Key conclusion The tunnel oxide layer prepared by PE method has an optimal film thickness, and the film quality of the tunnel layer is directly related to the concentration of O atoms excited by plasma The degree of internal expansion of n-poly Si has an optimal range for passivation and contact pr...

Solar Cell Size The core of photovoltaic solar panels is solar cells, divided into single-crystal solar cells and polycrystalline solar cells, due to the bottleneck of efficiency, the market share of polycrystalline solar cells is becoming less and less, and currently single-crystal solar cells are...

    Laser processing is an important technology to reduce costs and increase efficiency of solar cells. It has obvious advantages over traditional technologies in the fields of PERC laser ablation, SE laser doping, repair and metallization; among them, PERC laser grooving, SE laser Doping...

    Heterojunction solar cells have always been favored by solar cell manufacturers and photovoltaic enterprise users for their low production costs and ideal photoelectric conversion rates. However, in order to further improve the photoelectric conversion rate of solar cells, they can be...

    In the production of solar cells, the performance and photoelectric conversion rate of silicon wafer solar cells are closely related to the surface structure of the solar cells. Therefore, chemical etching and texturing of silicon wafers is an important process during the manufacturing...

  Generally speaking, in order to more directly improve the photoelectric conversion rate of solar cells and maximize their efficiency in practical applications, battery manufacturers need to use physical means to prepare textured light-trapping structures on the surface of solar cells.  T...

    Proper post-processing of thin-film solar cells is one of the important means to improve the performance of thin-film solar cells. As a common post-processing process, the annealing process can greatly improve the crystallinity of thin-film materials, remove defects, adjust phase compo...

Advantage: 1. The process flow is short. The HJT solar cell process mainly includes four links: texturing, amorphous silicon deposition, TCO deposition, and screen printing, which is much less than that of PERC (10) and TOPCON (12-13). Among them, the PECVD method is mainly used for amorphous silico...

    In order to fundamentally and directly improve the photoelectric conversion rate of TOPcon solar cells, cell manufacturers usually need to carry out an oxidative annealing process on the surface of the solar cell, so that the deposited thin film material has a higher square resistance/...

    The production of solar cell electrodes is an important part of the solar cell manufacturing process, which will directly affect the performance and stability of solar cells. In the process of its production, the selection of electrode materials for solar cells is particularly importan...

1.Texturing     The texturing section (a total of 6 lines) includes pre-cleaning - pure water washing before texturing - texturing *3 - pure water washing after texturing - post-cleaning - pure water washing after cleaning - pickling - pure water washing after pickling - slow lifting pre-d...
