    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...

    The full English name of PID is: Potential Induced Degradation, that is, potential induced degradation.     In 2005, a company in the United States discovered and proposed the PID effect for the first time, which specifically refers to the long-term operation of the module at...

    The photovoltaic industry is facing a new round of technological reform, and many processes will be used in the production process of solar cells and modules.     One of the major optical losses in solar cells is surface light reflection. The surface light reflection loss of...

    Unlike many other solar cell production processes, the sintering process directly reduces the contact resistance and improves the contact stability of the cell surface through physical means.     The principle of the solar cell sintering process   The working principle a...
