The most important features of microcrystalline silicon (Fc-Si:H) and microcrystalline silicon based p-i-n solar cells (specially those deposited by VHF-Glow Discharge) are reviewed. Since such material has been recognized to be a photovoltaically active material, stabilized cell efficiencies have steadily risen and have now reached 12% in the so called “micromorph” (microcrystalline/amorphous)...

dna typing is a new method with important applications in forensic medicine. in the present study, we evaluated application of dna typing in iran. loci hum lpl, hum tpox, hum f13, hum vw 31a, hum th01 and hum fes/fps of dna short tandem repeats were studied. to determine sensitivity of the test, 85 mother-child couples (1020 chromosomes) that were referred to dna section of legal medicine organ...

Solar cells transparent in the visible range are highly requested for integration see-through photovoltaic (PV) applications such as building glass façades or greenhouse roofs. The development of advanced PV can fully exploit tandem technology where top cell absorbs near-ultraviolet solar spectrum while bottom one near-infrared part. Herein, a possible implementation this paradigm, namely, stru...

We report direct numerical simulations of a pair wings in horizontal tandem configuration, to analyze the effect their aspect ratio on flow and aerodynamic performance system. The are immersed uniform free-stream at Reynolds number Re = 1000, they undergo heaving pitching oscillation with Strouhal St 0.7. ratios forewing hindwing vary between 2 4. system is dictated by interaction trailing edge...

Abstract In this work, the interaction of separated wake front wing with rear a tandem configuration is investigated for high-speed stall conditions by means hybrid RANS/LES simulations, using zonal AZDES method. After characterization transonic buffet on wing, development turbulent behind investigated. The then analyzed in detail. results reveal that there strong variation characteristics over...

A numerical study of optimal bandgaps of light absorbers in tandem solar cell configurations is presented with the main focus on dye-sensitized solar cells (DSSCs) and perovskite solar cells (PSCs). The limits in efficiency and the expected improvements of tandem structures are investigated as a function of total loss-in-potential (V(L)), incident photon to current efficiency (IPCE) and fill fa...
