The HJT cell initially investigated by Sanyo, Japan is a single-sided heterojunction structure, where the n-type diffused emitter is replaced by an n-type a-Si:H layer, and also a TCO layer is added compared to a single-crystal pn-junction solar cell.
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.
Sanyo (Japan) started introducing heterojunction solar cells with a-Si/c-Si structure of such structure in the 1980s. The manufactured devices consisted of n-type silicon wafers and emitters made of p-type conductivity amorphous silicon doped with boron. These solar cells had an efficiency of about 12%.
