Loss Analysis of Low Bandgap (Ag,Cu)(In,Ga)Se 2 Solar Cells for Tandem Applications

ABSTRACT Tandem solar cells can better harness the energy of the solar spectrum. Chalcopyrite solar cells have drawn attention, being the only highly efficient devices with a bandgap around 1.0 eV, suitable for bottom cells. In the quest for better efficiencies, we conduct a comp...

Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors

ABSTRACT Pyroelectric materials are attractive for converting heat into electricity, yet the best performance is obtained with lead‐containing ceramics, remaining a major environmental concern. Here, we address this problem by developing lead‐free barium strontium titanate multil...

The Consequences of Promoting Data Literacy among Graduate Students

Abstract We study the impact of a data literacy program on graduate students’ skills and academic outcomes at a large Italian university. The program targets students expected to have weak quantitative skills and provides 120 h of training in data interpretation and processing al...

eDNA metabarcoding provides scalable and continuous biodiversity monitoring across the tree of life

Abstract Environmental DNA (eDNA) metabarcoding has the potential to substantially expand our knowledge of global biodiversity beyond that provided by conventional approaches. However, the degree to which eDNA data provides real ecological insight, rather than primarily reflectin...

Assessment of degradation in Ion pair membrane high temperature PEM fuel cells using commercial and customized catalysts under varied operating conditions

High-temperature proton exchange membrane fuel cells (HT-PEMFCs) present considerable advantages, such as high energy efficiency and tolerance to fuel impurities; however, durability issues and catalyst costs remain major barriers to commercial adoption. This study systematically...
