Simplified processing of interdigitated-back-contacted silicon heterojunction solar cells

Silicon heterojunction (SHJ) solar cells are one of the most promising PV technologies nowadays due to high photoconversion efficiencies and low manufacturing costs. However, standard front/back-contacted (FBC) solar cells feature a front metal grid that brings shading to the front side of the devices, which limits the conversion efficiency of...

Fabrication of high temperature carrier-selective passivating contact solar cells for application in monolithic perovskite/c-Si tandem devices

Crystalline silicon (c-Si) homojunction architectures like aluminum back-surface field (Al-BSF) and passivated emitter and rear cell (PERC) dominated the solar cell market for the last decades. Recently, carrier-selective passivating contact (CSPC) designs have shown that they can effectively reduce recombination losses and exhibit efficiencies...

Ultra-thin thermal SiOx enabled poly-Si carrier selective passivating contacts for IBC solar cell application

Crystalline silicon solar cells based on poly-Si Tunnelling Oxide Passivating Contacts (TOPCon) is becoming one of the most promising solar cell structures that enable both high efficiency and low cost. The record efficiency for the Front-Back contacted (FBC) cell with TOPCon structure is 25.7 %. By moving both the metal contacts to the back...
