Problems solved by technology

[0003] On the one hand, the current transparent perovskite solar cells generally use magnetron sputtering and other technologies when preparing transparent electrodes, which is easy to cause certain damage to the carrier transport layer and perovskite active layer during the production process, affecting the product quality. service life and production yield; on the other hand, in order to ensure the conductivity between the transparent electrode and the carrier transport layer, it is generally necessary to use higher-priced commercial products in the prior art, such as ITO and FTO, which will greatly Increase the preparation cost of transparent perovskite solar cells, which is not conducive to the popularization of products; if the transparent electrode is made of lower-cost materials, the contact resistance between the transparent electrode and the carrier transport layer will be large due to the problem of material characteristics , leading to low electrical efficiency of the product, which is not conducive to practical use
