Staying up to date with the latest technology is very important in a fast changing field like solar energy. Today’s silicon based solar cells may give way to flexible organic cells or even liquid quantum dot cells. Even if you are not planning to be a solar researcher you need to stay current with the next big thing in your chosen field of work.
In the video you will learn all about quantum dot solar cell technology from a U.S. D.O.E funded project as well as actually learn how to assemble the components of a liquid quantum dot solar cell into a working device.
Pay attention to the personal protective safety equipment and procedures that are followed during the assembly process. This takes place in a laboratory environment so safety and cleanliness are very important.
Here is a common definition of a quantum dot solar cell. ( Wikipedia )
A quantum dot solar cell is a solar cell design that uses quantum dots as the absorbing photovoltaic material. It attempts to replace bulk materials such as silicon, copper indium gallium selenide (CIGS) or CdTe. Quantum dots have bandgaps that are tunable across a wide range of energy levels by changing the dots’ size. In bulk materials the bandgap is fixed by the choice of material(s). This property makes quantum dots attractive for multi-junction solar cells, where a variety of materials are used to improve efficiency by harvesting multiple portions of the solar spectrum.
In this video, Prashant V. Kamat, Radiation Laboratory and Department of Chemistry and Biochemistry, University of Notre Dame, Notre Dame, Indiana, discusses his Perspective published in issue 6 of the Journal of Physical Chemistry Letters.
As you can see there is so much to learn when it comes to solar energy, especially since so much is changing so fast. The materials and process are being adapted for new designs as well as faster manufacturing which is not only lowering the costs but making them more efficient and reliable at the same time. Solar energy in the next 50 years will undergo so many changes and advancements. It would be a fascinating area to have as a career.
