Organic semiconductor-based photonic crystals for solar cell arrays: band gap and optical properties

Abstract

Cataloged from PDF version of article.Photonic crystals (PCs) hold great potential for designing new optical devices because of the possibility of the manipulation of light with PCs. There has been an increase in research on tuning the optical properties of PCs to design devices. We design organic semiconductor-based PC structures and calculate optical properties using the plane wave expansion method and finite-difference time-domain method in an air background for a hexagonal lattice. We showed the possibility of the solar cell arrays for a 2D PC cavity on an organic semiconductor base infiltrated with a nematic liquid crystal. E7 type has been used as a nematic liquid crystal and 4,4-Bis[4-(diphenylamino) styryl]biphenyl as an organic semiconductor material

Analysis of Photonic Crystal Tuned by Nematic Liquid Crystals

“…In recent years, novel investigations have reached a viewpoint of LCs owing to the tunable light. Refractive indices of LCs can be changed by rotating LCs' directors [15][16][17].…”
