TOPCon Solar Cell Concept The concept of the TOPCon cell was proposed by the Fraunhofer Institute for Solar Energy Systems (Fraunhofer-ISE) in Germany in 2013. The following figure shows the structural schematic diagram of the N-type passivation contact solar cell. The front side of TOPCon is not fundamentally different from conventional N-type solar cells or N-PERT

Preface: the past and present of photovoltaic cells – the end of the P-type era, the beginning of the N-type era The photovoltaic cell industry belongs to the midstream of the photovoltaic industry chain and is made of silicon wafers through cleaning, texturing, and other steps. Photovoltaic panels generate voltage and current under light, enabling
