Flexible solar power generation cell

Abstract

The invention relates to a flexible solar power generation cell which consists of a plurality of thin film cell units, a flexible substrate, a connecting circuit, a positive electrode and a negative electrode of the cell and a transparent protective film. The thin film cell units are grown on the flexible substrate by the methods of magnetron sputtering and chemical vapor deposition, produced by laser scribing and arranged like an array, the thin film cell units are connected in parallel and connected on the positive electrode and the negative electrode of the cell, and the transparent protective film is bonded on the surface of the solar power generation cell by heating. The thin film cell units consist of a plurality of thin film cell subunits, the structure of each subunit consists of the flexible substrate, a lower electrode, a solar power generation electrode, an upper electrode and the transparent protective film sequentially, and the upper electrodes and the lower electrodes of the adjacent subunits are series-connected by a printed circuit for constituting the thin film cell units. Gaps between the solar cell units and the thin film cell subunits are filled by protective insulating paint. The flexible solar power generation cell is significantly characterized by light weight, ability of winding and convenient carry and installation, and the structure with the combined series connection and the parallel connection can not only ensure a certain output voltage, but also not affect the overall situation when one part is damaged and prolong the service life of the cell.

Description

technical field [0001] The invention relates to a solar cell, in particular to a flexible thin-film solar power generation cell. Background technique [0002] With the increasing emergence of the energy crisis, human beings are more urgent to research on new energy sources. Among them, solar energy, which has the widest distribution and application prospects known to mankind, has attracted much attention. Solar heating and power generation have gradually entered the homes of ordinary people. At present, the general solid-state solar cells on the market are bulky, not foldable and bendable, so their applications in some special occasions are limited. Contents of the invention [0003] The invention provides a light-weight, portable, flexible and foldable thin-film solar power generation battery. [0004] The technical scheme that the present invention adopts in order to solve its technical problem is: [0005] A flexible solar power generation battery is composed of a plu...
