Embodiment Construction

[0019] The solar cell test system can control the switch of the solar simulator according to the test time, and read the real-time current, voltage and corresponding temperature and spectrum measurement values ​​of the solar cell through the sampling circuit, temperature sensor and data acquisition card (DAQ). After numerical calculation and processing by computer, the I and V values ​​close to the standard test conditions are obtained, so as to draw the I-V characteristic curve close to the standard test conditions, and calculate the filling factor, photoelectric conversion efficiency and other parameters.

[0020] In order to realize the above functions, the solar cell testing system in this embodiment is composed of a PCI-9111 series data acquisition card (DAQ) produced by ADLINK, an X86 compatible computer, an infrared spectrometer produced by Nicolet and a domestic short-arc xenon lamp system. The solar cells tested are standard cells (SANYO ELECTRIC CO.LTD, condition: AM1...

Abstract

The invention relates to a reproduction-function solar cell test system, which is composed of a solar ray simulator, a data collection system and a data processing system. The invention is characterized in that the data collection system can read real-time current, voltage, corresponding temperature parameters and spectral measurement values of a solar cell and transmit the data to the data processing system; the data processing system receives the data from the data collection system to process the data and finally completes the reproduction of IV values under a standard state. The system can introduce an automatic reproduction system by a mode of software upgrading on an original test hardware platform, effectively and reliably overcomes the defect of spectral mismatch of the original test hardware platform, avoids waste of funds and resources brought by upgrading the hardware platform, and has high cost performance.

Description

technical field [0001] The invention relates to a semiconductor material testing method, in particular to a solar cell testing system with reproducible functions. Background technique [0002] In the 21st century, solar cell power generation is in a prominent position with remarkable results. In the wide application of solar photovoltaic power generation systems, reflected in the commercialization of solar cell power generation technology, the following two points are particularly important: [0003] 1. The improvement of the efficiency of solar cell products, so the research and testing of the conversion efficiency of the solar cell itself is a research field worthy of attention; [0004] 2. Diversification of solar cell products, such as amorphous silicon thin film cells, monocrystalline silicon cells and new HIT cells. Therefore, it is of great practical significance to study a high-precision and general-purpose solar cell testing system. [0005] Usually, testing the ...
