Abstract

The invention provides a back-contact solar cell assembly which comprises an overlaid transparent layer (10), a first packing layer (20), a battery piece layer (30), a second packing layer (40) and a back plate layer (60). A first conductor and a second conductor are arranged between the back plate layer (60) and the second packing layer (40). The back-contact solar cell assembly further comprises a first hole channel and a second hole channel which are both formed in the battery piece layer (30) and the second packing layer (40). The first hole channel is communicated with a positive electrode of a battery piece of the battery piece layer (30) and the first conductor, the second hole channel is communicated with a negative electrode of the battery piece of the battery piece layer (30), the first hole channel and the second hole channel are filled with conductive slurry (50), and the back plate layer (6) is made of glass. The technical scheme of the back-contact solar cell assembly effectively solves the problems that a back-contact solar cell assembly in the prior art is complex in manufacturing process and high in rejection rate.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a back-contact solar battery module. Background technique [0002] With the depletion of non-renewable resources such as oil and gas, human beings pay more and more attention to the development and application of renewable energy. As a device that converts solar light into electrical energy through the photovoltaic effect, solar cells are environmentally friendly and inexhaustible. [0003] At present, the development and application of solar energy technology are changing with each passing day. Solar cells can generally be divided into crystalline silicon solar cells, thin film solar cells, dye-sensitized solar cells and organic solar cells. After years of technological progress and relatively mature market promotion, crystalline silicon solar cells are gradually occupying a dominant position in the field of solar energy. [0004] In order to improve the photoelectric co...
