   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...

How to convert solar cell area/efficiency?   Monocrystalline silicon wafer area   The shape of the single crystal solar cell is generated by cutting a cylindrical silicon rod formed using the cinetol method. The calculation idea of the area of the monocrystalline silicon wafer is derived f...
