N-Type Module

2.0 VERSION OF  N-TOPCON CELL TECHNOLOGIES 2.0 VERSION OF  N-TOPCON CELL TECHNOLOGIES

The TOPCon cell applies cutting-edge and high-efficiency passivation contact technology, and uses a micro-nano tunneling oxide layer and a carrier-selective microcrystalline silicon film laminated functional structure on the back. This innovative structure demonstrates a two-way improvement in passivation performance and electrical conductivity, which brings significant improvements in cell conversion efficiency and power generation performance. The highest efficiency of N-type HOT2.0 cell is close to 25% in mass production, showing broad application prospects.

In short, TOPCon and HIT achieve efficiency improvements through passivation to reduce the number of sub-surface recombination rates. The former uses tunneling oxide layers and HIT

uses intrinsic amorphous silicon film. The differences in the methods lead to the respective manufacturing processes, resulting in the difference in the commercial cost between the two.

BETTER TEMPERATURE COEFFICIENT BETTER TEMPERATURE COEFFICIENT

The temperature coefficient of a similar P-type module is -0.35%/℃ while that of N-type is modified to -0.30%/℃. This means the power generation performance is particularly outstanding at high temperature. Omnis Solar Power's N type module power will increase with the bettertemperature coefficient (0.75% higher compared with PERC).

Under the same external environment, N Type's operating temperature is lower ( >1 % compared with the same specification P type ) and the heat loss is greatly reduced.

Under high temperature condition, the advantage will further expand (~2% higher than P-type).

HIGHER BIFACIALITY WITH MORE POWER GAINS HIGHER BIFACIALITY WITH MORE POWER GAINS

The bifacial factor or traditional PERC module is 70% while that of TOPCon module is modified up to 85%. The corresponding power gain is around 2.03%. According to the formula, the power gain of traditional PERC module due to the rear side power gain is 9.45% while that of a TOPCon module is 2 % more due to the 15% bifacial factor increase (under STC condition and average ground reflectivity). Cortex N-type power output will increase with the bettertemperature coefficient (0.75% higher compared with PERC). Under the same external environment, Tiger Neo’s operating temperature is lower ( >1 % compared with the same specification P type ) and the heat loss is greatly reduced. Under high temperature condition, the advantage will further expand (~2% higher than P-type). The power warranty can achieve 30 years compared to a traditional P-type module. The first year degradation is lower than 1% which means the power output at year 30 is guaranteed to be at least 87.4%. Power gain contrast due to the increase of bifacial factor.
