(
Elsevier Ltd
, 2016 , Article)
The utilization of silicon nanostructures, from quantum dots to nanowires, for photovoltaic applications depends on understanding the effect of their physical structure on their optical absorption properties. In this work, ...
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 ...
Investigating the impact of dynamic merge control strategies on driving behavior on rural and urban expressways – A driving simulator study
(
Elsevier Ltd
, 2019 , Article)
Harsh decelerations and abrupt lane changes of drivers on the outer expressway lane in response to merging platoon vehicles from on-ramps increase the crash- and congestion risk on expressways. Several merge control ...
Speed perception and actual speed in a driving simulator and real-world: A validation study
(
Elsevier Ltd
, 2019 , Article)
Background: Driving simulators have become an effective research tool in traffic safety, but the validity of results obtained in simulated environments remains a debated issue of high importance. Objective: The objective ...
The relation between driving errors and executive functioning in intellectually able young novice drivers with autism
(
Elsevier Ltd
, 2019 , Article)
Driving is a complex, goal-directed task. ASD can be related to impairments in executive functioning (EF), which may interfere with driving. This study aimed to investigate (1) if 16 young novice drivers with ASD exhibited ...
