Course Purpose
This course provides an overview of the global energy system, relates fossil fuel consumption to anthropogenic climate change, and outlines alternatives that promote long term environmental sustainability. Topics include basic climate science, energetics of natural and human systems, energy in fossil-fueled civilization, the impact of anthropogenic CO2 emissions on climate, and technology and public policy options for addressing the climate challenge. While the course is highly interdisciplinary, the approach is quantitative with a strong focus on science and engineering.
Course Objectives
By the end of the course, students will be able to (1) apply concepts drawn from ecology, physics, economics, and engineering to analyze energy resources and technologies, (2) explain how human activity affects climate, (3) outline the pros and cons of various low carbon energy technologies using quantitative methods, (4) build and apply impulse-response function models of climate change to relate emissions to atmospheric concentrations and impacts, and (5) describe public policy and adaptation options for dealing with climate change.
Course Objective
After taking this course, the student should be able to analyze and design fundamental analog integrated circuit blocks at the transistor level, including single and multi-stage amplifiers, bias networks, and both elementary and advanced operational amplifiers. The student should be able to determine the effect of feedback on circuit operation and then design appropriate feedback networks for amplifier and bias circuits. Finally, the student should be able to efficiently use electronic design tools for circuit design and analysis.

Course Objectives
This first-level graduate course is intended to develop an understanding of Power Electronics and switching mode power converters for various AC and DC applications. This course is intended to teach the fundamentals of power conversion and will cover the design, analysis, modeling, and control of all types of power converters – such as dc-dc converters, dc-ac inverters, ac-dc rectifiers/converters and also introduce the preliminary concepts of direct ac-ac converters. This course will also include interface and control considerations of power converters to single-phase and three-phase ac systems and discuss utility applications of power electronic converters – including power quality and FACTS (Flexible AC Transmission Systems).
The students will develop skills in the complete design of these power converters through a project – which will be focused on a practical design of dc-dc converters.
This will be an important course for an understanding of renewable energy interface to the grid, power converters for ac- and dc motor drives, and power electronics devices and their controls.

This course studies the fundamental and recent advances of energy harvesting from two of the most abundant sources, namely solar and thermal energy. The first part of the course focuses on photovoltaic science and technology. The characteristics and design of common types of solar cells are discussed, and the known approaches to increasing solar cell efficiency will be introduced. After the review of the physics of solar cells, we will discuss advanced topics and recent progress in solar cell technology. The second part of the course is focused on the thermoelectric effect. The basic physical properties, Seebeck coefficient, electrical and thermal conductivities are discussed and analyzed through the Boltzmann transport formalism. Advanced subjects such as carrier scattering time approximations in relation to dimensionality and the density of states are studied. Different approaches for further increasing efficiencies are discussed, including energy filtering, quantum confinement, size effects, band structure engineering, and phonon confinement.
The course offers the expertise students need in both areas of photovoltaic and thermoelectrics and prepares them for graduate research or to work in solar cell manufacturing or thermoelectric industry. The goal is to prepare the students with the fundamentals and advanced topics of solid-state energy conversion. In the first part of the course, the science and engineering of various types of solar cells are introduced. The students will learn how the efficiency of solar cells are improved from fundamental points of view. Concepts such as tandem, multi-barrier, intermediate band, quantum dot intermediate band, hot carriers, Plasmonics, and the effect of temperature will be discussed. In the second part, concepts in thermoelectrics, such as coefficient of performance, multi-stage devices, Seebeck coefficient, effect of temperature and density of states, Thomson effect, specific heat, Dulong-petit limit, Debye and Einstein models, phonon scattering mechanisms, and thermal conductivity are conveyed through physical equations and pictorial descriptions.
