Template Language for DSI Databases

Débora Raposo, Davide Faggionato, Barbara Ebert, Pablo Orozco et autres

To support the requirements for databases that provide access to Digital Sequence Information (DSI), agreed to by consensus of the Parties to the Convention on Biological Diversity (CBD)[1] listed in decision 16/2, an international scientific working group developed the following “template language”. …

Process Parameter Specification and Control in Solution Processing of Hybrid Perovskite Photovoltaics: From Domain‐Specific Jargon to Evidence‐Based, Unambiguous Description of Experimental Workflows

Simon Ternes, Christoph J. Brabec, Luigi Angelo Castriotta, Thomas Exlager et autres

Abstract Within the last 20 years, hybrid perovskite solar cells (PSCs) have reached remarkable power conversion efficiencies. Further, scalability of hybrid perovskite deposition routines and stability of PSCs have been significantly improved. Yet, a critical roadblock remains: Poor reproducibility largely caused by …

Deep Learning-Assisted Multivariate Analysis for Nanoscale Characterization of Heterogeneous Beam-Sensitive Materials

Felix Utama Kosasih, Fanzhi Su, Tian Du, Sinclair R. Ratnasingham et autres

Nanoscale materials characterization often uses highly energetic probes which can rapidly damage beam-sensitive materials, such as hybrid organic-inorganic compounds. Reducing the probe dose minimizes the damage, but often at the cost of lower signal-to-noise ratio (SNR) in the acquired data. This work …

Overcoming Nanoscale Inhomogeneities in Thin-Film Perovskites via Exceptional Post-annealing Grain Growth for Enhanced Photodetection

Tian Du, Filipe Richheimer, Kyle Frohna, Nicola Gasparini et autres

High Resolution Image Download MS PowerPoint Slide Antisolvent-assisted spin coating has been widely used for fabricating metal halide perovskite films with smooth and compact morphology. However, localized nanoscale inhomogeneities exist in these films owing to rapid crystallization, undermining their overall optoelectronic performance. …

Optimal Interfacial Band Bending Achieved by Fine Energy Level Tuning in Mixed-Halide Perovskite Solar Cells

Mátyás Dabóczi, Sinclair R. Ratnasingham, Lokeshwari Mohan, Chenfeng Pu et autres

Most highly efficient perovskite solar cells employ mixed iodide–bromide photoactive layers; however, understanding the beneficial effect of the low (5–15 mol %) bromide content is incomplete. Here, a series of MAPb(I 1– x Br x ) 3 perovskite layers are investigated to …

Determining Out-of-Plane Hole Mobility in CuSCN via the Time-of-Flight Technique To Elucidate Its Function in Perovskite Solar Cells

Lokeshwari Mohan, Sinclair R. Ratnasingham, Julianna Panidi, Mátyás Dabóczi et autres

Copper(I) thiocyanate (CuSCN) is a stable, low-cost, solution-processable p-type inorganic semiconductor used in numerous optoelectronic applications. Here, for the first time, we employ the time-of-flight (ToF) technique to measure the out-of-plane hole mobility of CuSCN films, enabled by the deposition of 4 …
