Abstract

The invention discloses a film photovoltaic device with the air purification treatment function, and aims at providing the film photovoltaic device which can achieve photovoltaic power generation andhas the air purification treatment function. The device comprises a substrate layer, a photovoltaic film layer and a base layer, a transparent photocatalyst layer is arranged on the lower surface of the substrate layer, the photovoltaic film layer is arranged on the upper surface of the base layer, and an air passage with an opening formed in one side or two openings formed in two sides is arranged between the photocatalyst layer and the photovoltaic film layer. Accordingly, on the basis of a function layer of conventional film photovoltaic, by additionally arranging the photocatalyst layer and the air passage, and meanwhile the dual functions of the photovoltaic effect and air purification are achieved.

Description

technical field [0001] The present invention relates to the field of photovoltaic technology, and more particularly, to a thin-film photovoltaic device with an air purification function. Background technique [0002] Human survival is inseparable from air, and the quality of air directly affects human health and life safety. Today, the environment is deteriorating and pollution is increasing, and the air quality is getting worse and worse. The so-called indoor air pollution refers to the indoor environmental pollution behavior that causes harmful substances in the indoor air to exceed the standard due to various reasons, thereby affecting human health. Harmful substances include bacteria and viruses, inhalable particulate matter, and volatile organic pollutants (VOCs) such as formaldehyde, benzene, ammonia, and radioactive oxygen. With the improvement of people's awareness of environmental protection, the air quality of the living environment gradually has high requirement...
