Solar cell assembly and detection method

Abstract

The invention discloses a construction and detection method of a solar cell. The method comprises the following processing steps of 1, constructing the solar cell by material selection, structural processing and battery package; 2, performing aging test on the solar cell on the condition that irradiation strength is between 600w / m<2> and 1,000w / m<2>; 3, performing shaping test on the solar cell, and acquiring an open-circuit voltage temperature correction factor, a short-circuit current temperature correction coefficient, a nominal working temperature and performance under low irradiance of the solar cell; 4, performing metrological performance test on the solar cell, wherein the metrological performance test comprises spectral response test, quantum efficiency test and I-V characteristic measurement, and the spectral response test comprises repeatability test and stability test; and 5, calibrating and assigning the solar cell according to each test result, and performing uncertainty analysis. By testing the constructed solar cell and calibrating and assigning the solar cell, the performance detection can be effectively performed on the solar cell.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a solar cell assembly and detection method. Background technique [0002] Solar cell testing plays an important role in the research and development, production and sales of solar cells, and the measurement results of electrical properties are the standard for evaluating the advanced production process of solar cells, and also the basis for pricing solar cells into the sales field. [0003] At present, the mainstream technology is still traceable to the standard test conditions (ie STC) by means of standard solar cells or standard solar cell components. During the test, the existing measurement methods only test the input characteristics, output characteristics and conversion efficiency of solar cells. However, , There are many factors affecting the performance and stability of solar cells in solar cells, such as light aging performance, various coefficients of shaping, repeatability an...
