Thin film solar cell and manufacturing method thereof

Abstract

The invention relates to a thin film solar cell and a manufacturing method of the thin film solar cell. The thin film solar cell at least comprises a thin film solar cell panel and a degradable film, wherein the degradable film covers at least a part of the light receiving face of the thin film solar cell panel, and the degradable film is used for lowering the average light transmission rate of the thin film solar cell. The manufacturing method of the thin film solar cell includes the steps of providing the thin film solar cell panel, and forming the degradable film on at least a part of the light receiving face of the thin film solar cell panel. According to the thin film solar cell and the manufacturing method of the thin film solar cell, the use safety performance and the use efficiency of the thin film solar cell can be ensured, the problem that the excessive design is habitually required to deal with light recession can be solved, and therefore the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a thin-film solar cell and a manufacturing method of the thin-film solar cell. Background technique [0002] Due to the large consumption of traditional energy such as oil and its limited storage capacity, and its serious pollution to the environment, people pay more and more attention to clean energy such as wind energy and solar energy. In particular, solar energy has less geographical restrictions and is rich in energy. , has increasingly become a research focus and focus. [0003] Among them, thin-film solar cells can be manufactured using cheap glass, plastic, ceramics, graphite or metal sheets and other materials as substrates. The thickness of the film that can generate voltage is only a few microns, and the current conversion efficiency is as high as 13%. In addition to being flat, thin-film solar cells can be made into non-planar structures because of their flexibi...

AI Technical Summary

Problems solved by technology

[0010] In view of the above problems, in the actual application of thin-film solar cells in the prior art, overdesign of power, current and voltage is required. For example, the threshold power of cables or electric storage devices must be greater than the power P1. However, the output power of thin-film solar cells is not greater than P2 in most of the working hours

Excessive design will inevitably lead to more complex structures of related devices, thereby increasing the cost of thin-film solar cells

[0011] Since the early decline period of thin-film solar cells is generally several months, and the stable period of thin-film solar cells is at least several years or more than ten years, the over-design in response to the short-term early decline period essentially creates a waste of materials and equipment, and increase the overall cost of thin-film solar cells
