| Notes: | IAS Distinguished Lecture. Abstract: With continual progress in solar cells, we are now approaching theoretical efficiency limits. As the efficiency rises, photon management becomes more important than electronic transport properties. The theoretical Shockley-Queisser efficiency limit implicitly assumes perfect extraction of luminescent photons from the semiconductor film. We know from Light-Emitting Diodes, that this is actually very difficult to achieve. A very good solar cell also needs to be an excellent LED. Prof Yablonovitch's work has covered a broad variety of topics: nonlinear optics, laser-plasma interaction, infrared laser chemistry, photovoltaic energy conversion, strained-quantum-well lasers, and chemical modification of semiconductor surfaces. Currently his main interests are in optoelectronics, high speed optical communications, high efficiency light-emitting diodes and nano-cavity lasers, photonic crystals at optical and microwave frequencies, quantum computing and quantum communication.
