Product White Paper . Product White Paper of Tiger Neo N-type TOPCon Module 1. Background The technology market trends of Tiger Neo TOPCon N-type module Most are familiar with traditional P-type cell technology. With large-scale manufacturing of monocrystalline silicon wafers, P-type mono PERC cell technology has been deployed on a large majority of projects since 2017. Mainstream module manufactur- ers have used mono PERC due to a simple manufacturing process, low cost, and cell conversion e ciency improvements. However, the e ciency of PERC cells has approached a limit of , and cost reduction has also slowed. Meanwhile, new cell technology is developing rapidly, and N-type cells are most likely to replace P-type cells to become the next-generation mainstream technology.
TOPCon cell technology is a new passivated contact solar cell developed by the Fraunhofer Solar Energy Institute in Germany. Passivation is a key technology in determining maximum efficien- cy of the cell, as shown in the picture below. 380 405 470 540 620 19.3% 20.1% 20.9% 21.3% 22.2% 23.0% 16.0% 17.0% 18.0% 19.0% 20.0% 21.0% 22.0% 350 4 0 450 ...
