Accelerated ageing tests on large numbers of nanocrystalline dye-sensitised solar cells (nc-DSC) show that, to first order, separation between the effects of the stresses of visible light soaking, UV illumination and thermal treatment on long-term st

The incident photon to current conversion efficiency (IPCE) of dye-sensitized solar cells is measured as a function of the incident photon current density. A characteristic dependence of the IPCE on the incident light intensity with a maximum value f

Measurements of the electroluminescence of dye-sensitized solar cells are presented for the first time. Forward biasing of a dye-sensitized solar cell leads to electron injection into the dye which is adsorbed on a nanocrystalline TiO2 film. Applicat

Electron accumulation in illuminated dye-sensitized nanocrystalline TiO2 photovoltaic cells has been detected by measuring the photoinduced change in transmission at 940 nm. The sensitivity of the transmission measurement was enhanced by using intens

Oxygen- and water-related surface defects on porous TiO 2 (anatase) can be well controlled by the oxygen and water partial pressures and therefore such defects are of technological relevance for dye sensitized TiO 2 solar cells. We investigated the a
