Hot-carriers in organic photovoltaics

چکیده

Abstract Photogenerated charge carriers in organic photovoltaics (OPVs) suffer relaxation and recombination losses. However, extracting these at higher energy (‘Hot-carriers’) has been found to be effective overcome such loss pathways improve efficiency of OPVs. Excess long delocalization length promotes hot-carrier escape from Coulombic attraction dissociation into free charges. Here, I have reviewed the ways generate hot-carriers their extraction backbones. In-depth understanding energetics dynamics will help designing photovoltaics.

Organic photovoltaics

In the last ten years, the highest efficiency obtained from organic photovoltaics (OPVs), such as bulk heterojunction polymer:fullerene solar cells, has risen from 2.5 to 11 %. This rapid progress suggests that the commercialization of OPVs should be realized soon if we can solve some technical issues. The advances in the development of OPVs can be attributed to four fronts: (i) a better unders...

Norris Optical Materials Engineering Laboratory, ETH Zürich We will discuss two recently observed phenomena with implications for photovoltaic devices. First, it is well known that conventional silicon solar cells lose a significant fraction of their absorbed energy when electrons that are excited high into the conduction band cool to th...
