A Test of Electroluminescent Panels for a Helicopter Emergency Escape Lighting System [PDF]

, 1984
Abstract : The effectiveness of a lighting system composed of electroluminescent panels and proposed for use in illuminating escape hatches was tested. It was visible to light-adapted subjects in turbid water at the distance and viewing angles required by the Naval Air Development Center.

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Degradation analysis of 5-year field exposed photovoltaic modules using low-cost thermography, electroluminescence and I-V curve tests in Ecuador [PDF]

2020 International Conference on Smart Energy Systems and Technologies (SEST), 2020
Detection of degradation of photovoltaic (PV) modules is important for the maintenance and operation of solar PV farms to reduce production losses. Infrarred (IR) Thermography, Electroluminescence (EL) and I-V curve tracers are detection techniques that generally use high-cost equipment, which limits their use in developing countries due to the tight ...
