Apparatus and method for testing the macro and micro performance of solar cells by introducing light

Abstract

The invention relates to a device and a method for testing macroscopic and microcosmic performances of a solar battery through light introduction. A macroscopic and microcosmic performance test instrument for the solar battery is connected with a test box by light introduction equipment, the input end of the light introduction equipment is arranged in the macroscopic and microcosmic performance test instrument for the solar battery, the output end of the light introduction equipment is arranged in the test box, a solar battery sample is arranged below the output end of the light introduction equipment, a light response signal of the solar battery sample is connected with the macroscopic and microcosmic performance test instrument for the solar battery, and light irradiatometers are arranged in the macroscopic and microcosmic performance test instrument for the solar battery and the test box. Compared with the prior art, the device and the method have the advantages that a tested instrument environment is separated from a sample environment, the working principle of the solar battery under large-range change impact of the environment condition can be researched, and the instrument testing precision is not influenced.

Description

[0001] The invention belongs to the intersection field of new energy and instrument measurement, and in particular relates to a device and method for introducing light into and testing the macro and micro performance of solar cells. Background technique [0002] With the rapid development of society, human beings are consuming the limited energy on the earth at an alarming rate. Traditional energy sources such as oil, coal, and natural gas will be exhausted in the near future, and it is imminent to develop and utilize new energy sources. Inexhaustible and clean solar energy resources have brought a new dawn to mankind. Solar cells can directly convert light energy into electrical energy, which greatly facilitates human production and life. Solar photovoltaic power generation has developed rapidly in the past few decades, and the current global photovoltaic cell industry is growing rapidly. From 2010 to 2020, the annual growth rate of the global photovoltaic industry will reac...

Problems solved by technology

In the existing solar cell test, the sample must be fixed on the side of the light signal emitting end of the instrument to keep it parallel to the light signal and at a certain distance; in addition, each test must be tested on its corresponding instrument, and the sample must be tested when changing the test type. Change to the next instrument; at the same time, these precision testing instruments can only work in a certain environment, and the instrument will produce errors or even fail to work under the impact of changes in environmental conditions

Therefore, the contradiction between the solar cell performance testing instrument should be in a constant environment and the solar cell should be in a changing environment seriously restricts further research on the photoelectric conversion mechanism of the battery.
