preparation example Construction

[0020] The present invention also proposes a method for preparing a photovoltaic module with a groove structure, which includes the following steps:

[0021] (1) Prepare the metal backplane, and form a plurality of array-distributed grooves on the metal substrate by using a selective etching process;

[0022] (2) The insulating layer is then formed on the surface of the metal backplane and the side and bottom surfaces of the groove, and then a conductive circuit layer is formed on the insulating layer;

[0023] (3) Place the back-contact solar cell in the groove, and make electrical connection with the conductive circuit layer;

[0024] (4) Inject encapsulation glue and cover with a glass cover to form a photovoltaic module with a groove structure.

Abstract

The invention provides a photovoltaic module having a groove structure and a preparation method thereof. The photovoltaic module consists sequentially from bottom to top of a metal backboard, an insulating layer, a conducting circuit layer, a plurality of back contact solar cells, a packaging adhesive and a glass cover plate. The metal backboard includes a plurality of grooves in array distribution. The insulating layer covers the upper surface of the metal backboard and the sides and bottoms of the grooves. The conducting circuit layer is located on the insulating layer and electrically connected with the plurality of back contact solar cells. Each groove accommodates one or more back contact solar cells. According to the invention, the back contact solar cells are arranged in the grooves in the metal backboard so that the back contact solar cells can transfer the heat generated in the photoelectric conversion to the outside directly through the metal backboard, the heat dissipating performance of the solar cell module is improved, and the service life of the solar cell module is further prolonged.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a photovoltaic module with a groove structure and a preparation method thereof. Background technique [0002] At present, traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more prominent. At the same time, there are still 2 billion people in the world who do not have normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of people's attention because of its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human beings. The energy of solar energy reaching the ground every second is as high as 800,000 kilowatts....
