n-type PERT and PERL structures both offer a high efficiency potential. In this work we applied ion implantation for the realization of both the emitter and the BSF of high-efficiency PERT and PERL structures and laser processes for local BSF formation showing efficiency benchmarks for those in principle industrially feasible technologies.
The main two configurations of this concept are Passivated Emitter Rear Totally Diffused (n-PERT) and Passivated Emitter Rear Locally Doped (n-PERL).

An overview of the Passivated Emitter and Rear Totally Diffused (PERT) solar cell is presented, which is a member of Passivated Emitter and Rear Contact (PERC) family. Due to its outstanding properties, n-type PERT is considered as a promising candidate in photovoltaics (PV).
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 .

TOPCon solar cells can be either n-type or p-type, with the n-type variation demonstrating higher efficiency and resistance to impurities. Building upon the foundation of PERC/PERT solar cells, understanding the structure of TOPCon is crucial. PERT solar cells, for instance, utilize an n-type crystalline silicon (c-Si) bulk layer coupled with a p+ emitter layer to form the p-n junction. The ...
