Highly Transparent and Surface-Plasmon-Enhanced Visible-Photodetector Based on Zinc Oxide Thin-Film Transistors with Heterojunction Structure

Abstract: Highly transparent zinc oxide (ZnO)-based thin-film transistors (TFTs) with gold nanoparticles (AuNPs) capable of detecting visible light were fabricated through spray pyrolysis on a fluorine-doped tin oxide substrate. The spray-deposited channel layer of ZnO had a thickness of approximately 15 nm, and the thickness exhibited a linear increase with an increasing number of sprays. Furthermore, the ZnO thin-film exhibited a markedly smoother channel layer with a significantly lower surface roughness of 1.84 nm w… Show more

“…On this aspect, to enable large-scale manufacturing of PV-IEAs with embedded sensors, we expect that future research will focus on seamless integration of sensors onboard of PV modules, e.g. (i) through integration within the module laminate of thin-film transistors (TFTs) to be used as thermal sensors 75,76 and thin-film photodetectors (TFPs) to be used as optical sensors; 77 or (ii) integration within the module laminate of glass fibers (or other waveguides) with distributed Bragg reflectors, e.g. Fiber Bragg Grating (FBG) arrays, to be used as temperature and strain sensors; 78,79 or (iii) sensors can be integrated directly on the solar cell, e.g.…”

“…Over the past decade, the mobility (µ) of TFTs employing these semiconductors, such as InGaZnO, has greatly increased, and is comparable to that of polysilicon-based devices [7]. These metal oxide semiconductors also possess promise for various optoelectronic applications, including photodetectors and solar cells [8][9][10][11]. Inspired by the achievement of metal oxide films, another category of these materials, called InSnZnO (ITZO), was studied by our group in 2012 [12].…”
