Higher e�ciency under low irradiation.Higher e�ciency in the- infrared wave length
PERFORMANCEDislocation density and Fe impurity a�ect minority carrier lifetime which is concerned with performance.
Low O impurity determines a good LID performance.
Multi silicon structure
Mono silicon structure
Mono-C-Si modules generate less heat than multi-c-Si module.
Therefore, the nominal operating cell temperature (NOCT) for a mono cell is lower than for a multi-cell, By operating at a lower temperature, mono cells and modules generate more energy.
Lower initial light induced degradation (LID), means higher reliability and more energy generated than standard mono or multi -crystalline modules
