A novel use of carbon nanotube networks (CNT) as a semi-transparent layer for better charge collector in GaAs solar cells in order to improve the overall cell performance is presented. The different photovoltaic behaviors have been investigated considering substrate thickness, cell width, dependence between CNT work function and transmittance. CNT layer thickness is found to be optimized at 100nm...
A simple novel and low cost efficient all ZnO based homojunction p-i-n solar cell without any top transparent conductive oxide layer and aback reflector layer are numerically modeled using 2D device simulation tool ATLAS. Optimization of the different layers, doping level and power conversion efficiency of the model has been done. The spectral response such as transmissivity, reflectance, and absorptance...
This paper presents the study of RF characteristics of Graphene based Field Effect Transistor (GFET). The study of characteristic curves is carried out using SILVAVO TCAD tools. The RF parameters which determines the performance of the device in the higher frequency and the effect of downscaling of the device channel length is analyzed and parameters are extracted. This work also presents the effective...
The Cornea-Retinal Potential (CRP) is the main source of the Electrooculogram (EOG) signals. These potential are in small microvolt and required to be amplified upto the applicable and usable level. The place of electrode attachment, the eyeball rotation, the motion of head, the ambient light as well as the conductivity of skin can also vary this signal. These numerous artifacts with power-line interference...
