Embodiment 1
[0041] Etching and cleaning of ITO conductive glass:
[0042] First put the ITO conductive glass (size is 3×3cm 2 , ≤15Ω / □) with hydrochloric acid and Zn powder with a concentration of 6mol / L to etch the ITO layer into four strips of 16×4mm 2 The thin strips were ultrasonically cleaned with acetone, isopropanol, and ultrapure water for 5 minutes in sequence, and then dried with dry nitrogen to obtain etched ITO conductive glass deposition for later use.
[0043] TiO 2 Preparation of nanostructured films:
[0044] Mix absolute ethanol, n-butyl titanate, and glacial acetic acid at a volume ratio of 4:1:0.1 to prepare uniform, colorless, and transparent TiO 2 Sol precursor. 150 μL of TiO 2 The sol precursor liquid is dropped on the etched ITO conductive glass, and spin-coated (2000 rpm, 30 seconds) to obtain TiO 2 Sol film; the TiO 2 After the sol film was stored at room temperature in a humidifier with a relative humidity of 50% for 12 hours, it was placed in an air-atmos...
Embodiment 2
[0052] Preparation of PTB7-th:ITIC blend films:
[0053] Using chlorobenzene as a solvent, prepare a solution of PTB7-th: ITIC with a total concentration of 10 mg / mL at a ratio of 1:1, and stir at 40°C for 12 hours to obtain a PTB7-th: ITIC blended chlorobenzene solution; Li PTB7-th:ITIC blend solution uniformly dispersed in TiO 2 - on the CdS heterojunction thin film layer, and then spin coating (1500 rpm, 60 seconds) to deposit the polymer onto the TiO 2 - On CdS heterojunction films; heat treatment at 100 °C for 10 min in a nitrogen-protected glove box to make the polymer and TiO 2 -CdS heterojunction film with sufficient contact.
[0054] In addition, the PTB7-th: ITIC blend film, PTB7-th film and ITIC film were prepared on the glass substrate with the same spin-coating method by the same method for testing their basic photophysical properties; , the concentration of the chlorobenzene solution of PTB7-th and ITIC used is also 10mg / mL.
