Advanced Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 24, 2025

Abstract Post‐Li battery technologies are becoming increasingly important. The diverse range of electrically powered devices requires a diversification electrochemical energy storage technologies. Organic electrode materials particular importance for alternative batteries, not only because the natural abundance their constituting elements and low toxicity, but also operating principle redox reactions compatibility with many types chemistries, including multivalent metal anionic batteries. All‐organic batteries still “young” field research offer promising opportunities in terms mechanical processing properties. In development using organic understanding mechanisms, different cell correct interpretation data is utmost importance. This comprehensive review offers insight into working organic‐based material design considerations, structure‐property relations, highlighting standardized terminology, characterization newly developed cells, distinguishing between half‐cells full‐cells.

Subcell‐Resolved EQE Method Using Reverse Voltage Biasing for Multijunction Photovoltaics With Overlapping Subcell Absorptance

Progress in Photovoltaics Research and Applications, Год журнала: 2025, Номер unknown

Опубликована: Апрель 21, 2025

ABSTRACT External quantum efficiency (EQE) measurements of individual subcells in multijunction photovoltaic devices are essential to evaluate current matching and iterate the design process. The standard light biasing technique used measure subcell EQE falls short when multiple absorb within same spectral region. In this work, we demonstrate a three‐step reverse voltage method, which measures any number with overlapping absorptance: (1) A bias is applied generate mismatch between subcells. (2) Current–voltage ( I–V ) characteristics measured into bias, where limiting enters reverse‐bias breakdown device climbs plateau at photocurrent next subcell, producing staircase curve. (3) Each curve using its plateau. We approach for two‐junction GaAs‐based photonic power converter, comparing method revealing better than 0.8% absolute agreement top junction preferentially biased method. viability by measuring all six‐junction converter.
