We report the performance enhancement of GaAs-based triple-junction solar cells using novel indium nanoparticles upon the cell front-surface to achieve the top cell current matching. The external quantum efficiency (EQE) enhancements of > 5% in top cell at wavelengths from 350 nm to 450 nm are achieved as the cell with indium nanoparticles plasmonic structure. Besides increasing in short circuit...
In this study, a new type of hybrid solar cell based on a heterojunction between poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and vertically aligned n-type GaAs nanowire (NW) arrays is investigated. The GaAs NW arrays are fabricated by directly performing the nano-etching of GaAs wafer with spun-on SiO2 nanospheres as the etch mask through inductively coupled plasma reactive...
A new type of hybrid solar cells based on a heterojunction between PEDOT:PSS and vertically-aligned n-type GaAs nanowire arrays is investigated. Such solar cells exhibit a power conversion efficiency of 3.46 %.
Large-area GaAs nanowires are fabricated by using SiO2 nanoparticles as a mask. SiO2 nanoparticle monolayer is spin-coated on the GaAs substrate and GaAs nanowires are etched by induced-coupled plasma reactive ion etcher.
As a result of the ability to tune the band-gap of III-V compound semiconductor materials to match the solar spectrum, solar cells made from II -V materials such as GaAs and InGaP have unsurpassed conversion efficiencies. However, after the deposition of the solar cell film, the substrate is of no further use for its performance. The reduction of the costs of III-V semiconductor materials and the...
Hybrid thin-film solar cells are fabricated on the glass substrate using ZnO nanorods, well-aligned single-crystalline Si nanowires (SiNWs), and poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) as well as micro-structured III-V semiconductors . The effect of introducing a solution-processed fullerene as an electron transport layer on the polymer/ZnO nanorod array composite...
