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.

AbstractA four phase model air/glass/indium doped tin oxide/TiO2 has been studied by modifying Rouard’s model to calculate the final transmittance from TiO2 layer to be used as photoanode in dye-sensitized solar cells. An optical simulation for the reflectance and transmittance has been executed for the constructed nanocrystalline TiO2 films. To validate the theoretical results TiO2 film has been deposited onto indium doped tin oxide (ITO) layer by sol-gel dip coating technique. It has been found that the incident light suffers losses by 5-15% on passage through TiO2 coated ITO layer. Experimentally it has been observed on the basis of efficiency value that meso-nano combination is the best candidate to be used as photoanode in a dye-sensitize solar cell.

Porous aluminium doped TiO2 was prepared through a sol–gel process in the presence of a template. The doping enlarges the band-gap of the anatase TiO2, which modifies the TiO2 electrical properties. The porous Al/TiO2 films were assembled into dye-sensitized solar cells. A 45 mV enhancement of open-circuit photovoltage and 11% increase of fill factor at 2 wt-% doping concentration, and 8.6% improvement of the overall efficiency at 0.5 wt-% doping concentration were achieved relative to that of a cell containing non-doped TiO2 under the same conditions. This advance is attributed to the increase in conductivity with the Al-doping of the TiO2 electrode.
