Embodiment 1
[0040] Take 0.28g of Z991 (purity is 93%, provided by the Green Photoelectric Conversion Technology Project R&D Department of Shanghai Institute of Ceramics, Chinese Academy of Sciences) dissolved in a mixed solvent of acetonitrile and tert-butanol (1 / 1, volume ratio), fully stirred Let it dissolve completely. Then add 0.022g DPA (co-adsorbent) and stir to form a 1L homogeneous mixed solution containing Z9910.2mM and DPA0.1mM after completely dissolving.
[0041] TiO in dye-sensitized solar cells 2 After the electrodes were printed on the surface of FTO by screen printing, they were sintered at 500 °C, Til 4 After processing and continuing to sinter, soak in the dye solution as described above for 48 hours, remove and clean with acetonitrile for later use. In the battery assembly, carbon is used as the counter electrode, and the electrolyte solution composed of ionic liquid, iodine and solvent is used, and a complete dye-sensitized solar cell can be assembled by standard met...
