Tech News 1: Predicting solar cell performance from terahertz and microwave spectroscopy

[bob_turner]

The most important properties of a semiconductor to be used as a solar cell include the mobility and lifetime of electrons and "holes". Both quantities can be measured without contacts with spectroscopic methods using terahertz or microwave radiation. However, measurement data found in literature often differ by orders of magnitude. This has made it difficult to use them for reliable assessments of  material quality.
