Capacitance measurements are commonly used to estimate defect densities in a solar cell. Ravishankar et al. show that for a solar cell comprising of multiple layers, the traditional analysis of capacitance data is erroneous because the capacitance response of the absorber layer is hidden by overlapping responses from the other layers.

Recombination is one of the major loss processes in any solar cell. Solar cell optimiation therefore relies on characterization techniques to quantify recombination. Here a new approach is proposed based on voltage dependent photoluminescence.

Comparing efficiencies of solar cells for indoor applications is challenging due to the variety of light sources and lack of standards. Lübke et al. show a solution to this problem that allows comparison of data measured with a variety of different light sources.
