The invention provides a flexible packaging film with a photovoltaic characteristic and a secondary battery. The flexible packaging film with the photovoltaic characteristic comprises a photovoltaic thin film layer, an insulating protective layer and a heat sealing layer, wherein the insulating protective layer is arranged on the upper surface of the heat sealing layer, and the photovoltaic film layer is arranged on the upper surface of the insulating protective layer; the photovoltaic thin film layer comprises N photovoltaic thin film units, each photovoltaic thin film unit comprises a substrate and a photovoltaic thin film subunit arranged on the upper surface of the substrate, and N is greater than or equal to 1. The flexible packaging film with the photovoltaic characteristic can be used for effectively packaging the battery cell, and enables the secondary battery to have the photovoltaic characteristic, so that the portability of a solar energy-secondary battery integrated systemis effectively improved, the high-quality secondary battery with a self-charging function can be obtained, and the cruising ability of a direct-current power device is improved.
Description
technical field [0001] The invention relates to a flexible packaging film with photovoltaic properties, in particular to a flexible packaging film with photovoltaic properties and a secondary battery, belonging to the technical field of energy. Background technique [0002] As a sustainable clean energy, solar energy is an ideal renewable energy. Among them, the characteristics of solar photovoltaic is an important form of solar energy utilization, specifically, an energy conversion form that directly converts the sun's light energy radiation into electrical energy. At this stage, photovoltaic characteristics have received more and more attention and application. [0003] At this stage, the use of solar cells as a power supply source for lithium-ion batteries has become one of the development directions of lithium-ion batteries. For example, lithium-ion batteries, solar cells, LED lights and other related components are fixed through the external casing to form a complete ...
