Organic semiconductor colloids: From the knowledge acquired in photovoltaics to the generation of solar hydrogen fuel

The recent interest in the application of organic semiconductor colloids to photocatalytic hydrogen evolution has sparked need for an assessment current state this research field. Here, we showcase how lessons learned from photovoltaics (OPV) can be applied new applications generation solar fuels, such as evolution. Photovoltaics generated nanoparticles (NPs) started with a power conversion efficiency at less than 0.01% 2003, since then technology witnessed steady climb 7.5% reported 2018. A large fraction improvement attributed morphology colloids, improvements which now transferred benefit field We begin introduction conjugated materials, move thorough description NP dispersion processes, comprising miniemulsion and nanoprecipitation methods, before moving summary different morphologies encountered NPs, their impact on OPV performance parameter is crucial importance generation. Indeed, conveniently provide nanoengineering toolkit upon customize increase activity enhance rates (HER).
