Modeling of dual-metal Schottky contacts based silicon micro and nano wire solar cells
(
Elsevier B.V.
, 2014 , Article)
We study solar cell properties of single silicon wires connected at their ends to two dissimilar metals of different work functions. Effects of wire dimensions, the work functions of the metals, and minority carrier lifetimes ...
Effect of outdoor temperature on the power-conversion efficiency of newly synthesized organic photosensitizer based dye-sensitized solar cells
(
Elsevier B.V.
, 2018 , Article)
In this work, organic photosensitizer has been synthesized for dye-sensitized solar cells (DSSCs). The solar cells then fabricated have been characterized by photocurrent-voltage characteristics and electrochemical impedance ...
Biotransformation of carbon dioxide in bioelectrochemical systems: State of the art and future prospects
(
Elsevier
, 2017 , Article)
Carbon dioxide (CO2) utilization/recycling for the production of chemicals and gaseous/liquid energy-carriers is a way to moderate the rising CO2 in the atmosphere. One of the possible solutions for the CO2 sequestration ...
Zero-bias photocurrents in highly-disordered networks of Ge and Si nanowires
(
Institute of Physics Publishing
, 2015 , Article)
Semiconducting nanowire (NW) devices have garnered attention in self-powered electronic and optoelectronic applications. This work explores and exhibits, for the first time for visible light, clear evidence of the zero-biased ...
Photoresponse of silicon with asymmetric area contacts
(
Institute of Physics Publishing
, 2016 , Article)
We report on high performance metal-semiconductor-metal (MSM) photosensors based on asymmetric metal pad areas. The reported devices require a single-step metal deposition, and exhibit large photo response even under ...
A comparison of the redox properties of vanadia-based mixed oxides
(
American Chemical Society (ACS)
, 2015 , Article)
The thermodynamics of oxidation and reduction were investigated for a series of vanadium-containing oxides, including CeVO4, LaVO 4, ZrV2O7, Mg3(VO4) 2, CrVO4, AlVO4, and V2O 5, in the temperature range between 873 and 973 ...
Effect of the length of silicon nano-dot/wire on band gap
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2014 , Conference Paper)
We will report on the role of the length of silicon nanowire (SNW) in determining the band gap of a structure. We find that the band gap decreases with SNW length for the same diameter and approaches the band gap for an ...
Oxygen passivation as effective technique for tailoring the nature of band gap of silicon nanowires
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2015 , Conference Paper)
Silicon nanowires have been subjected to several experiential and theoretical studies, including chemical tuning with different substituents aiming to tailor the band gap as well as increasing optical absorption efficiency ...
CO2 Reduction to Renewable Hydrocarbon Fuel - Mimicking Natural Photosynthesis
(
Springer Nature
, 2017 , Article)
We report on a wide-range Density Functional Theory (DFT) investigation of the g-C3N4 photocatalysis systems combined with metals/nonmetals, especially those available in plants and involved in the natural photosynthesis ...
