The Development of TOPCon

• PERC (Passivated Emitter Rear Contact) was one step to overcome therecombination problem of metal – semiconductor contacts (widelyused in the industry, mainly on mono cells)

• TOPCon is the next step to get closer to a perfect solar cell– Carrier selective contacts (optimized for electrones and holes)– Higher Fill Factor– Higher open circuit voltage– Most efficient on N-type wafers

• Target is to keep costs and process complexity low to make iteconomically successful

• Trina is ready to produce TOPCon Cells with 23% efficiency in volume

TOPCon = Tunnel Oxide Passivated Contact

• Trina N-type i-TOPCon cells combine the advantage of PERC (relative low cost) and TOPCon (high efficiency)

• Best laboratory i-TOPCon bifacial cell with 24,1% efficiency• First demonstration of mass produced i-TOPCon cells with

median efficiency of >23%• +20W over current PERC technology on a 72/144 cell module
