    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...

What is a PN junction?   A PN junction is a semiconductor structure that is used as a basic component for the construction of various semiconductor devices. How did it come to be?   By using different doping processes to tightly bond P-type semiconductors and N-type semiconductors to form...

Luminescence imaging The basic principle of luminescence imaging is to excite the surface of a sample to make it glow, and then capture the luminescent imaging with a camera. Two imaging methods commonly used in crystalline silicon cells PL, Photo-luminescence, is excited by incident photons. The li...

TOPCon technical difficulties Difficulties in the TOPCon process Boron diffusion LPCVD winding plating problem PE-poly film burst problem Yield loss due to long process steps Burn-through and diffusion destroy passivation The high-temperature process causes damage to the silicon wafers TOPCon cost d...

  One of the major optical losses in solar cells is surface light reflection. The surface light reflection loss of polished silicon wafers is up to 34%, and the reflection must be reduced to ~10% or less in order to prepare high-efficiency solar cells. In crystalline solar cells, suede is often...

As a key material affecting the conductivity of solar cells, a series of factors such as height, width, and number of solar cell grid wires will determine the photoelectric conversion rate of solar cells. Therefore, after the solar cells are screen-printed and cleaned and texturized, solar cell manu...

1. Overview of the current situation of photovoltaic cell technology: efficiency improvement and cost reduction is an eternal topic for the development of the photovoltaic industry, and in many links of the industrial chain, the solar cell is the core of technological progress and determines the eff...

Silicon solar cells can generally be divided into monocrystalline, polycrystalline and amorphous silicon solar cells, of which monocrystalline silicon cells are currently the fastest developed solar cells, its structure and production process has been finalized, and is widely used in space and groun...

With the continuous improvement of the yield rate of the photovoltaic module market, the quality requirements of solar cells in photovoltaic modules are also increasing with the increase of their yield rate, but the passivation of the surface of solar panels is often deteriorated due to the PID effe...
