The technologies used to produce solar cells and photovoltaic modules are advancing to deliver highly efficient and flexible solar panels. In this course you will explore the main PV technologies in the current market. You will gain in-depth knowledge about crystalline silicon based solar cells (90% market share) as well as other up and coming technologies like CdTe, CIGS and Perovskites. This course provides answers to the questions: How are solar cells made from raw materials? Which technologies have the potential to be the major players for different applications in the future?

In the electrical engineering, solid-state materials and the properties play an essential role. A thorough understanding of the physics of metals, insulators and semiconductor materials is essential for designing new electronic devices and circuits. After short introduction of the IC fabrication process, the course starts with the crystallography. This will be followed by the basic principle of the quantum mechanics, the sold-state physics, band-structure and the relation with electrical properties of the solid-state materials. When the material physics has been throughly understood, the physics of the semiconductor device follows quite naturally and can be understood quickly and efficiently. Study Goals: The student can 1) determine the crystal structure, the density of atoms and the Miller indices of a crystal, 2) apply Schrodinger's wave equation to various potential functions and derive a probability of finding electrons, 3) discuss the concept of energy band formation and difference of material properties in terms of the band, 4) derive the concentrations of electron and holes with a given temperature in terms of Fermi energy, and 5) can discuss drift, diffusion and scattering of carriers in a semiconductor under various temperature and impurity concentrations.

A transition to sustainable energy is needed for our climate and welfare. In this engineering course, you will learn how to assess the potential for energy reduction and the potential of renewable energy sources like wind, solar and biomass. You’ll learn how to integrate these sources in an energy system, like an electricity network and take an engineering approach to look for solutions and design a 100% sustainable energy system.

Discusses a wide variety of processes and materials from the viewpoint of their fundamental physical and chemical properties. Specific topics: cold welding, adhesive bonding, diffusion bonding, soldering, brazing, flames, arcs, high-energy density heat sources, solidification, cracking resistance, shielding methods, and electric contacts. Emphasis on underlying science of a given process rather than a detailed description of the technique or equipment. Meets with first half of subject 3.371J in Fall Term; videotaped instruction in other terms.

" In 2004, the Ansari X PRIZE for suborbital spaceflight captured the public's imagination and revolutionized an industry, leveraging a $10M prize purse into over $100M in innovation. Building from that success, the X PRIZE Foundation is now developing new prizes to focus innovation around "Grand Challenge" themes, including genomics, energy, healthcare, and education. This course will examine the intersection of incentives and innovation, drawing on economic models, historic examples, and recent experience of the X PRIZE Foundation to help develop a future prize in Energy Storage Technologies."
