Effect Of Surface

The effect of surface modification to dye-adsorbed TiO2 electrodes in alkoxysilyl dye-sensitized solar cells on the photovoltaic performance was investigated with using alkylcarboxylic acids with different alkyl-chain lengths as surface modifiers. More effective suppression of a back-electron-transfer reaction was observed with the increment of the amount of the adsorbed modifier on the dye-adsorbed TiO2 electrode and with lengthening the alkyl chain of the alkylcarboxylic acid. The photovoltaic performance of the cells was confirmed to be improved by the surface modifications of the dye-adsorbed TiO2 electrodes using alkylcarboxylic acids, and the necessities of tuning the surface-modification degree and the selection of the alkyl-chain length with regarding the molecular size of the sensitizing dye were exhibited for the efficient improvement of the photovoltaic performance of the cell.

Sensitized Solar Cells

Chlorophyll a derivatives were integrated in “all solid-state” dye sensitized solar cells (DSSCs) with a mesoporous TiO2 electrode and 2′,2′,7,7′-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene as the hole-transport material. Despite modest power conversion efficiencies (PCEs) between 0.26% and 0.55% achieved for these chlorin dyes, a systematic investigation was carried out in order to elucidate their main limitations. To provide a comprehensive understanding of the parameters (structure, nature of the anchoring group, adsorption …) and their relationship with the PCEs, density functional theory (DFT) calculations, optical and photovoltaic studies and electron paramagnetic resonance analysis exploiting the 4-carboxy-TEMPO spin probe were combined. The recombination kinetics, the frontier molecular orbitals of these DSSCs and the adsorption efficiency onto the TiO2 surface were found to be the key parameters that govern their photovoltaic response.

The photovoltaic performance of quasi-solid-state DSSCs depends on the substituent and the substitution site of the imidazolium ring as well.
