Description

technical field

[0001] The invention relates to the technical field of solar cells, in particular to a dense layer obtained from a silver / titanium dioxide nanocomposite material and a perovskite solar cell with a silver / titanium dioxide nanocomposite dense film. Background technique

[0002] At present, the field of solar cells is developing rapidly. Compared with the existing solar cell technology, perovskite materials and devices have several advantages. Perovskite materials have strong light absorption ability, high extinction coefficient, and excellent carrier transport characteristics. , can be prepared at low temperature, etc., so it is a very excellent photovoltaic material that absorbs sunlight. At the same time, due to its special plasmonic effect, silver particles can form resonance with incident photons in a certain frequency range of incident light, and greatly Enhance the absorption of light.

[0003] At present, perovskite solar cells based on carbon counter e...
