Abstract: The preparation and properties of quasi-solid-state electrolyte films based on polyvinyl butyral were studied. The films were prepared by adding a pore forming agent and auxiliary agents to polyvinyl butyral. Factors affecting the preparation of the films were investigated. The results showed that the films prepared by adding 6.000 g calcium carbonate, 0.310 g calcium chloride, and 0.150 g glucose to 0.200 g polyvinyl butyral performed best. The impact of different pore ratios on device efficiency was investigated as well. The efficiency of dye-sensitized solar cells (DSSCs) using the quasi-solid-state electrolyte film reached 4.720% (open-circuit voltage Voc=0.7194 V, short-circuit current density Jsc=10.014 mA·cm-2, fill factor FF=0.6559), which was 88% of that for the corresponding liquid electrolyte solar cells. The film is easy to use for packaging and its preparation method is simple and non-toxic.
