Abstract Semiconducting barium disilicide (BaSi 2), which is composed of earth-abundant
elements, has attractive features for thin-film solar cell applications. Both a large absorption …

We investigated the effect of a 3-nm-thick amorphous Si (a-Si) capping layer on the hole
transport properties of BaSi 2 films. The contact resistance decreased with decreasing …

Semiconducting BaSi 2 has attractive features for thin-film solar cell applications because
both a large absorption coefficient and a long minority-carrier diffusion length can be …

Undoped 0.5-μm-thick BaSi 2 epitaxial films were grown on Si (111) substrates with various
ratios of the Ba deposition rate to the Si deposition rate (R Ba/R Si) ranging from 1.0 to 5.1 …

p-BaSi 2/n-Si heterojunction solar cells consisting of a 20 nm thick B-doped p-BaSi 2
epitaxial layer (p= 2.2× 10 18 cm− 3) on n-Si (111)(ρ= 1–4 Ω cm) were formed by molecular …

We performed advanced opto-electrical simulations on thin-film BaSi 2 solar cells. First,
absorption spectra of BaSi 2-pn homojunction solar cells on Si substrate were calculated …

The effect of low growth rate deposition (LGD) of BaSi 2 on the film quality and performance
of silicon heterojunction solar cells was investigated. The total thickness of the BaSi 2 layer …

Abstract n-Mg 2 Si/p-Si heterojunction solar cell with a 1.4 µm thick unintentionally doped
(n= 3× 10 17 cm− 3) silicide epitaxial layer on p-Si (1 1 1)(p= 5× 10 14 cm− 3) was grown by …

BaSi2 is a promising absorber material for next-generation thin-film solar cells (TFSCs). For
high-efficiency TFSCs, a suitable interlayer should be found for every light absorber …

A double heterojunction solar cell consisting of a solar absorber and electron/hole transport
layers (ETL/HTL) is ideally efficient and can contribute to the exploitation of solar energy …
