Full Spectrum Diffused and Beamed Solar Energy Application Using Optical Fibre [PDF]

open access: yesarXiv, 2007
Existing solar energy application systems use small fraction of full spectrum of solar energy. So attempts are made to show how full spectrum solar energy can be used for diffused and beamed form of incident solar energy. Luminescent Solar Concentrator (LSC) principle with optical fibre in diffused sun light and dielectric mirror separation technique ...

Selective Reduction Laser Sintering: A New Strategy for NO2 Gas Detection Based on In2O3 Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
This research utilizes selective reduction laser sintering (SRLS) to engineer In2O3 NPs for flexible NO2 sensors. The introduction of oxygen vacancy defects enhances sensor performance, offering excellent responsiveness, rapid response/recovery, superior selectivity, low detection limit, and long‐term stability.

A possible solution to the solar neutrino problem: Relativistic corrections to the Maxwellian velocity distribution [PDF]

open access: yesarXiv, 2001
The relativistic corrections to the Maxwellian velocity distribution are needed for standard solar models. Relativistic equilibrium velocity distribution, if adopted in standard solar models, will lower solar neutrino fluxes and change solar neutrino energy spectra but keep solar sound speeds. It is possibly a solution to the solar neutrino problem.

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

open access: yesAdvanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Solar Thermal Energy Conversion Enhanced by Selective Metafilm Absorber under Multiple Solar Concentrations at High Temperatures [PDF]

open access: yes, 2019
Concentrating solar power, particularly parabolic trough system with solar concentrations less than 50, requires spectrally selective solar absorbers that are thermally stable at high temperatures of 400degC above to achieve high efficiency. In this work, the solar-thermal performance of a selective multilayer metafilm absorber is characterized along ...
