Nanobeads of zinc oxide with rhodamine B dye as a sensitizer for dye sensitized solar cell application

Morphology evolution of ZnO thin films from aqueous solutions and their application to liquefied petroleum gas (LPG) sensor

“…ZnO is a promising candidate for optoelectronics and piezoelectric applications due to its wide band gap (3.37 eV), a large exciton binding energy (60 meV) at room temperature and its non-centro-symmetry in the wurtzite structure [2]. ZnO can be grown richest variety of nanostructures [3] and is expected to be the next most important material for a variety of practical applications such as TCOs [4], photodetectors [5], UV-laser [6], gas sensors [7,8], buffer layers in CIS solar cells [9], n-type window layer in extremely thin absorber (ETA) solar cells [10], and as an electrode in DSSCs [11,12]. Until today, there has been a prevailing need for efficient, low temperature and lowcost deposition methods for thin films as technological industrial applications.…”

Synthesis of garland like ZnO nanorods and their application in dye sensitized solar cells

“…Noshin Mir et al [7] have reported 1.03% efficiency for ZnO nanoflower based dye sensitized solar cell. Efficiency of 1.26% has been reported by Baviskar et al [8] for ZnO based dye sensitized solar cells. Ahmad Umar et al [9] have synthesized ZnO with flower like structure and have reported an efficiency of 1.38%.…”

“Basic idea, advance approach”: Efficiency boost by sensitization of blended dye on chemically deposited ZnO films

“…Our earlier report shows 1.26 % power conversion efficiency for chemically synthesized ZnO nanobeads with metal free rhodamine B dye as sensitizer [22]. Recently, Nakajima et al discuss the wavelength-dependence of azo dyes sensitized on TiO2 [23].…”
