Quantum Dot: Carrier Relaxation Dynamics and its Application in Solar Cell

This is a review paper i’ve written last semester. The abstract is as follows

Quantum dot solar cell has emerged as a new photovoltaic technology that brings us the possibility of breaking through the present maximum attainable Shockley-Quiesser efficiency. This report first addresses the main problems underlying the efficiency limitation of the current photovoltaic technology. These problems are due to the various relaxation mechanisms of the electron-hole pair in the semiconductor. We then focus the discussion on how the unique properties of quantum dot can result in phonon bottleneck effect and enhance impact ionization during the carrier relaxation process. Lastly, one possible quantum dot solar cell configuration namely the quantum dot sensitized solar cell, is highlighted. Quantum dot solar cell has strong potential to make solar energy a cheap and high-efficieny renewable energy source in the future.

I have just realised wordpress supports . This is so cool, i’m gonna write more things on my blog from now onwards.
