Effect of doping, photodoping and bandgap variation on the performance of perovskite solar cells
Basita Das, Irene Aguilera, Uwe Rau +1
Most traditional semiconductor materials are based on the control of doping densities to create junctions and thereby functional and efficient electronic and optoelectronic devices…
Multilayer Capacitances: How Selective Contacts Affect Capacitance Measurements of Perovskite Solar Cells
Sandheep Ravishankar, Zhifa Liu, Uwe Rau +1
Capacitance measurements as a function of voltage, frequency and temperature are useful tools to identify fundamental parameters that affect solar cell operation. Techniques such a…
Understanding Transient Photoluminescence in Halide Perovskite Layer Stacks and Solar Cells
Lisa Krückemeier, Benedikt Krogmeier, Zhifa Liu +2
While transient photoluminescence measurements are a very popular tool to monitor the charge-carrier dynamics in the field of halide perovskite photovoltaics, interpretation of dat…
Interface Optimization via Fullerene Blends Enables Open-Circuit Voltages of 1.35 V in CH3NH3Pb(I0.8Br0.2)3 Solar Cells
Zhifa Liu, Johanna Siekmann, Benjamin Klingebiel +2
Non-radiative recombination processes are the biggest hindrance to approaching the radiative limit of the open-circuit voltage for wide-band gap perovskite solar cells. In addition…
