Developing new solar cells - cheaper, or more efficient
Kavli Medal and Lecture by Professor Neil Greenham, University of Cambridge.
The next generation of solar cells use strongly absorbing materials such as polymers that can be deposited cheaply over large areas by printing, thereby offering a feasible way to install solar power on an affordable scale.
This lecture will describe how we can improve the performance of these devices by controlling the complex nanostructures that allow charges to be extracted from the active layer. It will present a new approach that might break the 34% efficiency limit that applies to all simple solar cells, by extracting energy from the blue and green parts of the solar spectrum that is normally wasted.
Professor Greenham was awarded the Kavli Medal and Lecture for his exceptional work on hybrid materials, combining polymer semiconductors with inorganic nanoparticles, and their use in printable solar cells.
