From the wide spectrum of potential applications of graphene, ranging from transistors and chemical sensors to nanoelectromechanical devices and composites, the field of photonics and optoelectronics is believed to be one of the most promising. Indeed, graphene's suitability for high-speed photodetection was demonstrated in an optical communication link operating at 10 Gbit s(-1). However, the ...
This paper deals with a 3 dimensional modeling of a polycrystalline silicon solar cell in steady state under constant multispectral illumination. After the resolution of the continuity equation the expression of photocurrent density and photovoltage are presented and the impact of the recombination velocity at grain boundaries and grain size on these parameters will also be considered.

An unprecedented octahedral {Cd(30)} nanocage supported by twelve pendant-armed tetraacetate macrocyclic ligands was synthesized through the reaction of macrocyclic tetraethyl ester and Cd(OAc)(2)·2H(2)O in a 1 : 2 stoichiometry, where the surface photovoltage and photoluminescent properties have been studied for the nanocage.
We have synthesized a highly efficient organic dye for a dye-sensitized solar cell; the overall solar-to-energy conversion efficiency was 9.1% at AM 1.5 illumination (100 mW cm(-2)): short-circuit current density (J(sc)) = 18.1 mA cm(-2), open circuit photovoltage (V(oc)) = 743 mV and fill factor (ff) = 0.675.
