Recently, Hebei Hanguang Heavy Industry Co., Ltd. undertook the Handan City Science and Technology Research and Development Project "Dye-sensitized solar cell research and development" passed the meeting acceptance. The project has independently researched and developed ionic liquid electrolyte and electrode protective agent; optimized design of the conductive mesh of the battery has effectively controlled the gap of the solution layer; and the electrolyte is encapsulated by vacuum filling to improve the stability of the battery. The relevant departments tested: When the area of ​​the dye-sensitized solar cell was 100 cm?, the photoelectric conversion rate was 5.2%, the short-circuit current density was 11.2 mA/cm, and the open circuit voltage was 650 mV. This project carried out research work on dye-sensitized solar cell manufacturing process, preparation of titanium dioxide slurry, synthesis of electrolytic platinum solution, and synthesis of silver stripe protection agent, and prepared a large-area, high-performance dye-sensitized solar cell for industrialization. A good foundation will surely greatly promote the development of Handan City's science and technology and economy and society.
