Inverted GaInP/GaAs Three-Terminal Heterojunction Bipolar Transistor Solar Cell
Marius H. Zehender, Simon. A. Svatek, Myles A. Steiner +6
Here we present the experimental results of an inverted three-terminal heterojunction bipolar transistor solar cell (HBTSC) made of GaInP/GaAs. The inverted growth and processing e…
III-V-on-silicon triple-junction based on the heterojunction bipolar transistor solar cell concept
E. Antolin, M. H. Zehender, S. A. Svatek +2
We propose a new triple-junction solar cell structure composed of a III-V heterojunction bipolar transistor solar cell (HBTSC) stacked on top of, and series-connected to, a Si sola…
High open-circuit voltage in transition metal dichalcogenide solar cells
Simon A. Svatek, C. Bueno, Der-Yuh Lin +9
The conversion efficiency of ultra-thin solar cells based on layered materials has been limited by their open-circuit voltage, which is typically pinned to a value under 0.6 V. Her…
Potential of the three-terminal heterojunction bipolar transistor solar cell for space applications
Antonio Martí, Pablo García-Linares, Marius Zehender +8
Multi-terminal multi-junction solar cells (MJSC) offer higher efficiency potential than series connected (two-terminal) ones. In addition, for terrestrial applications, the efficie…
Considerations for the design of a heterojunction bipolar transistor solar cell
Elisa Antolin, Marius H. Zehender, Pablo Garcia-Linares +2
Independent current extraction in multi-junction solar cells has gained attention in recent years because it can deliver higher annual energy yield and can work for more semiconduc…
Triplet excitation and electroluminescence from a supramolecular monolayer embedded in a boron nitride tunnel barrier
Simon A. Svatek, James Kerfoot, Alex Summerfield +7
We show that ordered monolayers of organic molecules stabilized by hydrogen bonding on the surface of exfoliated few-layer hexagonal boron nitride (hBN) flakes may be incorporated…
Photodiodes based in La0.7Sr0.3MnO3/single layer MoS2 hybrid vertical heterostructures
Yue Niu, Riccardo Frisenda, Simon A. Svatek +9
The fabrication of artificial materials by stacking of individual two-dimensional (2D) materials is amongst one of the most promising research avenues in the field of 2D materials.…
Lithography-free electrical transport measurements on 2D materials by direct microprobing
Patricia Gant, Yue Niu, Simon A. Svatek +6
We present a method to carry out electrical and opto-electronic measurements on 2D materials using carbon fiber microprobes to directly make electrical contacts to the 2D materials…
Gate Tunable Photovoltaic Effect in MoS2 vertical P-N Homostructures
Simon A. Svatek, Elisa Antolin, Der-Yuh Lin +8
P-n junctions based on vertically stacked single or few layer transition metal dichalcogenides (TMDCs) have attracted substantial scientific interest. Due to the propensity of TMDC…
Highly responsive UV-photodetectors based on single electrospun TiO2 nanofibres
Aday J. Molina-Mendoza, Alicia Moya, Riccardo Frisenda +9
In this work we study the optoelectronic properties of individual TiO2 fibres produced through coupled sol-gel and electrospinning, by depositing them onto pre-patterned Ti/Au elec…
