Embodiment 1

[0029] The aerochromic control type semi-transparent polymer solar cell is prepared according to the following steps:

[0030] (1) Sonicate the ITO glass with acetone, ethanol, and deionized water for 30 minutes respectively, and then dry it with nitrogen for 30 minutes, as the cathode;

[0031] (2) Dissolve PFN in methanol solution to prepare a PFN-methanol mixed solution with a concentration of 1 mg / mL, and prepare a PFN-methanol-acetic acid mixed solution by adding 10 μL of acetic acid to each ml of PFN-methanol mixed solution , after stirring evenly, it is spin-coated on the cathode, the spin-coating speed is 3000rpm, and the spin-coating time is 40s to obtain a cathode buffer layer with a thickness of 3nm;

[0032] (3) Mix the donor material PTB7-Th with the acceptor material PC71BM to obtain a mixed material. The mass ratio of PTB7-Th to PC71BM in the miscible material is 1:1.5; chlorobenzene and 1,8-diiodooctyl Alkanes are mixed to obtain a mixed solvent, the volume pe...

Abstract

The invention relates to a gasochromic regulation and control type semitransparent polymer solar cell and a preparation method thereof. ITO conducting glass is taken as a cathode, poly[(9,9-di(3'-(N,N-dimethylamino)propyl)-2,7-fluorene)-2,7-(9,9-dioctylfluorene)](PFN for short)-methanol-acetic acid mixed solution is taken as a cathode buffer layer, a polymer mixed solution is taken as an active layer, WO3 is taken as an anode buffer layer, Ag is taken as an anode, and WO3/Pt is taken as a reaction layer. WO3 is taken as the anode buffer layer, the effect of collecting hole-blocking electrons is reached, the interface contact performance of the active layer and electrodes can be improved effectively, the transmittability from a hole to the anode is improved, and then the short circuit current density and power conversion efficiency of the device are improved; the WO3/Pt is taken as the reaction layer, and reacts with H2 to generate a blue tungsten bronze structure, so that the transmissivity of light can be coordinated effectively, and the absorptivity of light is strengthened.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric devices, in particular to an aerochromic control type translucent polymer solar cell and a preparation method thereof. Background technique [0002] Solar cells have many advantages, including: permanence—solar cells can be used to generate electricity as long as the sun exists; cleanliness—compared with thermal power generation, nuclear power generation, etc., solar power generation will not cause environmental pollution; flexibility—— Solar cells are suitable for medium-sized power stations as large as one million kilowatts, as small as power generation equipment for single-family residents. Existing solar cells such as crystalline silicon solar cells, multi-component compound thin-film solar cells, and nanocrystalline solar cells often have one or more defects such as high cost, complicated process, less material sources, and short battery life, while polymer solar cells (Polymer...
