Abstract

A dye-sensitized solar cell quasi solid electrolyte and a method for preparing a solar cell by using same are disclosed. The dye-sensitized solar cell quasi solid electrolyte comprises, by weight, 2-30% of alpha-cyanoacrylate, 0.1-10% of an inorganic additive, 5-20% of iodide, 0.5-5% of iodine, 10-50% of plasticizer, 0.5-10% of a photoanode compounding ingredient and 10-30% of an organic solvent.The quasi solid electrolyte of the invention has good heat stability, good mechanical properties, high conductivity, a fast gel speed and low costs. The electrolyte is easy to be prepared and to realize industrialization production. A liquid electrolyte is easy to leak, difficult for packaging and possesses other problems. The above problems can be radically solved by using the quasi solid electrolyte.

Description

[0001] technical field

[0002] The invention belongs to a preparation technology of a quasi-solid electrolyte, in particular to a quasi-solid electrolyte applied to a dye-sensitized solar cell and a method for preparing a solar cell by using the same.

[0003] technical background

[0004] Nowadays, problems such as environmental pollution, greenhouse effect, and energy crisis are becoming more and more serious in the world. People's demand for renewable energy continues to increase. As a kind of green energy, solar energy has been widely concerned by people. Solar cells are one of the most efficient ways to harness solar energy. Dye-sensitized solar cells (DSSCs) show great promise as an inexpensive unconventional solar cell compared with conventional p–n junction solar cells.

[0005] Although the traditional DSSC composed of liquid electrolyte has high photoelectric conversion efficiency, there are many problems due to the liquid electrolyte, for example: 1. The orga...
