Real-World Oriented Smartphone AR Supported Learning System Based on Planetarium Contents for Seasonal Constellation Observation

open access: yesApplied Sciences, 2019
A popular astronomical concept covered by projection learning programs in the planetarium is seasonal constellation. However, a planetarium’s learning environment is limited to virtual scenes, where learners can observe seasonal constellations, but there

Anomalous Glassy Thermal Conductivity in a Perovskite Bismuthate Induced by Structural Dynamic Instability

open access: yesAdvanced Science, EarlyView.
Unraveling the underlying mechanisms at the origin of ultra‐low thermal conductivity in pristine crystals is of central relevance to designing new functional materials. Single crystals of the candidate functional material BaBiO3 show an anomalous glassy thermal conductivity, which reveals the role of strong anharmonicity and additional scattering ...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Discerning Performance Bottlenecks of State‐of‐the‐Art Narrow Bandgap Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
This work quantitatively discerns the loss mechanisms of state‐of‐the‐art low‐bandgap organic solar cells based on BTPV‐4X‐eC9 acceptors. Compared to PM6:Y6, geminate recombination of charge transfer (CT) states governs photocurrent losses. This relates to conformational freedom of these acceptors that restricts their aggregation, and also counteracts ...

The Importance of Computation in Astronomy Education [PDF]

open access: yesarXiv, 2016
Computational skills are required across all astronomy disciplines. Many students enter degree programs without sufficient skills to solve computational problems in their core classes or contribute immediately to research. We recommend advocacy for computational literacy, familiarity with fundamental software carpentry skills, and mastery of basic ...
