As a dielectric barrier, it can be placed between a metal or glass substrate and CIS (copper indium sulfide) or CIGSE (copper indium gallium selenide) photovoltaic structures to provide insulation and barrier, prevent leakage between electrodes, and improve the performance and stability of the battery.
For preparing the packaging layer: the film made of polysilazane can be used as the packaging layer of solar cells, which has good anti-aging property, can enable the chalcopyrite based solar cells to have appropriate reflectivity in specific light bands, can protect the internal structure of the battery from the erosion of external environment such as water, oxygen, etc., and extend the service life of the battery.
Making anti glare film: It can be used to prepare anti glare film for solar cells, with appropriate anti glare surface texture, and can effectively remove surface pollution, reduce light reflection, increase the amount of light incident, and thus improve the absorption efficiency of solar cells for light.
As a passivation layer: The SiOxNy layer formed by the solidification of fully hydrogenated polysilazane thin film can be used as a passivation layer for organic solar cells. It can passivate the defects on the surface of the battery transport layer, reduce the recombination of photo generated carriers, induce the preferential accumulation of non fullerene acceptors near electronic contact, facilitate charge extraction, thereby improving the photocurrent density and power conversion efficiency of the battery, and also extend the service life of the battery.
Acting as a strain compensation layer: Organic polysilazane (OPSZ) can be used as a strain compensation layer for perovskite solar cells. A large number of Si-N and Si-H bonds can be anchored on the surface of perovskite, providing a hydrophobic environment to improve water resistance. At the same time, their spontaneous shrinkage characteristics during cooling are utilized to regulate the stress state of perovskite films, improve the phase stability of perovskite, and ensure the stability and photoelectric conversion efficiency of the device.
Preparation of optical films: Polysilazane can be used to manufacture optical films by combining with modified raw materials to form composite materials that can be used for optical film preparation, in order to adjust optical properties and improve the absorption and utilization efficiency of solar cells for different wavelengths of light.
