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.
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%.
Nan Meng, ... Haixue Yan, in Progress in Materials Science, 2023 Heterojunction refers to a junction formed by two semiconductor materials with similar crystal structure, atomic spacing and coefficient of thermal expansion but different energy band gaps.
Zhengcao Li, in Journal of Materiomics, 2024 The most common and efficient method to form heterojunctions involves combining a semiconductor oxide photocatalyst with other semiconductors or carbon nanomaterial.
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)).
BaTiO 3 /metal heterojunctions were built via a simple piezodeposition method, which involves mixing BaTiO 3 nanoparticles (diameter: 200 nm) with three types of metal chloride (K2 PtCl 4, HAuCl 4 or Na 2 PdCl 4) followed by the ultrasound treatment to trigger the reduction reaction.
