“…They can also offer adequate transparency contrary to metals. Flexible dye solar cells are therefore commonly based either solely [1][2] or partly on polymer substrates [3][4][5]. Several low temperature methods have been presented to prepare both the photoactive and the catalyst layers.…”

Atomic layer deposited TiO 2 recombination blocking layers were prepared on ITO-PET photoelectrode substrates for dye solar cells and examined using several electrochemical methods. The blocking layers increased the open circuit voltage at low light intensities. At high light intensities decrease of the fill factor due to additional resistance of current transport through the layer was more significant than the positive effect by the reduced recombination. The decrease in the fill factor was reduced by thermal treatment that made the blocking layer more conductive due to a structural change from an amorphous to a crystalline form. Therefore, thinner blocking layers of this type are required for plastic cells prepared at low temperature than for conventional glass dye solar cells made with temperature processing.

“…StS has been used both as counter electrode (CE) [4][5][6][7][8] and photoelectrode (PE) substrate. 7,[9][10][11][12][13] To gain flexible DSC, transparent polymer substrates are used with metal substrates. The preparation of efficient PEs with low temperature techniques required in the case of polymer substrate has proven out to be more difficult compared to that of CEs.…”

A new segmented cell design was applied to study the aging of dye solar cell with stainless steel (StS) photoelectrode substrate, in particular the role of electrolyte in the degradation. Photovoltaic showed changes in the recombination at the photoelectrode / electrolyte interface. With the segmented cell method, we confirmed that the electrolyte was not contaminated by the StS nor was it subject to other significant changes related to the rapid degradation.

“…Considering the work function of the metals, promising metal substrates for DSSCs are Ti, StSt, tungsten (W) and Zinc (Zn) [14] because the work function determine the contact types, i.e. ohmic contact or schottky contact.…”

“…For better attempts, instead of plastic film, previous study has proposed thin metal foil as a substrates. [14][15][16] A thin metal foil can be a excellent alternative to conductive-layer-coated plastic films, because temperature limitation due to substrate could be eliminated. Focusing on the characteristics of the interface between nano-sized TiO 2 and metal substrates, this chapter describes several effective methods for the high efficiency DSSCs based on metal substrates.…”
