Optimisation of concentrator in the solar photonic optoelectronic transformer: optical gain analysis

Mirror symmetrical dielectric totally internally reflecting concentrator for building integrated photovoltaic systems

“…The CAD model of the MSDTIRC is placed at a distance of 35cm from the source and a photo detector is attached at the exit aperture of the concentrator. Similar to the analysis in [5] and [22], it has been found in this analysis that the optical gain reaches a maximum value when the rays are fired at normal incidence, and this value reduces gradually when the angle of incidence increases until it is equal to the value of the acceptance angle. Beyond the acceptance angle of the concentrator, the gain should decrease greatly.…”

“…The optical concentration gain is defined as the ratio of the irradiance at the photo detector with a concentrator placed in front of it to that of a photo detector without the concentrator [22].…”

Low carbon strategies for sustainable bio-alkane gas production and renewable energy

“…A 15-fold solar concentration is required to generate the required blue light intensities which could be met using existing solar concentration technologies, similar to the Australian National University parabolic trough or the Entech Incorporated Fresnel lens (each achieving 30-fold concentration). 57 To allow diurnal propane production, light supplementation via LEDs could be supplied outside daylight hours. Alternatively, Halomonas could be engineered to include an alternative non-light requiring ADO-dependent pathway from valine (Fig.…”

Temperature Performance Evaluation of Parabolic Dishes Covered with Different Materials in Iwo, Nigeria

“…The intensity of solar radiation per unit time on a unit surface outside the earth's atmosphere is known as "solar constant" Manav et al, (2015). Muhammad-Sukki et al, (2012), reported that solar energy can be converted into thermal energy either by flat plate collector or a concentrator. Different types of concentrators include parabolic trough collector, parabolic dish and linear Fresnel reflector.…”
