Hybrid Dielectric-Metallic Back Reflector for Amorphous Silicon Solar Cells
Energies, 2010 In this paper, we present the design and fabrication of hybrid dielectric-metallic back surface reflectors, for applications in thin film amorphous silicon solar cells. Standard multilayer distributed Bragg reflectors, require a large number of layers in

Novel perovskite solar cell with Distributed Bragg Reflector
PLOS ONE, 2021 This paper reports numerical modeling of perovskite solar cell which has been knotted with Distributed Bragg Reflector pairs to extract high energy efficiency. The geometry of the proposed cells is simulated with three different kinds of perovskite materials including CH3NH3PbI3, CH3NH3PbBr3,and CH3NH3SnI3.

Subtle design changes control the difference in colour reflection from the dorsal and ventral wing-membrane surfaces of the damselfly Matronoides cyaneipennis. [PDF]
, 2016 The hind wings of males of the damselfly Matronoides cyaneipennis exhibit iridescence that is blue dorsally and green ventrally. These structures are used semiotically in agonistic and courtship display.

Polarization properties in the transition from below to above lasing threshold in broad-area vertical-cavity surface-emitting lasers [PDF]
, 2009 For highly divergent emission of broad-area vertical-cavity surface-emitting lasers (VCSELs) a rotation of the polarization direction by up to 90 degrees occurs when the pump rate approaches the lasing threshold.
