Anti-PID (potential Induced Degradation) photovoltaic module

Abstract

The invention provides an anti-PID (potential Induced Degradation) photovoltaic module, which comprises an ultra clear glass layer, a first anti-PID packaging layer, a first EVA film layer, a solar cell layer, a second anti-PID packaging layer, a second EVA film layer, a third anti-PID packaging layer and a backplane layer overlapped sequentially from bottom to top, wherein both the first anti-PID packaging layer and the second anti-PID packaging layer have a box structure; the first EVA film layer is located in the first anti-PID packaging layer and the first anti-PID packaging layer is packaged around the first EVA film layer; the second anti-PID packaging layer is located in the second EVA film layer and the second anti-PID packaging layer is packaged around the second EVA film layer; the third anti-PID packaging layer is overlapped on the second EVA film layer; and the third anti-PID packaging layer is laid at the position of a leading-out wire of the backplane layer. The above anti-PID photovoltaic module has good anti-PID performance.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to an anti-PID photovoltaic module. Background technique [0002] As a kind of renewable green energy, solar energy has gradually developed rapidly all over the world. Solar photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light into electrical energy. After solar cells are connected in series, they are protected by glass, packaging materials and backplanes, and finally filled with silica gel. Encapsulate to form a large-area photovoltaic module. [0003] PID (potential Induced Degradation, Potential Induced Degradation) is a characteristic of photovoltaic modules, which refers to the phenomenon that the output will drop when high voltage flows through the solar cell unit in a high temperature and humid environment. Photovoltaic module effect is one of the important factors affecting the power ...
