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
Amorphous/crystalline silicon heterojunction (SHJ) solar cells hold the world-record power conversion efficiency (PCE; 26.7%) among c -Si solar cells, when integrated with an all back-contact design. Here, we present a roadmap to gaining high-efficiency SHJ solar cells, whose PCE is pushed to 23.4% on 6-in devices.
The prominent examples are low-thermal budget silicon heterojunction (SHJ) solar cells and high-thermal budget tunnel-oxide passivating contacts (TOPCon) or doped polysilicon (poly-Si) on oxide junction (POLO) solar cells (see Fig. 1 (e)– (g)).
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 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.
