Problems solved by technology

However, because polymer materials are generally not resistant to high temperatures and cannot be heat-treated at higher temperatures, how to improve the crystallization properties of solar cell films and the bonding force between the substrate and the film will be the difficulty of flexible DSCs.
[0003] Polymer substrates cannot withstand high temperature sintering at around 500°C

Abstract

The invention provides a method for preparing a dye sensitized solar cell photo-anode at low temperature. The method comprises the following steps of: firstly, dispersing first titanium dioxide composite powder into isopropyl alcohol, subjecting to ultrasonic wave treatment, and then adding polyethylene glycol to obtain a precursor A; weighing and dispersing second titanium dioxide composite powder with different particle diameters of the first titanium dioxide composite powder into a titanium dioxide sol, and subjecting to ultrasonic wave treatment to obtain a precursor B; mixing the precursors A and B, and then subjecting to ultrasonic wave treatment to obtain reaction liquid; placing the reaction liquid and a substrate together into a reaction kettle to seal, setting the electrophoresis voltage and the electrification time of the reaction kettle after the temperature is stabilized, carrying out electrophoretic deposition, forming a layer of film on the substrate after the electrophoretic deposition is completed, carrying out thermal treatment on the substrate adhered with the film, and drying the substrate; and finally subjecting to ultraviolet treatment.

Description

technical field [0001] The invention belongs to the field of new material technology and new energy technology, and relates to a low-temperature preparation method of a photoanode of a dye-sensitized solar cell. Background technique [0002] The biggest difference between flexible dye-sensitized solar cells and traditional dye-sensitized solar cells lies in the different substrates. Traditional dye-sensitized solar cells are generally made of hard materials such as conductive glass and ceramics. Such materials can withstand higher sintering temperatures, which is beneficial to the heat treatment of solar cells, but the application range of the cells after commercialization is limited. The substrate of flexible solar cells is a polymer conductive film, such as PET film, so it has relatively good flexibility, and can even be made into a rollable solar cell. However, because polymer materials are generally not resistant to high temperatures and cannot be heat-treated at highe...
