    Copper electroplating technology is one of the important technical routes for heterojunction solar cells  to reduce costs and increase efficiency in recent years. Its advantage is that it has stronger conductivity than traditional silver paste and has low contact resistance. The u...

The next generation of photovoltaic mainstream technology Compared to those solar cell manufacturing that have more than 10 steps of processing, HJT cells only need 4 steps, all at low temperatures. The streamlined process effectively reduces production costs and carbon emissions and is more in...

Photovoltaic solar cells, often referred to as solar panels, are at the forefront of renewable energy technologies. Harnessing the energy from the sun, these devices have the potential to revolutionise our energy landscape and reduce our dependency on fossil fuels. There is a lot to unders...

Solar cells, called "solar chips" or "photocells", are devices that directly convert light energy into electricity through the photoelectric effect or photochemical effect. To evaluate the advantages and disadvantages of solar cells, the following technical parameters need to be considered: 1. Open...

   In the production process of crystalline silicon solar cells, the impact of the screen printing process on their surface characteristics and performance is usually very direct and critical. However, in order to understand the impact of screen printing on the surface characteristics and...

     The cost reduction direction of TOPCon is silicon wafer, silver paste, equipment cost, yield rate, etc. Silicon wafer:      N-type silicon wafers are made by doping phosphorus. Since phosphorus atoms have poor solubility with silicon, the purity and production proc...

    In the solar cell production process, cleaning and texturing is one of the important links. Optimization and technological upgrading of the texturing process can improve the conversion efficiency of solar cells and reduce production costs. The formation of texturing suede is affected...

What do "M" and "G" stand for in solar wafer size?   It begins with the letter "G", which means that the solar silicon wafer is full square Beginning with the letter "M", it means that the solar silicon wafer is Pseudo-square and has chamfer.   EG：     As an important link in t...

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...
