Abstract

The invention provides a photovoltaic module test sample and a performance evaluation method of a photovoltaic module, and belongs to the field of solar cells. A battery string in the test sample comprises a first battery piece and a second battery piece which are distributed side by side; one end, close to the second battery piece, of the first battery piece is a battery piece first end, and one end, close to the first battery piece, of the second battery piece is a battery piece second end; the battery piece first end and the battery piece second end are overlapped, and an inter-piece gap is formed between the battery piece first end and the battery piece second end; wherein the test sample comprises a temperature-resistant separator, and the temperature-resistant separator seals one of the openings at the two ends of the inter-sheet gap. The evaluation method comprises the following steps: preparing the test sample for lamination, then splitting to expose the to-be-tested surface surrounding the inter-sheet gap, obtaining the glue film permeation amount by measuring the glue overflow area of the to-be-tested surface, and judging the performance of the photovoltaic module according to the glue film permeation amount, so that the period can be effectively shortened, and the cost can be effectively reduced.

Description

technical field [0001] The present application relates to the field of solar cells, in particular, to a test sample of a photovoltaic module and a method for evaluating the performance of the photovoltaic module. Background technique [0002] In the production of photovoltaic modules, product performance is usually evaluated to provide directions for the improvement of the production process. [0003] Currently, PV modules are usually fabricated and evaluated for reliability testing. However, the method of manufacturing photovoltaic modules to test the reliability has a long period and high cost. Contents of the invention [0004] The purpose of this application is to provide a photovoltaic module test sample and a method for evaluating the performance of photovoltaic modules, which can effectively shorten the cycle time and reduce the cost by judging the performance of the photovoltaic module according to the amount of adhesive film penetration. [0005] The embodiment ...
