Fabrication and characterization of interconnected grid-type dye-sensitized solar modules

Abstract

A process is developed for the fabrication of interconnected grid-type dye-sensitized solar cell (DSSC) module by using commercially available materials. This novel structure not only demonstrates high current output, but also exhibits high open circuit over 1 volt. In addition, the fabrication process is simple in that it allows the fabrication of a normal grid-type DSSC module with only the addition of a laser isolation treatment during substrate preparation. Finally, interconnected grid-type DSSC modules with 1.41V open circuit voltage and 5.86% conversion efficiency equal to 261.7mW power output was achieved for a low-volatility electrolyte system under a simulated 1 sun irradiation on a 12cm by 7.5 cm substrate.
