Solar Cells Lecture 1: Introduction to Photovoltaics
19 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
An introduction to solar cells covering the basics of PN junctions,
optical absorption, and IV characteristics. Key technology options and economic considers are briefly presented.

Solar Cell Fundamentals
19 Aug 2011  Courses  Contributor(s): Mark Lundstrom, J. L. Gray, Muhammad A. Alam
The modern solar cell was invented at Bell Labs in 1954 and is currently receiving renewed attention as a potential contribution to addressing the world's energy challenge. This set of five tutorials is an introduction to solar cell technology fundamentals. It begins with a broad overview of solar cells and continues with a discussion of carrier generation and recombination in silicon solar cells. The tutorials continue with an overview of solar cell modeling and …

Solar Cells Lecture 2: Physics of Crystalline Solar Cells
19 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
Solar cell performance is determined by generation and recombination of electronhole pairs. This tutorial focussing on recombination losses in crystalline silicon solar cells under shortcircuit and opencircuit conditions.

Lecture 10: Case studyNearequilibrium Transport in Graphene
19 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
Nearequilibrium transport in graphene as an example of how to apply the concepts in lectures 18.

Lecture 7: The Boltzmann Transport Equation
17 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
Semiclassical carrier transport is traditionally described by the
Boltzmann Transport Equation (BTE). In this lecture, we present the
BTE, show how it is solved, and relate it to the Landauer Approach used
in these lectures

Lecture 9: Introduction to Phonon Transport
17 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
This lecture is an introduction to phonon transport. Key similarities and differences between electron and phonon transport are discussed.

Lecture 5: Thermoelectric Effects  Mathematics
16 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
Beginning with the general model for transport, we mathematically derive
expressions for the four thermoelectric transport coefficients:
(i) Electrical conductivity,
(ii) Seebeck coefficient (or "thermopower"),
(iii) Peltier coefficient,
(iv) Electronic heat conductivity.

Lecture 6: An Introduction to Scattering
16 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
In this lecture, we show how the meanfreepath (mfp) is related to the
time between scattering events and briefly discuss how the scattering
time is related to underlying physical processes.

Lecture 8: Measurements
16 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
A brief introduction to commonlyused techniques, such as van der Pauw and Hall effect measurements.

Lecture 2: General Model for Transport
28 Jul 2011  Online Presentations  Contributor(s): Mark Lundstrom
Datta's model of a nanodevice is introduced as a general way of describing nanodevices as well, as bulk metals and semiconductors.

Lecture 3: ResistanceBallistic to Diffusive
28 Jul 2011  Online Presentations  Contributor(s): Mark Lundstrom
The resistance of a ballistic conductor and concepts, such as the quantum
contact resistance, are introduced and discussed. The results are then
generalized to treat transport all the way from the ballistic to
diffusive regimes.

Lecture 4: Thermoelectric EffectsPhysical Approach
28 Jul 2011  Online Presentations  Contributor(s): Mark Lundstrom

NearEquilibrium Transport: Fundamentals and Applications
28 Jul 2011  Courses  Contributor(s): Mark Lundstrom
Engineers and scientists working on electronic materials and devices
need a working knowledge of "nearequilibrium" (also called "linear"
or "lowfield") transport. The term "working knowledge" means
understanding how to use theory in practice. Measurements of
resistivity, conductivity, mobility, thermoelectric parameters as well
as Hall effect measurements are commonly used to characterize
electronic materials. Thermoelectric effects are the basis for
important devices, and …
