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
Photovoltaics; solar cells; silicon; heterojunctions; high efficiency Silicon heterojunction solar cells consist of thin amorphous silicon layers deposited on crystalline silicon wafers. This design enables energy conversion efficiencies above 20% at the industrial production level.
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.
Si/organic heterojunction solar cells 4.2.1. Development status In 1990, Lewis and coworkers firstly presented a Si/organic heterojunction solar cell with a very low PCE of ∼1% . The heterojunction is made of poly- (CH 3) 3 Si-cyclooctatetraene and Si.
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.
