Comment on "Resolving spatial and energetic distributions of trap states in metal halide perovskite solar cells"
Sandheep Ravishankar, Thomas Unold, Thomas Kirchartz
Ni et al. report minimum bulk trap densities of 10^11 cm-3 and 1-4 orders change in interfacial trap densities derived from drive-level capacitance profiling of lead halide perovsk…
Water adsorption enhances electrical conductivity in transparent p-type CuI
Andrea Crovetto, Hannes Hempel, Marin Rusu +4
CuI has been recently rediscovered as a p-type transparent conductor with a high figure of merit. Even though many metal iodides are hygroscopic, the effect of moisture on the elec…
Upper limit to the photovoltaic efficiency of imperfect crystals
Sunghyun Kim, José A. Márquez, Thomas Unold +1
The Shockley-Queisser (SQ) limit provides a convenient metric for predicting light-to-electricity conversion efficiency of a solar cell based on the band gap of the light-absorbing…
Pathways towards 30% efficient single-junction perovskite solar cells and the role of mobile ions
Jonas Diekmann, Pietro Caprioglio, Moritz H. Futscher +13
Perovskite semiconductors have demonstrated outstanding external luminescence quantum yields, enabling high power conversion efficiencies (PCE). However, the precise conditions to…
High Open Circuit Voltages in pin-Type Perovskite Solar Cells through Strontium Addition
Pietro Caprioglio, Fengshuo Zu, Christian M. Wolff +7
The incorporation of even small amounts of strontium (Sr) into lead-based quadruple cation hybrid perovskite solar cells results in a systematic increase of the open circuit voltag…
The perovskite/transport layer interfaces dominate non-radiative recombination in efficient perovskite solar cells
Martin Stolterfoht, Pietro Caprioglio, Christian M. Wolff +12
Charge transport layers (CTLs) are key components of diffusion controlled perovskite solar cells, however, they can induce additional non-radiative recombination pathways which lim…
