The LBSF battery is short for Local Back Surface Fields (BSF) cells and was developed by the Fraunhofer Institute in Germany. The efficiency of the 2 cm × 2 cm cell reaches 23.3%.
Features:
1. TCA growth oxide layer passivation battery front and back.
2. Frontal lithography made of pyramid (suede) structure.
3. Backside boron diffusion generally causes high surface recombination.
4. Partial aluminum diffusion creates surface contact with the battery.
