Simulation of Optical Properties of the Si/SiO₂/Al Interface at the Rear of Industrially Fabricated Si Solar Cells

Y. Yang[1], and P. Altermatt[1,2]
[1]Institute for Solar Energy Research Hamelin (ISFH), Emmerthal, Germany
[2]Dep. Solar Energy Research, Inst. Solid-State Physics, Leibniz University of Hanover, Germany

The specular and diffuse reflection properties of sunlight at the rear surface of silicon solar cells with various degrees of roughness are computed by solving the Maxwell and material equations in two dimensions, using the COMSOL RF Module. The model is tested on planar Si/SiO2/air ... En savoir plus

Air Convection on a Micro Hotplate Gas Sensor

S. Gidon[1], M. Brun[1], S. Nicoletti[1], P. Barritault[1]
[1]Commissariat Energie Atomique, LETI, Minatec Campus, Grenoble, France

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared ... En savoir plus

Real-Time Prediction of Incipient Failure in Working Fluids

R. W. Pryor, Ph.D.¹
¹Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

Working fluids (engine oil, transmission fluid, hydraulic fluid, coolants, etc.) become contaminated in use. To ensure that the equipment is not damaged by the contaminated fluid, the fluid is typically removed and replaced periodically. For large groups of machines, the used fluid is ... En savoir plus

Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes

C. Hansen [1],
[1] Electro Scan Inc., Sacramento, CA, USA

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... En savoir plus

Finite Element Modeling a Redox-Enzyme-Based Electrochemical Biosensor

Y. Huang[1], and A. Mason[1]
[1]Electrical and Computer Engineering, Michigan State University, East Lansing, Michigan, USA

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak ... En savoir plus
