Large improvement of photon capture for a dye-sensitized solar cell integrated with a fluorescent layer

An integrated design of dye-sensitized solar cell with fluorescent layer is realized. A fluorescent layer is deposited on a fluorine-doped tin oxide (FTO) glass with a blank right above a N719 dye-sensitized TiO2 coating which is printed on the central area of the conductive face of the FTO glass. Current density–voltage characteristic measurement indicates that our integrated system largely enhances photon harvesting by 44% compared with a cell without a fluorescent layer, which is attributed to the improvement of photon harvesting from the spectrum range and the space area.
