Perovskite solar cell quantum efficiency test fixture

Abstract

The invention discloses a perovskite solar cell quantum efficiency test fixture, and belongs to the technical field of solar cell test fixtures. The device comprises a base which is provided with a first light hole; the fixing assembly is connected with the base and provided with a first storage area, when the solar cell is placed in the first storage area, a contact area of the solar cell is erected on the base, and an illumination area of the solar cell covers the first light hole; and the positioning frame is connected with the fixing assembly, the positioning frame is provided with a second storage area, and when the circuit board is placed in the second storage area, the circuit board is in contact with each contact on the contact area of the solar cell. In the actual operation process, the position of the solar cell can be fixed only by placing the solar cell in the first storage area, at the moment, the position of each contact of the solar cell is the same as the test position of the standard tester, the same irradiance is ensured, the operation is simple and convenient, the test repeatability is good, and the test efficiency is high. And the previous test result can be reproduced through multiple measurements.

Description

technical field [0001] The invention belongs to the technical field of solar cell test fixtures, in particular to a perovskite solar cell quantum efficiency test fixture. Background technique [0002] Perovskite solar cells are a new type of optoelectronic device developed in recent years. After just over a decade of development, its photoelectric efficiency has reached a level that competes with silicon-based solar cells and thin-film solar cells that have been commercialized for many years. It is a very promising optoelectronic device. The characterization of its optoelectronic properties mainly includes solar cell J-V performance test and quantum efficiency test. Among them, quantum efficiency test can characterize the response of solar cells to incident spectrum, mainly reflected in the onset and cutoff wavelengths of light absorption, and in the spectral range. The integral current and other parameters are an important means of characterization of optoelectronic proper...

Problems solved by technology

When comparing, in order to ensure that the irradiance of the sample to be tested is the same as that of the detector, the relative position of the sample to be tested and the detector needs to be the same. However, in the current commercial quantum efficiency test system, the fixture generally matches the silicon-based solar energy. The size of the battery, and its relative position is difficult to adjust and fix

[0004] That is to say, at present, when testing the quantum efficiency of perovskite solar cells, it is difficult to accurately locate due to the lack of special fixtures, which makes it impossible to guarantee that the perovskite solar cells and the tester have the same testing position, and thus cannot guarantee the same quantum efficiency. Irradiance, there are important problems such as large deviation of test results and poor repeatability
