Analytical Modelling of High Concentrator Photovoltaic Modules Based on Atmospheric Parameters

International Journal of Photoenergy, Volume 2015, Issue 1, 2015., 2015
The goal of this paper is to introduce a model to predict the maximum power of a high concentrator photovoltaic module. The model is based on simple mathematical expressions and atmospheric parameters. The maximum power of a HCPV module is estimated as a function of direct normal irradiance, cell temperature, and two spectral corrections based on air ...

RMS Current of a Photovoltaic Generator in Grid‐Connected PV Systems: Definition and Application

International Journal of Photoenergy, Volume 2008, Issue 1, 2008., 2008
This paper includes a definition of a new and original concept in the photovoltaic field, RMS current of a photovoltaic generator for grid‐connected systems. The RMS current is very useful for calculating energy losses in cables used in a PV generator. As well, a current factor has been defined in order to simplify RMS current calculation.

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

Advanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential
