Van der Waals metal-semiconductor junction: Weak Fermi level pinning enables effective tuning of Schottky barrier.
TL;DR: 2D metals are used, which are bounded with 2D semiconductors through van der Waals interactions, and the Schottky barrier at the metal-semiconductor junction becomes tunable and can vanish with proper 2D metals.
Journal ArticleDOI
Nanostructured black silicon and the optical reflectance of graded-density surfaces
TL;DR: In this article, the authors fabricate and measure graded-index "black silicon" surfaces and find the underlying scaling law governing reflectance, which shows that as the density-grade depth increases, reflectance decreases exponentially with a characteristic grade depth of about 1/8 the vacuum wavelength or half the wavelength in Si.
Journal ArticleDOI
Efficient black silicon solar cell with a density-graded nanoporous surface: Optical properties, performance limitations, and design rules
TL;DR: In this article, the authors study optical effects and factors limiting performance of 16.8% efficiency black silicon solar cells, and propose universal design rules for high-efficiency solar cells based on density-graded surfaces.
Journal ArticleDOI
Polycrystalline silicon passivated tunneling contacts for high efficiency silicon solar cells
Bill Nemeth,David L. Young,Matthew Page,Vincenzo LaSalvia,Steve Johnston,Robert C. Reedy,Paul Stradins +6 more
TL;DR: In this article, the authors apply n-and p-type polycrystalline silicon (poly-Si) films on tunneling SiOx to form passivated contacts to n-type Si wafers.
Journal ArticleDOI
Realization of GaInP/Si Dual-Junction Solar Cells With 29.8% 1-Sun Efficiency

TL;DR: In this article, Si-based tandem solar cells with 1.8-eV rear-heterojunction GaInP top cells were constructed separately and joined by mechanical stacking using electrically insulating optically transparent interlayers.
