Designing a Concentrated High-Efficiency Thermionic Solar Cell Enabled by Graphene Collector
Xin Zhang, Xiaohang Chen, Jinchan Chen +2
We propose a concentrated thermionic emission solar cell design, which demonstrates a high solar-to-electricity energy conversion efficiency larger than 10\% under 600 sun, by harn…
Designing 24-hour Electrical Power Generator: Thermoradiative Device for Harvesting Energy from Sun and Outer Space
Xin Zhang, Guofeng Yang, Mengqi Yan +2
Energy harvesting from sun and outer space using thermoradiative devices (TRD), despite being promising renewable energy sources, are limited only to daytime and nighttime period,…
Designing Few-layer Graphene Schottky Contact Solar Cell: Theoretical Efficiency Limits and Parametric Optimization
Xin Zhang, Jicheng Wang, Yee Sin Ang +1
We theoretically study the efficiency limits and performance characteristics of few-layer graphene-semiconductor solar cells (FGSCs) based on a Schottky contact device structure. W…
Fractional Fresnel coefficients for optical absorption in femtosecond laser-induced rough metal surfaces
Muhammad Zubair, Yee Sin Ang, Kelvin J. A. Ooi +1
The surface morphology of metal influences its optical absorptivity. Recent experiments have demonstrated that the femtosecond laser induced surface structures on metals could be d…
Thickness dependence of space-charge-limited current in spatially disordered organic semiconductors
Muhammad Zubair, Yee Sin Ang, Lay Kee Ang
Charge transport properties in organic semiconductors are determined by two kinds of microscopic disorders, namely energetic disorder related to the distribution of localized state…
