Embodiment 1

[0012] This embodiment describes a method for accelerating and stabilizing the maximum power of a cadmium telluride thin-film solar module. First, an external current is applied to the solar module, and the current is 1 times the short-circuit current. The module is illuminated with 1000 W / m2 until the maximum power is stable. The light source can be xenon lamp, metal bonded lamp, halogen lamp, outdoor light source. The time for maximum power to stabilize is shortened from 30 minutes to 10 minutes.

Embodiment 2

[0014] This embodiment describes a method for accelerating and stabilizing the maximum power of a cadmium telluride thin-film solar module. First, an external current is applied to the solar module. The current is twice the short-circuit current. The external current lasts for ten minutes, and then the solar module is Carry out 1000 W / m2 illumination until the maximum power reaches stability. The light source can be a xenon lamp, a metal bonded lamp, a halogen lamp, or an outdoor light source. The time for maximum power to stabilize is shortened from 30 minutes to 10 minutes

Embodiment 3

[0016] This embodiment describes a method for accelerating and stabilizing the maximum power of a cadmium telluride thin-film solar module. First, an external current is applied to the solar module. The current is 0.5 times the short-circuit current, and the external current lasts for 30 minutes. The module is illuminated with 1000 W / m2 until the maximum power is stable. The light source can be xenon lamp, metal bonded lamp, halogen lamp, outdoor light source. The time for the maximum power to stabilize is shortened from the original 30 minutes to 15 minutes,

Abstract

The invention belongs to the field of thin film solar energy, and particularly relates to a method of acceleratively stabilizing the maximal power of a CdTe thin film solar module. Current which is 0.5 to 2 times of the short circuit current of the solar module is externally added to the CdTe thin film solar module, and the duration time is 2 to 30 minutes. The method can effectively and acceleratively stabilize the maximal power of the solar module, and thus the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of thin-film solar energy, and in particular relates to a method for accelerating and stabilizing the maximum power of a cadmium telluride thin-film solar module. Background technique [0002] A solar module is basically composed of solar cells connected in series and in parallel with a circuit structure. The circuit structure is encapsulated in two substrates. The substrate material can be glass, stainless steel, or polymer, and at least one side is transparent. , the sunlight enters the solar cell from the light-transmitting substrate, and the solar cell structure in the module consists of a transparent conductive electrode, a semiconductor p-n junction (p-n junction), and a back electrode, in which the semiconductor p-n junction is close to the transparent electrode. The side is an n-type semiconductor, and the p-type semiconductor is an absorber layer. [0003] The incident light is absorbed by the absorbing laye...
