In the past three to five years, the photovoltaic industry's solar cell technology has been rapidly upgraded and iterated, and high-efficiency PERC solar cells have gradually replaced traditional all-aluminum back-field solar cells and become a new generation of "conventional" solar cells. So, after...

  What is photovoltaic silver paste?   The main principle of photovoltaic power generation is the photovoltaic effect of semiconductors, that is, when the silicon wafer is illuminated, the charge distribution state in the body changes to generate electromotive force, converting photons int...

   In the manufacturing process of solar cells, in order to prepare solar cell contact electrodes, it is necessary to print metal paste on silicon wafers using screen printing technology. After the sintering process, front and back electrodes are formed on the surface of the solar cell thr...

  Laser-enhanced contact optimization (LECO), or laser-enhanced contact optimization, patented by Cell Engineering GmbH in 2016, replacing the conveyor furnace (FFO) technology typically used for TOPCon solar cell.   In principle, the current formed by the laser is transmitted along the p...

After purposeful doping, the semiconductor bulk silicon introduces trace impurities to become an extrinsic semiconductor, which is divided into N-type and P-type two categories. 1. N-type crystalline silicon When the crystal silicon is mixed with trace impurities Group V elements, its five valence e...

     The manufacture of crystalline silicon modules involves fabricating silicon wafers, transforming the wafers into cells, and assembling cells into modules.     A wafer is a thin, flat disk or rectangle of base semiconductor material. Wafers are 180μm to 350μm th...

   As an upgraded version of passivated emitter and back-side cell (PERC) solar cells, the performance of tunnel oxide passivation contact (TOPCon) solar cells is very dependent on the silicon oxide layer and polysilicon layer. We found that different crystallization rates in polysilicon o...

  With the rapid development of renewable energy, solar photovoltaic technology has become an important clean energy source. Among photovoltaic modules, perovskite tandem cells are an emerging technology for future cost reduction and efficiency increase, which has attracted much attention. &nbs...

1.Development trend of surface passivation The top priority of crystalline silicon solar cells has always been their surface passivation. Early screen printing solar cells, limited by the technical means at the time, people simply introduced the TiO2 layer. However, the passivation function of TiO2...

                           Photovoltaic cell technology analysis of HJT ( heterojunction solar cell)       HJT (HeterojunctionwithIntrinsic Thin-film) - intrinsic thin film heterojunction solar cell. It has a s...

  What is a BC Solar Cell?    The base type of BC solar cell  is IBC solar cell (Interdigitated Back Contact) which is a pure single-sided solar cells.    Unlike TOPCON and HJT, which adopt a new passivation contact structure to improve the passivation effect and thus i...

  Component definition 1, with packaging and internal connection 2, can provide direct current output alone 3, with the smallest indivisible photovoltaic cell combination device     Component classification 1, according to the type of solar cell classification Crystalline silicon (sin...
