Heterojunctions can increase the efficiency of solar cell devices relative to homojunctions, but there is a large parameter space with significant tradeoffs that must be considered.
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 performance of the inverted architecture-based PHJ100 is comparable with the standard-architecture CsPbI 3 solar cells, thus demonstrating the enormous potential of the phase heterojunction solar cell concept.
However, in CdTe (ref. 11), CIGS (ref. 12) and GaAs (ref. 13) solar cells, a p–n junction can also be formed as a heterojunction (Fig. 1c). Finally, another noteworthy example is the use of junctions of varying dimensionality, such as a 3D/2D junction (Fig. 1d) in perovskite solar cells 14, leading to improvements in their efficiency and stability.
This methodology enables the parametric quantification of microscopic characteristics for silicon-based heterojunctions with greater convenience and accuracy. Solar cells with functional structures of silicon-based heterojunctions, including silicon heterojunctions (SHJs) or dopant-free heterojunctions (DFHJs), are multilayer thin-film 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)).
