Heterojunction technology is currently a hot topic actively discussed in the silicon PV community. Hevel recently became one of the first companies to adopt its old micromorph module line for manufacturing high-efficiency silicon heterojunction (SHJ) solar cells and modules.
Amongst the potential dopants, tungsten, zirconium and cerium were reported to enable highly efficient devices [, , ]. The interplay between the electrode and the rest of the device is stringent in Si heterojunction solar cells, and this calls for a holistic approach to fully harvest the potential of this technology.
Silicon heterojunction devices rely on the use of thin-film silicon coatings on either side of the wafer to provide surface passivation and charge carrier-selectivity. Beyond traditional indium tin oxide, multiple higher-mobility indium-based transparent conductive oxides have been employed successfully in HJT cells.
3.1. Si heterojunction solar cell based on doped amorphous Si films 3.1.1. Development history: from 13% to 26.7% Si heterojunction (SHJ) solar cells consist of the happy marriage of c-Si as an absorber layer, with thin-film Si for the selective-contacts of both polarities.
Silicon heterojunction (SHJ) solar cells have achieved a record efficiency of 26.81% in a front/back-contacted (FBC) configuration. Moreover, thanks to their advantageous high VOC and good infrared response, SHJ solar cells can be further combined with wide bandgap perovskite cells forming tandem devices to enable efficiencies well above 33%.
The application of silicon heterojunction solar cells for ultra-high efficiency perovskite/c-Si and III-V/c-Si tandem devices is also reviewed. In the last, the perspective, challenge and potential solutions of silicon heterojunction solar cells, as well as the tandem solar cells are discussed. 1. Introduction
