Public Lecture—Printing Solar Cells for Greener Energy
Lecture Date: Tuesday, January 24, 2012. One of the greatest challenges humanity faces is finding a way to provide the world’s population with clean energy. Since sunlight is our most abundant source of energy, solar cells, which absorb sunlight and create electricity, will become increasingly important over the next several decades. There have been great advances recently using silicon and thin films of semiconductors to make solar cells and solar electricity is just starting to become economically competitive. It is still important, however, to drop the costs further so that it will be possible to utilize even more solar energy. After providing an overview of the solar cell technologies that are currently commercially available, Professor McGehee will describe a relatively new approach that could make it possible to print solar cells in roll-to-roll coating machines similar to those used to make newspapers. Professor McGehee will show how solar cells can be made with organic semiconductors and explain how these cells work. Lecturer: Michael McGehee, Stanford University.
See Through Solar Cells
Fifty years inthe making, solar-power cells are still flat, rigid, and ugly. But new research shows how they could be made lightweight, flexible, and transparent. These innovations could expand solar-cell use to things like solar fabrics and power generating windows. www.sciencentral.com
Argonne tackles solar energy
At Argonne National Laboratory, scientists and engineers are working to improve the solar cell to allow us to capture more of the sun’s energy. Read more: www.anl.gov
