Multicrystalline silicon wafers, widely used in commercial photovoltaic cell production, traditionally give much poorer performance than monocrystalline wafers (the previously highest laboratory devices have solar energy conversion efficiencies of 18.6% and 24.0%, respectively). A substantially improved efficiency for a multicrystalline 19.8% is reported together with an incremental improvement to 24.4%. The results from enshrouding surfaces thermally grown oxide reduce their detrimental...
Due to its indirect bandstructure, bulk crystalline silicon is generally regarded as a poor light emitter. In contrast this common perception, we report here on surprisingly large external photoluminescence quantum efficiencies of textured wafers up 10.2% at T=130 K and 6.1% room temperature. Using theoretical model calculate the escape probability for internally generated photons, can conclude from these experimental figures that radiative recombination or internal luminescence efficiency...

This paper presents an innovative method to analyse and design optimal energy management strategy for a power-split power train hybrid vehicle. A dynamical system theory is introduced formulate the problem of vehicle control that incorporates both continuous discrete dynamics. The sequential quadratic programming proposed optimise distribution. dynamic employed determine operating mode transitions with fuel efficiency satisfactory drivability. An expert rule-based fuzzy are developed...
RedOx-based magnetohydrodynamic (MHD) flows in three-dimensional microfluidic channels are investigated theoretically with a coupled mathematical model consisting of the Nernst-Planck equations for concentrations ionic species, local electroneutrality condition electric potential, and Navier-Stokes flow field. A potential difference is externally applied across two planar electrodes positioned along opposing walls microchannel that filled dilute RedOx electrolyte solution, Faradaic current...
High minority carrier lifetimes of a few milliseconds have been demonstrated both on CZ and FZ n-type silicon substrates. It is particularly interesting that the phosphorus doped wafers give nearly as high those from best p-type materials. This gives good potential for very performance 21.1% 21.9% efficiencies are reported PERT (passivated emitter, rear totally-diffused) cells fabricated these mono-crystalline substrates, respectively. open-circuit voltages approaching 700 mV by cells....
Co-doped ZnO films with nanorod structures are fabricated by a simple wet chemical method combined an electrodeposition process on the ITO substrates. This is proved to be repeatable, low-cost and high-yield route synthesize magnetical nanocrystals. SEM measurements show structure. X-ray diffraction (XRD) spectra demonstrate that nanorods crystals (1 0 0) 1) preferential orientation. photoelectron spectroscopy results indicate Co distributed in nanorods. The magnetic properties of were...
Newly fabricated semiconductor Bi2O2Se films exhibit excellent electron transport and optical properties, with potential application in optoelectronics. In this work, using first-principle calculations combined the modified Becke-Johnson exchange potential, we have systematically investigated electronic, transport, properties of bulk Bi2O2Se. Our shown that external strain can effectively tune electronic bandgap response that, particular, appropriate lead to a transition from an indirect...
The fracture behaviors of monolayer phosphorene (MP) with and without a grain boundary (GB) have been explored by molecular dynamics (MD) simulations. Firstly, in the case perfect MP, mostly happens on bond zigzag direction when suffering random loading. With existence GB, crack propagates perpendicular to GB different ways under parallel tension whereas it along GB. Then, we found that both strength strain decrease increasing temperature making more likely at relatively high temperatures....
