Abstract

The invention relates to a photovoltaic module comprising a light-transmitting layer, a battery assembly and an encapsulating layer that are successively stacked. The battery assembly comprises at least one battery piece laid between the light-transmitting layer and the encapsulating layer and having a side facing the light-transmitting layer, wherein the side and the light-transmitting layer arearranged at a predetermined interval. The predetermined interval causes the side, facing the light-transmitting layer, of the battery piece not to be in direct or indirect contact with the light-transmitting layer such that a problem is avoided that the battery piece is pressed to fracture or smash during a stacking process. In addition, removal of an encapsulating material between the battery piece and the light-transmitting layer is beneficial to reducing the production cost and the light-absorbing rate of the encapsulating material, and avoids a transmittance decrease and am efficiency decrease of the photovoltaic module due to the deterioration of the encapsulating material. The photovoltaic module is easy to produce, high in preparation efficiency and finished product rate, and low inproduction cost.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic module and a preparation method thereof. Background technique [0002] Photovoltaic power generation is being used more and more widely as a clean power generation method. Such as Figure 5 As shown, the existing crystalline silicon photovoltaic module adopts encapsulation adhesive film to encapsulate the cells (groups). From the front to the back of the photovoltaic module, "transparent flat cover plate 6 + upper encapsulation film 7 + several cells 3 (the whole assembly The number of cells required) + the lower encapsulation film 8 + the flat backplane 5" are laid up in sequence. The front and back of the cell are completely covered by the encapsulation film, and then the adhesive film undergoes a cross-linking reaction through the lamination process, so that the cell, the cover plate and the back plate are bonded as a whole. When working,...
