Two perovskite books published with a chapter on hysteresis and solar-cell physics by us

The new Wiley books "Hybrid Perovskite Solar Cells: Characteristics and Operation" edited by Hiroyuki Fujiwara and "Perovskite Photovoltaics and Optoelectronics" edited by Tsutomu Miyasaka are available.

Our chapter "Hysteresis in J–V Characteristics" provides a guide on how to interpret and analyze current-voltage curves of solar cells. It provides the toolbox needed to investigate the reasons behind performance-limiting processes with focus on the hysteresis in the J-V curve.

Our chapter "Physics of Perovskite Solar Cells: Efficiency, Open-Circuit Voltage, and Recombination" gives an illustrative introduction into the physics of solar cells without going into too much detail. The chapter accounts for applied aspects of perovskite solar cells (PSCs) and addresses students and researchers of various backgrounds. The focus is on how to characterize and interpret efficiency-limiting processes correctly. It advocates for a careful deployment of established characterization methods whose common interpretations might not be readily applicable to PSCs, probable reasons being the thin-film solar cell architecture with a highly emissive absorber or peculiar properties of the perovskite as a mixed ionic–electronic conductor...
