A New Approach for Fabricating Low Cost DSSC by Using Carbon Ink From Inkjet Printer and Its Improvement Efficiency by Depositing Metal Bridge Between Titanium Dioxide Particles

Abstract

We report the fabrication of a dyesensitized solar cell (DSSC) using lowcost materials (carbon ink from an inkjet printer coated on glass as the counter electrode) and made by a combination of spray deposition and doctor blade methods. We noted that the efficiency of the DSSC with the carboncoated electrode (1.13%) was comparable to that with a platinumcoated counter electrode (1.16%). We also proposed an equivalent circuit for this solar cell. The value of the chargetransfer resistance was determined both experimentally and analytically, and we found that both approaches produced the same results. Moreover, we improved the efficiency of DSSC based carbon by depositing copper nanoparticle into the space between Titanium Dioxide (TiOv2) nanoparticle using electroplating methods.
