Embodiment Construction

[0024] Carry out the preparation of CdTe thin film solar cell according to the following preparation process:

[0025] (1) Pretreatment of the transparent glass substrate 1: use 1713 glass as the deposition substrate 1. Ultrasonic cleaning with acetone for 10 minutes to remove surface grease, and then ultrasonic cleaning with deionized water for 10 minutes to remove impurities on the glass surface; finally, the glass is dried and placed in a pretreatment chamber, and the glass substrate 1 is cleaned with plasma.

[0026] (2) Preparation of In 2 o 3 : F transparent conductive film 2: the transparent glass substrate 1 is transferred to the sample stage of the magnetron sputtering apparatus 9 by the mechanical arm 10, and the sputtering target material is high-purity In 2 o 3 . First use a vacuum pump to evacuate the sputtering chamber to 3Pa, then use a molecular pump to evacuate the reaction chamber to 1×10 -3 Pa. Infuse Ar gas and 5% CHF 3 , the flow rate is adjusted to...

Abstract

The invention discloses a preparation method of a CdTe film solar cell; a CdTe film adopts a near space sublimation method to prepare a CdS / CdTe cell on transparent conductive glass, a Ni back electrode is obtained by adopting magnetron sputtering. The preparation method comprises the following steps: firstly, carrying out transparent glass substrate pre-treatment; preparing an In2O3: F transparent conductive film; using the near space sublimation method to grow a CdS film on the prepared transparent conductive film; using the near space sublimation method to grow the CdTe film on the prepared CdS film, and using CdCl2 to carry out annealing treatment on the film to cause a CdS / CdTe interface to be recombined; using a magnetron sputtering instrument to sputter the Ni back electrode on the CdTe surface, and annealing to form ohm contact at high temperature; obtaining the effective CdTe film solar cell. In the invention, the magnetron sputtering instrument is connected with a near space subliming furnace by a gate valve, a magnetic manipulator is used to deliver samples, and the whole procedures are automatically finished under vacuum environment after the step that the glass substrate enters a pre-treatment chamber.

Description

Technical field: [0001] The invention relates to a manufacturing method based on CdTe thin-film solar cells, which belongs to the field of manufacturing inorganic compound energy materials. Background technique: [0002] With the growth of population and economy in today's world, the increasing scarcity of energy resources, the deterioration of the environment and the increasing demand for electric energy, the development and utilization of solar energy has set off an upsurge worldwide. This is very conducive to the sustainable development of the ecological environment and the benefit of future generations, so countries around the world are investing in research and development of solar cells. Solar energy is a clean, non-polluting, inexhaustible natural energy source. Almost all natural resources on which human beings depend are converted to solar energy. Direct conversion of solar energy into electrical energy is an important technology for large-scale utilization of solar...
