 Abstract
A new type of dye-sensitized solar cell (DSC) based on a porous type Ti electrode without using a transparent conductive oxide (TCO) layer is fabricated for low-cost high-efficient solar cell application. The TCO-free DSC is composed of a glass substrate/dye-sensitized nanoparticle/porous Ti layer/electrolyte/Pt sputtered counter electrode. The porous Ti electrode (~350 nm thickness) with high conductivity can collect electrons from the layer and allows the ionic diffusion of through the hole. The vacuum annealing treatment is important with respect to the interfacial necking between the metal Ti and porous layer. The efficiency of the prepared TCO-free DSC sample is about 3.5% (ff: 0.48, : 0.64V, : 11.14 mA/).
