Advantages of Radiance TOPCon Modules
The recombination of electrons and holes on the surface and any interface is the main factor limiting cell efficiency, and
various passivation technologies have been developed to reduce the recombination, from early-stage BSF (Back Surface Field) to currently popular PERC (Passivated Emitter and Rear Cell), latest HJT (Heterojunction) and nowadays TOPCon technologies. TOPCon is an advanced passivation technology, which is compatible with both P-type and N-type silicon wafers and can greatly enhance cell efficiency by growing an ultra-thin oxide layer and a doped polysilicon layer on the back of the cell to create a good interfacial passivation. When combined with N-type silicon wafers, upper efficiency limit of TOPCon cells is estimated to be 28.7%, outclassing that of PERC, which would be about 24.5%. TOPCon's processing is more compatible to the existing PERC production lines, thus balancing better manufacturing cost and higher module efficiency. TOPCon is expected to be mainstream cell technology in the coming years.
More Energy Yield
TOPCon modules enjoy better low-light performance. Improved low light performance is mainly related to the optimization of series resistance, leading to low saturation currents in TOPCon modules. Under low-light condition (200W/m²), performance of 210 TOPCon modules would be about 0.2% higher than 210 PERC modules.
Better Power Output
Modules’ operating temperature impacts their power output. Radiance TOPCon modules are based on N-type silicon wafers with high minority carrier lifetime and higher open-circuit voltage. The higher open-circuit voltage, the better module temperature coefficient. As a result, TOPCon modules would perform better than PERC modules when operating in high temperature environments.
