Photocurrent-determining processes in quasi-solid-state dye-sensitized solar cells using ionic gel electrolytes

Article Abstract:

The difference of (short-circuit current) J (sub SC) values between (dye-sensitized solar cell) DSCs using ionic and organic liquids was well interpreted by the limitation of transport of I (sub 3) (supper minus) and high concentration by the limitation of transport of I (sub 3) (supper minus) in viscous electrolytes. Slow diffusion of I (sub 3) (supper minus) caused the lack of the local concentration of I (sub 3) (supper minus) at the counter electrode, limiting the photocurrent in ILE.

Charge transport and back reaction in solid-state dye-sensitized solar cells: A study using intensity-modulated photovoltage and photocurrent spectroscopy

Article Abstract:

Solid-state dye-sensitized solar cells employing spiro-MeOTAD as a hole transport phase are studied by intensity modulated photocurrent spectroscopy (IMPS) and intensity modulated photovoltage spectroscopy (IMVS) over a wide range of illumination intensity. The IMPS and IMVS responses provide information about charge transport and electron-hole recombination, respectively.c

Dependence of the photocurrent conversion efficiency of dye-sensitized solar cells on the incident light intensity

Article Abstract:

The incident photon to current conversion efficacy of dye-sensitized solar cells is measured as a function of the incident photon current density. The strong dependence of the IPCE on the incident light intensity is of general importance for measurements of the IPCE of dye-sensitized solar cells and of nanocrystalline electrodes.
