape, or regulating the material temperature"
