Problems solved by technology

However, its preparation cost is relatively expensive (for example, indium in ITO is a rare metal, and ITO, FTO, and AZO metal oxide transparent conductive electrodes are usually prepared by magnetron sputtering)
For this reason, people try to replace metal oxide transparent conductive electrodes with materials such as conductive polymers, nano-metal wires, graphene, and metal grids. Although good results have been achieved, compared with metal oxide transparent conductive electrodes, , there are still some differences in device performance

Abstract

The invention discloses a method for recycling a transparent conductive electrode of an organic solar cell. The method is characterized by comprising the following steps: putting a waste organic photovoltaic device into an organic solvent to remove a top electrode, an interface material and a photoactive layer of the device; putting the device into a dilute acid solution to remove the residual metal electrode and interface material so as to obtain a recyclable metal oxide type transparent conductive electrode; and preparing an organic photovoltaic device by taking the recyclable metal oxide type transparent conductive electrode as a bottom electrode. According to the method, the metal oxide type transparent conductive electrode is recycled from the used photovoltaic device for multiple times, so that the problems of indium scarcity in ITO and high price are solved, re-preparation of the bottom electrode is avoided, and the material cost and the preparation cost are reduced. Under the same preparation condition, the prepared cell device achieves photoelectric conversion efficiency exceeding that of the device under the first use condition, and the stability of the cell device is notinfluenced.

Description

technical field [0001] The invention belongs to the technical field of organic photovoltaic devices, and in particular relates to a method for recycling transparent conductive electrodes of organic photovoltaic devices. Background technique [0002] As a new type of energy device, polymer solar cells have unique advantages in wet processing, large area and flexibility. Recently, polymer solar cells have made important breakthroughs in energy conversion. It has been reported that the efficiency of such cells has exceeded 16%, reflecting a good application trend. However, compared with commercial silicon-based solar cells, polymer solar cells still have a large gap in terms of photoelectric conversion efficiency, device stability, and service life. Therefore, in order to expand its application, in addition to strengthening the research work in these three aspects, work should also be carried out on the optimization of device preparation and cost control. In traditional polym...
