SYNOPSIS
Photovoltaics, the direct conversion of sunlight to electricity, is the fastest growing technology for electricity generation. "First generation" products use the same silicon wafers as in microelectronics. "Second generation" thin-films improves the economics by eliminating material costs. Third-generation photovoltaic cells are cells that are potentially able to overcome the Shockley-Queisser limit of power efficiency. Among these cells a particular attention is now given to quantum dot solar cells that use nanocrystals as the absorbing material. Nanocrystals have bandgaps that are tunable across a wide range of energy levels by changing their size. This property makes nanocrystals attractive since they can be used to improve efficiency by harvesting multiple portions of the solar spectrum. The session is aimed at presenting latest results in this field, including down-shifting, up-conversion and carrier multiplication effects.
