What is a Charge Carrier Lifetime in a Perovskite Solar Cell?

Lifetimes of charge carriers are a key metric to quantify recombination in solar cells. However, due to different measurement modes, the word “lifetime” might mean many different things thereby making quantitative comparisons impossible. Here a consistent model for transient spectroscopy analysis is shown to solve this problem.

Quantifying Efficiency Limitations in All-Inorganic Halide Perovskite Solar Cells

All-inorganic perovskites, which replace the organic A-site cation with inorganic elements, are promising candidates for photovoltaics due to their improved stability relative to hybrid perovskites. Here Yuan et al. review the state-of-the-art of all-inorganic perovskites for photovoltaic applications by performing detailed meta-analyses of key performance parameters on the cell and material level.

Quantifying Recombination Losses for Perovskite Solar Cells

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.

Organic Solar Cells for Indoor Applications

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.
