A hydrogen atom passivation method and a hydrogen atom passivation device

Abstract

The invention discloses a hydrogen atom passivation method. The hydrogen atom passivation method comprises the steps of placing a material to be passivated in a cavity, and then filtering a first mixed body containing hydrogen atoms by a preset filtering plate, wherein the hydrogen atom concentration in a second mixed body obtained by filtering is needed to be higher than the hydrogen atom concentration in the first mixed body grown in advance; and passivating the material to be passivated by the second mixed body. The hydrogen atoms can be effectively combined with composite centers such as dangling bonds and structure defects in the material to be passivated, so that the numbers of the dangling bonds of the material to be passivated are reduced, and the passivation effect of the materialto be passivated is improved; and meanwhile, the first mixed body is filtered to form the second mixed body by the filtering plate, the moving speed during diffusion of the second mixed body can be effectively reduced, so that the bombardment effect of the second mixed body on a surface of the material to be passivated is effectively reduced, and the passivation effect of the material to be passivated is improved. The invention also provides a hydrogen atom passivation device having the same beneficial effect.

Description

technical field [0001] The invention relates to the field of solar energy manufacturing, in particular to a hydrogen atom passivation method and a hydrogen atom passivation device. Background technique [0002] With the continuous advancement and development of science and technology in recent years, the development and application of clean energy has become more and more important. As a typical clean energy, solar energy has played a key role in promoting the improvement of the global energy structure. Among them, photovoltaic power generation, as the most effective way to utilize solar energy resources, has attracted more and more attention. [0003] At this stage, the efficiency of solar cells mainly depends on two aspects, one is optical loss, and the other is electrical loss. Among them, the electrical loss is mainly affected by the recombination center in the body or surface of the solar cell. The majority and minority carriers in the solar cell will recombine at the ...
