TOPCon: the next mainstream PV cell technology after p-mono PERC by 2025

Understand how TOPCon has evolved into the leading candidate to replace p-mono PERC as the mainstream solar cell technology in production.
Which companies are at the forefront of TOPCon expansions to the 10-20 GW level today?
How much efficiency gain is provided by TOPCon today, compared to state-of-the-art p-mono PERC in volume production? And how much headroom is left for further TOPCon efficiency gains?
Is TOPCon specific to cell producers in China; how are module assembly companies globally addressing module supply to the market using third-party TOPCon cells bought in?
