Diffusion-Reaction Modeling of Cu Migration in CdTe Solar Devices
22 Apr 2016 | | Contributor(s):: Da GUO, Tian Fang, Richard Akis, Dragica Vasileska
IWCE 2015 presentation. In this work, we report on development of one-dimensional (1D) finite-difference and two- dimensional (2D) finite-element diffusion-reaction simulators to investigate mechanisms behind Cu- related metastabilities observed in CdTe solar cells . The evolution of CdTe...
Thermionic Escape in Quantum Well Solar Cell
18 Dec 2015 | | Contributor(s):: Nicolas Cavassilas, Fabienne Michelini, Marc Bescond
This theoretical work analyzes the photogeneration and the escape of carrier in InGaN/GaN core-shell nanowires. Our electronic transport model considers quantum behaviors such as confinement, tunneling, electron-phonon scattering and electron-photon interactions. The large lattice mismatch...
Simulation of Organic Solar Cell with Graphene Transparent Electrode
13 Nov 2015 | | Contributor(s):: Paolo Paletti, giacomo ulisse, Giuseppe Iannaccone, Gianluca Fiori
IWCE 2015 presentation. We present a simulation study of the performance of organic solar cell (OSC) exploiting graphene as transparent electrode. The approach is based on a multi-scale/multi-physics simulation framework, which is able to provide relevant information regarding the design...
A Multi-Scale Modeling Approach to Study Transport in Silicon Heterojunction Solar Cells
03 Nov 2015 | | Contributor(s):: Pradyumna Muralidharan, Dragica Vasileska, Stephen M. Goodnick, Stuart Bowden
IWCE 2015 presentation. Abstract and more information to be added at a later date.
A Crash Course in Nanophotonic Simulations
18 Jun 2015 | | Contributor(s):: Peter Bermel
This seminar will cover rapid, scalable computational methods used in simulating optical reflection,transmission, and absorption in complex structures. After a brief survey of the tools available, the S4 simulation tool will be demonstrated in detail.
Failures in Photovoltaic Modules
21 Apr 2015 | | Contributor(s):: Peter Bermel
In this talk, I will discuss some of the major sources of performance degradation for common glass-encapsulated PV modules, including crystalline silicon and thin films. The greatest reliability challenges have occurred in the latter, with recent studies showing that thin-film modules operating...
04 Dec 2014 | | Contributor(s):: Stephan Suckow
This download provides the program "2/3-Diode Fit", which can be used to interactively simulate or fit I-V characteristics of solar cells using different 2- or 3-diode models. Different file formats and batch processing are supported as well as different modes: dark or illuminated...

[Illinois] AVS Meeting 2012: Understanding Atomic-Layer-Deposition Synthesis of Cu 2 ZnSnS 4 Solar Cells
04 Jun 2013 | | Contributor(s):: Sergey V. Baryshev
Cu2ZnSnS4 (CZTS) has recently attracted attention as a light absorber for photovoltaic applications because of its band gap (εg≈1.4 eV), the relative abundance and low cost of its constituent elements (which permits large-scale low-cost module production), and its demonstrated...
Exciton Dynamics Simulator
31 Dec 2012 | | Contributor(s):: Michael Heiber
Simulates the exciton dynamics in organic photovolatic devices
Design of Optoelectronically-active Polymers for Organic Photovoltaic Applications
01 Feb 2013 | | Contributor(s):: Bryan W. Boudouris
Organic photovoltaic (OPV) devices are of great interest due to their promise of providing flexible, lightweight, and inexpensive alternatives to their currently-used inorganic counterparts. However, large-scale implementation of these modules has been hampered due to their relatively low power...
Birck Solar Research Seminar Series
30 Jan 2013 | | Contributor(s):: Peter Bermel
The Solar Research Series includes presentations from researchers at Purdue and leading researchers across the nation on developments in wafer-based, thin-film, organic and cross-cutting technologies in photovoltaics (PV) and related solar power. Results to be presented will include a mixture of...

Nano Solutions to Our Impending Energy Crisis
11 Nov 2012 | | Contributor(s):: Ali Shakouri
In this talk we review some of the advances in nanoscale energy conversion devices and discuss about the challenges and opportunities to provide a clean energy infrastructure. Couple of examples from solar and thermoelectric materials, devices and systems will be given and the scale of the...
ABACUS—Introduction to Semiconductor Devices
When we hear the term semiconductor device, we may think first of the transistors in PCs or video game consoles, but transistors are the basic component in all of the electronic devices we use in...
