Problems solved by technology

However, since traditional fibrous polymer solar cells use evaporation or electrochemical complex preparation processes, the way the two electrodes are wound greatly limits its light-absorbing area, so the weaving and scaling of fibrous polymer solar cells greatly limits its Application and Development in Wearable Devices

Abstract

The invention belongs to the technical field of solar cells, and particularly discloses a polymer solar cell fabric and a preparation method thereof. A titanium wire coated with a nanometer zinc dioxide layer is taken as a negative electrode, the negative electrode is coated with an active layer and a hole transport layer respectively through a pulling and dip-coating method, and finally knittingis carried out by taking the coated titanium wire and a cotton thread as warp threads and a silvering nylon multifilament and a cotton thread as weft threads so as to form the flexible and ventilatedpolymer solar cell fabric. The photoelectric conversion efficiency of the single polymer solar cell in the fabric can reach 1.62%. The open-circuit voltage of five series devices can be 2.1 V by adjusting the number of polymer solar cells knitted into the fabric, and the short-circuit current of five parallel devices is 0.23 mA. The preparation technology is simple and low in cost, the prepared product is high in flexibility and good in ventilation, and the fabric can be applied into daily life of people as a portable power supply device for clothes.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a polymer solar cell fabric and a preparation method thereof. Background technique [0002] With the rapid development of wearable electronics, the demand for sustainable and flexible energy devices is increasingly urgent. Flexible solar cells capable of harvesting clean and renewable solar energy have shown great potential in the field of wearable electronics. Among all types of solar cells, polymer solar cells have the advantages of light weight, low cost, and good flexibility. Polymer solar cells are usually made into thin films to achieve flexibility. However, strictly speaking, thin film devices can only be bent and cannot be twisted in three-dimensional space, and may be deformed and ruptured during use as a wearable device. In recent years, woven fibrous polymer solar cells have unique advantages in wearable electronics due to their superior three-dimensi...
