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

Advanced Energy Materials, Volume 16, Issue 3, 21 January 2026.
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

Quantum GraviElectro Dynamics

Annalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Semantic primitives and compositionality: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, Volume 77, Issue 1, Page 198-223, January 2026.
Abstract The term semantic primitives refers to a set of basic, atomic concepts from which all other (compound) concepts are constructed. It presupposes the principle of compositionality—the idea that complex items or expressions can be formed by combining simpler constituents.

Simple Fabrication Method of Needle‐Type Carbon‐Disk Microelectrodes Using Conductive Thermoplastics

ChemElectroChem, Volume 13, Issue 1, January 2026.
A quick and simple method for fabricating needle‐type carbon microelectrodes is presented, using low melting point, electrically conductive, thermoplastics and the heat of a candle. The resulting partially blocked electrode surface is reasoned using numerical simulations and experiments.
