Embodiment 1
[0061] Using chlorobenzene as a solvent, the P3HT:PCBM mixed solution with a concentration of 18 mg / ml and PCBM accounting for 44% of the total mass was heated and stirred at 60°C for 3 hours, then stopped heating and continued to stir for 12 hours.
[0062] The ITO anode layer 2 and the glass substrate 1 form an ITO conductive glass, and the etched strip-shaped ITO conductive glass with a certain width is cleaned and dried. Place the clean ITO glass on the bracket of the spin coating machine, apply the PEDOT:PSS solution evenly to the entire sheet through a 0.45 micron filter head, and rotate at a speed of 3000 rpm for one minute to make the PEDOT:PSS on the ITO surface A thin film with a thickness of 40 nanometers was formed as the anode modification layer 3 and heated in an oven at 120° C. for 30 minutes.
[0063] Transfer the baked ITO substrate coated with PEDOT:PSS to the glove box, place it on the spin coater bracket after the substrate is cooled, and evenly coat the st...
Embodiment 2
[0068] With chlorobenzene as solvent, the concentration is respectively 10 mg / ml and 20 mg / ml, and the quality of PCBM accounts for 40% and 80% of the total mass of P3HT:PCBM mixed solution heated and stirred at 60 degrees for 3 hours, stop heating and continue Stir for 12 hours.
[0069] The ITO anode layer 2 and the glass substrate 1 form an ITO conductive glass, and the etched strip-shaped ITO conductive glass with a certain width is cleaned and dried. Place the clean ITO glass on the bracket of the spin coating machine, apply the PEDOT:PSS solution evenly to the entire sheet through a 0.45 micron filter head, and rotate at a speed of 5000 rpm for one minute to make the PEDOT:PSS on the ITO surface A thin film with a thickness of 20 nanometers was formed as the anode modification layer 3 and heated in an oven at 120° C. for 30 minutes.
[0070] The baked ITO substrate coated with PEDOT:PSS is transferred to the glove box, and after the substrate is cooled, it is placed on ...
Embodiment 3
[0075] With chlorobenzene as solvent, the concentration is respectively 10 mg / ml and 20 mg / ml, and the quality of PCBM accounts for 40% and 80% of the total mass of P3HT:PCBM mixed solution heated and stirred at 60 degrees for 3 hours, stop heating and continue Stir for 12 hours.
[0076] The ITO anode layer 2 and the glass substrate 1 form an ITO conductive glass, and the etched strip-shaped ITO conductive glass with a certain width is cleaned and dried. Place the clean ITO glass on the bracket of the spin coating machine, apply the PEDOT:PSS solution evenly to the entire sheet through a 0.45 micron filter head, and rotate at a speed of 1200 rpm for one minute to make the PEDOT:PSS on the ITO surface A thin film with a thickness of 100 nanometers was formed as the anode modification layer 3 and heated in an oven at 120° C. for 30 minutes.
[0077] The baked ITO substrate coated with PEDOT:PSS is transferred to the glove box, and after the substrate is cooled, it is placed on...
