Film solar cell impedance rapid diagnosis system and method

Abstract

The invention discloses a film solar cell inter-module impedance rapid diagnosis system and method. A sensor assembly is arranged above a film solar cell, the sensor assembly is connected with an impedance test module, the impedance test module is separately connected with a controller and a power drive part through a data communication interface, a manipulator transmission mechanism is connectedbetween the power drive part and the sensor assembly, the sensor assembly comprises n sensor groups, each sensor group contains m sensors; the impedance of n*(m-1) adjacent film solar cell modules inthe controller is calculated and diagnosed; the diagnosis system and method of the invention lead the metal sensor contact to stably contact with the lead of the film solar cell and avoid the damage of the manipulator transmission mechanism caused by the impact force to the lead of the film solar cell when in work; the work pattern--serial and parallel coexistence is adopted so as to ensure the rapidity of the diagnosis work and avoid the high cost of fully parallel work pattern; and the controller and the manipulator transmission mechanism are used to realize the complete automatization of the diagnosis.

Description

technical field [0001] The invention relates to a system for rapid diagnosis of impedance between solar thin film cells. Background technique [0002] In the production process of solar thin-film cells, since the cutting of solar thin-film cells is realized by laser processing, it is inevitable that the impedance between solar thin-film cells will be inconsistent during the processing, and even a short circuit may occur. At present, in the solar thin film battery production line, a multimeter is used to manually detect n groups of batteries, which is cumbersome and easy to be negligent and cause missed inspections. Contents of the invention [0003] The purpose of the present invention is to provide a fast diagnostic system for inter-battery impedance used in solar thin-film battery production lines, which can quickly and automatically collect the resistance value between n batteries, judge the fault and determine the location of the fault, and record the resistance value ...
