太阳光转化效率的计算? Photovoltaic efficiency? Solar fuels, 'efficiency can be defined in many ways One must be cautious when interpreting the literature, as some definitions of efficiency( % ) do not reflect how efficiently a device would produce fuels from sunlight in commercial applications Two general types of efficiency definitions The one true indicator of device performance: Solar-to-fuel efficiency (STF),e.g. solar-to-hydrogen(STH Diagnostic efficiencies Provides information to the researcher one the fundamental physical and chemical workings of the device. a high efficiency for these measurements does not necessarily translate to high STF/STH efficiency Applied bias photon-to-current efficiency (aBpe) External quantum efficiency (EQe)= incident photon-to-current efficiency(IPCe) Internal quantum efficiency (IQE)=absorbed photon-to-current efficiency(APCE 88 太阳光转化效率的计算？
