Abstract

The invention relates to the field of photovoltaics, in particular to a photovoltaic flame retardance detection method. The method comprises the following steps: providing a detected part, wherein the detected part is a backboard part or a photovoltaic laminated part; performing laser etching on the detected part; and obtaining state information of the detected part in the laser etching process, and performing analysis according to the state information to obtain a detection result, wherein the state information comprises whether a fire breaks out or not. According to the photovoltaic flame retardance detection method, the state information is observed during laser etching, the production and processing processes can be combined together, and the detection effect is achieved, so that the photovoltaic flame retardance detection can be carried out on a production line; the processing and remoulding of the backboard part or the photovoltaic laminated part in the detection process are expectedly carried out, so that the backboard part or the photovoltaic laminated part is not damaged and the use of the backboard part or the photovoltaic laminated part is not influenced; and the backboard part or the photovoltaic laminated part can be fully inspected, so that the flame retardant property of each backboard part or photovoltaic laminated part is ensured and the potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cells, in particular to a method for detecting photovoltaic flame retardancy. Background technique [0002] Photovoltaic modules have certain requirements for flame retardancy in order to improve the safety performance of photovoltaic modules. Generally, the photovoltaic flame retardant test is to conduct a flame retardant test on the backsheet or photovoltaic laminate. The traditional photovoltaic flame retardant testing is generally the vertical combustion method or the inclined combustion method, but the above two methods are destructive tests, and the samples are scrapped after the test, and the above tests are all tested in the testing room, and there is no way to test on the photovoltaic production line . Since it is a destructive test, the photovoltaic flame retardant test is not a full test, but a random test, that is, only a small part is selected for testing. This does not really...
