 1.Solar Energy
School: DelftX
Course code:ET3034TUx
Classes start:16 Sep 2013
Course length:8 weeks
Estimated effort:8 hours/week

Prerequisites:

The course is accessible for a broad range of students doing a BSc program.
Some basic knowledge in physics is advantageous and mathematical skills as integration and differentiation are assumed to be known.

ABOUT THIS COURSE
The course Solar Energy will teach you to design a complete photovoltaic system. The course will introduce you to the technology that converts solar energy into electricity, heat and solar fuels with a main focus on electricity generation. Photovoltaic (PV) devices are presented as advanced semiconductor devices that deliver electricity directly from sunlight. The emphasis is on understanding the working principle of a solar cell, fabrication of solar cells, PV module construction and the design of a PV system. You will understand the principles of the photovoltaic conversion (the conversion of light into electricity). You will learn about the advantages, limitations and challenges of different solar cell technologies, such as crystalline silicon solar cell technology, thin film solar cell technologies and the latest novel solar cell concepts as studied on lab-scale. The course will treat the specifications of solar modules and show you how to design a complete solar system for any particular application. The suitable semiconductor materials, device physics, and fabrication technologies for solar cells are presented. The guidelines for design of a complete solar cell system for household application are explained. Alternative storage approaches through solar fuels or conversion of solar energy in to heat will be discussed. The cost aspects, market development, and the application areas of solar cells are presented.

After completion of the course, you will be able to:

a) explain the various concepts to convert solar energy in to electricity, heat and solar fuels

b) explain the physical working principles of photovoltaic conversion in solar cells

c) recognize and describe the various solar cell technologies, their current status and future technological challenges

d) analyze the performance of solar cells and modules

e) design a complete photovoltaic system for any particular application on paper

To celebrate this first MOOC on Solar Energy the best student of the course will be invited to the Delft University of Technology for a Delft Solar Energy Center course of one week, to get hands-on lab experience with all the concepts taught in this Solar Energy course.

Education method

The class will consist of a collection of lecture videos, each between eight and twelve minutes in length. The course contains exercises and assignments, which are additional to the video lectures. The best student of the course will be invited to the Delft University of Technology for a Photovoltaics Lab course of one week, to get hands-on lab experience with all the concepts taught in this Solar Energy course.

2.Foundations of Computer Graphics

 
School: UC BerkeleyX
Course code:CS-184.1x
Classes start:7 Oct 2013
Course length:6 weeks
Estimated effort:12 hours/week

Prerequisites:

  1. Solid C/C++ programming background (Java is ok too; you will pick up C++).
  2. Access to a relatively up-to-date computer (Windows, Mac OSX or Linux)
  3. Solid high school mathematics; a review of the relevant linear algebra is included in the first segment
ABOUT THIS COURSE
CS184.1x teaches the Foundations of Computer Graphics. Students will make images of 3D scenes in real-time, and with offline raytracing. This course runs for 6 weeks and consists of four segments. Each segment includes an individual programming assignment:
  1. Overview and Basic Math (Homework 0: 10% of grade)
  2. Transformations (Homework 1: 20% of grade)
  3. OpenGL and Lighting (Homework 2: 35% of grade)
  4. Raytracing (Homework 3: 35% of grade)
This term, students who earn a total score of 50% or greater will have passed the course and may obtain a free honor code certificate from BerkeleyX.
