AI Technical Summary

Technical Problem

Existing perovskite solar cell testing equipment cannot be adapted to photovoltaic panels of different thicknesses and specifications. The clamping force is not adjustable, which may cause clamping damage or loosening of connections, affecting the accuracy and reliability of test data.

Method used

A testing device was designed, comprising a clamping block, a clamping connection assembly, and an adjustment assembly. The clamping force is automatically adjusted through the cooperation of the sliding seat and the rotating block, and the transmission line is fixed to prevent loosening through the design of the winding seat and the limiting wheel.

Benefits of technology

It achieves stable clamping of photovoltaic panels of different thicknesses, avoiding clamping damage and loosening of connections, improving the accuracy and reliability of testing, and reducing maintenance costs.

Abstract

The application relates to a controllable step IV curve testing device for a perovskite solar cell and relates to the technical field of IV curve testing of the cell. The device comprises a device main body, a mounting seat and a winding seat. Two clamping blocks are symmetrically and slidably arranged on the side wall of the mounting seat. A sliding seat is slidably arranged in the mounting seat. A clamping connecting assembly is arranged at the bottom of the clamping block. An adjusting assembly is arranged on the side wall of the sliding seat. The clamping block and the clamping connecting assembly are arranged to flexibly adjust the clamping force for the solar cell photovoltaic panel with different sizes and thickness specifications. The clamping force applied to the solar cell photovoltaic panel is adjusted according to the size of the solar cell photovoltaic panel. The sufficient clamping force required for stable connection is provided, and the solar cell photovoltaic panel is prevented from being squeezed and damaged by excessive clamping force. The winding seat, the sliding seat and the adjusting assembly are arranged to limit the position of the transmission line, resist external force pulling of the transmission line during use, and prevent problems such as loosening and welding-off of the connection.
