摘要: Dye-sensitized solar cells (DSCs) have gained widespread interest because of their potential for low-cost energy conversion. Currently, the certified record efficiency these is 11.1%, and measurements durability stability suggest lifetimes exceeding 10 years under operational conditions. The DSC a photoelectrochemical system: monolayer sensitizing dye adsorbed onto mesoporous TiO2 electrode, electrode sandwiched together with counter electrode. An electrolyte containing redox couple fills gap between electrodes. key component DSC. reduced part regenerates photo-oxidized dye. formed oxidized species diffuses to where it reduced. photovoltage device depends on sets electrochemical at also affects through recombin...
