Amorphous silicon annealing solar cell panel

Abstract

The invention discloses an amorphous silicon annealing solar cell panel. The amorphous silicon annealing solar cell panel comprises a substrate, wherein solar cell panels are installed on the substrate, and the solar cell panels are arranged on the substrate in a matrix mode, and are connected through connecting wires to form a circuit; the solar cell panels are made of an amorphous silicon film,wherein the amorphous silicon film is prepared by PECVD or APCVD deposition and has the thickness of 1-50mu; an annealing furnace is filled with N2, and high-temperature annealing is performed for 10hat 600 DEG C; a layer of polycrystalline silicon thin film is grown on the upper surface of a silicon wafer so as to complete the thermal annealing; sliding plates are fixedly connected to a pair ofvertical side walls of the substrate; a baffle is fixedly connected to one vertical side walls of the sliding plates; one side of the baffle is fixedly connected with the same ends of the two slidingplates; and sliding grooves are symmetrically formed in the opposite side walls of the two sliding plates. The amorphous silicon annealing solar cell panel is suitable for a conventional silk-screen printing all-aluminum back field battery and a back passivation point contact battery, and the service life of the solar cell panel is prolonged; and in addition, that dust and dirt on the solar cell panel can be effectively erased.

Description

technical field [0001] The invention relates to the technical field of solar cell equipment, in particular to an amorphous silicon annealed solar cell panel. Background technique [0002] Solar energy is renewable and clean energy. With the development of photovoltaic power generation technology, solar cell products are widely used in various types of products and building structures. In large-scale solar products and building structures, the solar cell area usually needs to be laid on a large area to meet the power consumption requirements. At the same time, in the solar building structure, the solar cell area is gradually departing from the conventional rectangular design, and is more inclined to design circular, fan-shaped, S-shaped and other special-shaped structures with arc boundaries to enhance the design aesthetics. All of these require splicing and laying a large number of solar cells, and at the same time require small seams and high matching between adjacent cel...
