Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study reports improvements in compositional homogeneity, microstructure, enhanced radiative recombination, and extended carrier lifetime of CIGS absorber via Ag incorporation. The optimal Ag‐alloyed CIGS solar cells achieve 15.5% PCE and 948 mV VOC, competing with the VOC of the Ag‐free reference sample from the same batch.

Recycling‐Induced Changes of Molecular Weight and Structural Properties in PET Monopolymer Blends

open access: yesJournal of Polymer Science, EarlyView.
The present study investigates the molecular weight, thermal, rheological, and mechanical properties of polymer blends of high and low molecular weight polyethylene terephthalate (PET) components. The research reveals that extrusion processing influences chain scission and chain extension, inhibiting the broadening of the molecular weight distribution ...

Synergy‐based crop suitability assessment for agrivoltaics: An easy‐to‐use traffic‐light framework for temperate climates

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change and the growing demand for renewable energy are putting increasing pressure on land, as food production and solar power generation often compete for the same areas. In this study, we assessed which temperate‐region crops are best suited for agrivoltaics, a technology combining farming and solar electricity production on the same land. We

The role of identification in data‐driven policy iteration: A system theoretic study

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Assessing the Performance of European Union Regions in the “People” and “Prosperity” Pillars of the SDGs

open access: yesSustainable Development, EarlyView.
ABSTRACT This paper addresses the gap in subnational assessments of Sustainable Development Goals (SDGs) by benchmarking the performance of European Union NUTS‐2 regions in the People and Prosperity pillars of the 2030 Agenda for Sustainable Development.
