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.
