Light Management Optimization of Upconversion-Based Solar Cell Using Genetic Algorithms

J. Bork1, M. F. Doty1, J. M. O. Zide1
1University of Delaware, Newark, DE, USA

We demonstrate a COMSOL Multiphysics®-based approach to light management for upconversion-based solar cells (UBSCs). Single-junction solar cells are of high importance to sustainable energy production, however the cells are limited in their performance by the bandgap of the solar cell. ... En savoir plus

Aquifer Pumping Test Evaluation: 1D Classical vs. 2D Numerical Solutions

E. Holzbecher1
1German University of Technology in Oman

In a pumping test the drawdown of the water table in a piezometer is recorded, as response to pumping from a nearby well. Pumping tests belong into the common toolbox of hydro-geologists, used to obtain basic parameters for aquifer characterization. There are various approaches to ... En savoir plus
