The magic of physics: Science to marvel at

Rise and Decay of the Photovoltage

Distinguishing between recombination and charge extraction is a challenge for solar cell characterization. Using the rise and decay of the transient photovoltage after a laser pulse can be a solution for the problem.

Characterizing Energetic Disorder in Organic Solar Cells

Energetic disorder reduces solar cell efficiencies but is difficult to characterize. Hartnagel et al. perform a comparative study of different methods to quantify disorder and show how method-specific bias in the resulting values can modify the results.

Do Diffusion Lengths Really Matter for Perovskite Solar Cells?

The diffusion length is frequently used to explain poor charge collection in halide perovskite solar cells. However, in the presence of only moderately conductive charge transport layers, non-linear series resistances can modulate the carrier density and thereby the recombination losses even if transport in the perovskite itself is nearly perfect.

Interpretation of time constants from frequency domain measurements of perovskite solar cells

Ravishankar et al. developed a model to describe the frequency domain response of perovskite solar cells with an emphasis on the role of transport layers. Application to experimental data identifies that measured time constants are limited by charge carrier extraction rather than by recombination.
