Abstract

In this paper, the suitable molecular weight of polyethylene glycol (PEG) and annealing temperature for dye-sensitized solar cells (DSSCs) anode was obtained by assessing the performance of DSSCs. The output current characteristic of the DSSCs is to explore factors that affect cell conversion efficiency and the effect of the mechanism. Experimental results show that the annealing temperature of 500°C and adding PEG of molecular weight 2000, the TiO2 thin film electrode TiO2 film electrode has good optical properties.

Summary

Introduction

The energy problem is the most restricting problem of current world economic development, solar energy as an inexhaustible, clean and pollution-free natural green energy, and becomes one of the most promising energies. Of currently solar cell research and application the most is silicon solar cell, but for the high cost of raw silicon cells, complex production process, improving efficiency potential is limited (the theoretical limit of the photoelectric conversion efficiency of 30%), limiting its civilian, in an urgent need of the development of low cost solar cell. In 1991, O’Regan et al [1] for the first time assembled photoelectric conversion efficiency of 7.1% - 7.9% of the DSSCs, and created a new field of solar cell research and development. (2014) Impact of Dye-Sensitized Solar Cell Anode Preparation on Performance. This paper introduced the preparation method of the anode of DSSCs, and the component parameters of two types of optical properties of anode effect are analyzed
