Outdoor testing platform for intelligent solar cell pieces and testing method thereof

Abstract

The invention discloses an outdoor testing platform for an intelligent solar cell pieces and a testing method thereof. The outdoor testing platform comprises a solar cell piece support provided with a plurality of tested solar cell pieces, an intelligent topology circuit, an electronic load having a constant-current working mode and a constant-voltage working mode and a control circuit board having a constant-current working mode and a constant-voltage working mode. The tested solar cell pieces are encapsulated on the solar cell piece support through glass and ethylene vinyl acetate (EVA) adhesive films and connected with the intelligent topology circuit through interconnection strips, the intelligent topology circuit is connected to the electronic load, and the electronic load is connected with the control circuit board. The outdoor testing platform for the intelligent solar cell pieces and the testing method achieve shifting of independent testing and serial testing of the solar cell pieces through testing of an independent variable (IV) characteristic curve of the solar cell pieces and the intelligent topology circuit, acquired data are memorized in a large-capacity memory module of the platform and simultaneously sent to a remote monitoring computer through a wireless network, a working state of the solar cell pieces in an outdoor natural environment can be reflected really, and evaluation on the outdoor working performance of the solar cell pieces is achieved.

Description

technical field [0001] The invention relates to the field of solar cell testing, in particular to an outdoor testing platform for solar cells and a testing method thereof. Background technique [0002] With the rapid development of the domestic solar photovoltaic industry in recent years, the output of photovoltaic modules of various photovoltaic enterprises has increased year by year, and the testing requirements for cells and photovoltaic modules are also increasing. How to comprehensively and accurately measure the performance of the produced cells or modules, has become a crucial issue. [0003] At present, the test environment of solar cells and modules in domestic photovoltaic enterprises is mainly based on indoor solar simulators to measure and draw the IV characteristic curves of solar cells or photovoltaic modules. The advantage is that the irradiance and temperature can be controlled manually. The working environment of the module is required to facilitate testing...

Problems solved by technology

[0003] At present, the test environment of solar cells and modules in domestic photovoltaic enterprises is mainly based on indoor solar simulators to measure and draw the IV characteristic curves of solar cells or photovoltaic modules. The advantage is that the irradiance and temperature can be controlled manually. The working environment of the module is convenient for testing, but the disadvantage is that it cannot effectively reflect the real state of the module in an outdoor continuous working environment; therefore, it is increasingly necessary to test the outdoor IV characteristic curve of the battery or module on an outdoor test platform
