Surface passivation for silicon solar cells using stable extrinsic field effect passivation

Thesis

One of the largest challenges for high efficiency solar panels is the recombination of photo-generated carriers at the silicon surface. This recombination can be reduced by both chemical passivation and Field Effect Passivation (FEP). Conventionally, this is achieved by the SiNx antireflection coating. However, this is sub-optimal and insufficient for high efficiency devices. This thesis focuses on introducing FEP, independent of the antireflection coating, to allow superior surface passiv...
