What are the components of Pert cell?

The components of PERT cell are silicon substrate, emitter, front and rear passivation layers, antireflection coating, texturing, BSF, front and back contacts. Emitter is mostly formed through difusion [27, 31] and BSF is also realized through difusion. There are various techniques to perform difusion .
