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 electron-hole pairs. This tutorial focussing on recombination losses in crystalline silicon solar cells under short-circuit and open-circuit conditions.

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 Lecture 1: Introduction to Photovoltaics

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.

Lecture 10: Case study-Near-equilibrium Transport in Graphene

Near-equilibrium transport in graphene as an example of how to apply the concepts in lectures 1-8.

ECE 656: Electronic Transport in Semiconductors (Fall 2011)

29 Aug 2011 | Courses | Contributor(s): Mark Lundstrom

This course is about how charge flows in semiconductors with an emphasis on transport in nanoscale devices. The objective is to develop a broad understanding of basic concepts. The course is designed for those who work on electronic materials and devices – whether they are...

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 8: Measurements

16 Aug 2011 | Online Presentations | Contributor(s): Mark Lundstrom

A brief introduction to commonly-used techniques, such as van der Pauw and Hall effect measurements.

Lecture 7: The Boltzmann Transport Equation

Semi-classical carrier transport is traditionally described by the Boltzmann Transport Equation (BTE). In this lecture, we present theBTE, show how it is solved, and relate it to the Landauer Approach usedin these lectures

Lecture 6: An Introduction to Scattering

In this lecture, we show how the mean-free-path (mfp) is related to thetime between scattering events and briefly discuss how the scattering time is related to underlying physical processes.

Lecture 5: Thermoelectric Effects - Mathematics

Beginning with the general model for transport, we mathematically deriveexpressions for the four thermoelectric transport coefficients:(i) Electrical conductivity,(ii) Seebeck coefficient (or "thermopower"),(iii) Peltier coefficient,(iv) Electronic heat conductivity.

Near-Equilibrium Transport: Fundamentals and Applications

28 Jul 2011 | Courses | Contributor(s): Mark Lundstrom

Engineers and scientists working on electronic materials and devicesneed a working knowledge of "near-equilibrium" (also called "linear"or "low-field") transport. The term "working knowledge" meansunderstanding how to use theory in practice. Measurements ofresistivity, conductivity, mobility,...

Lecture 4: Thermoelectric Effects-Physical Approach

28 Jul 2011 | Online Presentations | Contributor(s): Mark Lundstrom

The effect of temperature gradients on current flow and how electrical currents produce heat currents are discussed.

Lecture 3: Resistance-Ballistic to Diffusive

The resistance of a ballistic conductor and concepts, such as the quantumcontact resistance, are introduced and discussed. The results are then generalized to treat transport all the way from the ballistic to diffusive regimes.
