Embodiment 1

[0106] Embodiment 1: Preparation of thin-film solar cell substrate

[0107] The preparation of thin-film solar cell base tape is mainly through roll-to-roll continuous electroplating. The main steps are as follows:

[0108] The first step is to carry out continuous degreasing and water washing on the brass strip;

[0109] In the second step, the brass strip is continuously electroplated with nickel and washed with water;

[0110] The third step is to continuously electroplate copper on the nickel-plated brass strip and wash it with water;

[0111] The fourth step is to dry and coil the electroplated strip.

[0112] The thickness of the coating can be controlled by controlling the electroplating current and the time that the base tape stays in the electroplating tank by controlling the continuous tape speed to control the electroplating time, so as to achieve the purpose of controlling the thickness of the coating. For example, control the current density to 0.5A / cm 2 , T...

Abstract

The invention relates to a thin film solar cell as well as a base band and a preparation method thereof, in particular to a thin film solar cell base band. The thin film solar cell base band comprises a substrate layer, a diffusion impervious layer and a pure copper layer, wherein the substrate layer is made of alloy materials; the diffusion impervious layer is formed on the substrate layer; and the pure copper layer is formed on the diffusion impervious layer. The invention also relates to application of the thin film solar cell base band in preparing a solar cell, a thin film solar cell comprising the thin film solar cell base band, the thin film solar base band and a preparation method of the thin film solar cell. The thin film solar cell and the base band thereof have the advantages of thin thickness and good mechanical property without polluting functional layers.

Description

technical field [0001] The invention relates to a CIS thin-film solar cell, and also relates to a base band constituting the solar cell, and a preparation method of the base band and the CIS thin-film solar cell. Background technique [0002] Thin-film solar cells have attracted widespread attention due to their low production costs, low energy consumption, and high efficiency. Among the many preparation methods of thin-film solar cells, most of them use vacuum technology, such as magnetron sputtering and chemical vapor deposition. In the 1980s, a new non-vacuum method for preparing battery functional layers appeared in Germany. This technology continuously electroplates pure copper layer and pure indium layer on a 100-micron thick pure copper strip in a roll-to-roll manner, and vulcanizes the metal film layer at high temperature (500-600°C) to obtain CuInS 2 Semiconductor functional layers of solar cells. For example, US6,117,703 discloses a CIS solar cell based on coppe...
