Technical Field
The utility model belongs to the photovoltaic power generation field, specifically speaking relates to a novel structure of photovoltaic module battery piece.
background
More than one billion people live in areas without or without electricity all over the world, and the electricity demand of people is increasingly urgent. With the rise of environmental protection consciousness all over the world and the increasingly serious natural disasters caused by global warming, people gradually decrease the attention of traditional energy sources and research and use the pollution-free and renewable energy sources such as solar energy, wind energy and the like. The solar cell market will continue to grow rapidly.
However, the existing photovoltaic module cell has certain defects, such as:
1. The front and back electrodes of the conventional photovoltaic module cell are positioned at the same position, and the hidden cracking of the module easily causes the reduction of the power generation efficiency;
2. The existing photovoltaic module cell piece completely adopts a layered structure, so that the bending resistance and the shearing resistance are poor;
3. The positive electrode of the cell of the existing photovoltaic module is positioned in the middle of the cell, so that the absorption of light is influenced.
Therefore, there is a need for a novel photovoltaic module cell structure that can solve the above problems.

Detailed Description
The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted so as to not unnecessarily limit the invention.
as shown in fig. 1 and fig. 2, the utility model provides a novel structure of photovoltaic module includes: a stack structure, a U-shaped back field 50, a positive electrode 60 and a back electrode 70.
Laminated structure includes from top to bottom in proper order: textured surface 10, N-type conductor 20, P-type conductor 30, and passivation layer 40.
The textured surface 10 is a textured surface formed on the surface of the silicon wafer and is used for increasing light absorption and reducing reflection. The junction surface of the N-type conductor 20 and the P-type conductor 30 forms a P-N junction for generating a photovoltaic effect. The passivation layer 40 can enable the cell to cross the potential gradient of the P-N junction, electrons can flow more stably, and further electron recombination is reduced, so that the photoelectric conversion phase rate of the cell is in a higher level.
the U-shaped back field 50 surrounds the stack by the lower half, which may support the stack. The positive electrode 60 is disposed on the top of the open side of the U-shaped back field 50. The back electrode 70 is disposed at a lower portion of the U-shaped back field 50.
The positive electrode 60 and the back electrode 70 are arranged in a staggered manner. Such a staggered arrangement may significantly reduce the risk of reduced power generation efficiency due to component subfissure.
The utility model discloses it is high to the hidden risk of splitting of current photovoltaic module battery piece, and bending resistance and anti-shear capacity are poor, and the poor defect of light absorption effect utilizes U type mosaic structure to stagger the relative position of positive electrode and back electrode, improved the light absorption effect and the anti-bending anti-shear capacity of battery piece, and reduced the hidden risk of splitting of battery piece.
