Although the power conversion efficiencies (PCEs) of bulk heterojunction (BHJ) organic solar cells (OSCs) continue increasing toward 20% milestone, important factors for industrial application are mostly neglected, such as photostability and cost potential. Single-component OSCs (SCOSCs) employing materials with chemically bonded donor acceptor moieties successfully overcome immiscibility betwe...
In this paper, we present a spectral analysis of Surface Plasmon Resonance (SPR) sensor based on multilayer graphene (MLG) operating as terahertz refractometer. This device's structure is Kretschmann configuration, and the layers are modeled surface impedances with conductivity described by Kubo model. The structure's electromagnetic response obtained from Generalized Coefficients Model, consid...
We propose and numerically investigate a perfect ultra-narrowband absorber with an absorption bandwidth of only 1.82 nm and an absorption efficiency exceeding 95% in the visible region. We demonstrate that the perfect ultra-narrowband absorption is ascribed to the coupling effect induced by localized surface plasmon resonance. The influence of structural dimensions on the optical performance is...
(Bi2Te3)0.25(Sb2Te3)0.75 solid solution is a p type thermoelectric compound with optimum efficiency among the (Bi2Te3)x (Sb2Te3)1-x compounds with variable x. Increment of Bi2Te3 segment in the Bi-Sb-Te system decrease in hole concentration, which result in carriers transport tuning, an increment of Seebeck coefficient and decrement of electrical and thermal conductivities. An excess of Telluri...
Spoof localized surface plasmons (LSPs) have proven significant advantages in sensing and detection. In this work, we propose a high- Q -factor high-sensitivity hybridized spoof LSP sensor mixed-resolution algorithm. The consists of two concentric inner outer structures with corrugated rings coupled to each other. achieved is up 178, the figure merit ( FoM ) 30. Moreover, algorithm, combined mu...
