The Imaging Challenge
Solar cells are large-area semiconductor devices with typical side lengths of 15.6cm. Local loss mechanisms often reduce the energy to current conversion efficiency of solar cells. Optical characterization techniques that are capable of providing spatially resolved information about the performance of a solar cell are therefore of great importance, not only for research and development, but also as a process control tool in the solar cell production lines.

The Solution
Unfortunately, most of the present characterization techniques providing spatially resolved information are very slow ...
