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.

Strategy for simple, on-site failure analysis: investigating bubbles and burn marks in backsheets of PV modules

EPJ Photovoltaics
We present a practical, field-deployable workflow for the identification and analysis of localized polymer degradation in photovoltaic modules, observed as bubbles and burn marks in three multi-MWp power plants in Brazil and Germany.

To Greater Twist: A Kinetically Biased π‐Radical Cascade

Angewandte Chemie International Edition, EarlyView.
π‐Radical cascades enable step‐economic construction of complex polycyclic aromatic frameworks. In this work, we show that a multifurcating pathway can be kinetically steered toward a single, more distorted product. This counterintuitive “falling‐upward” outcome arises from an intrinsic mechanistic bias, revealing a broader dimension of control in π ...

Dealing with Shadows When Modelling BIPV Façades with Conventional PV Tools

Buildings
Building-Integrated Photovoltaics (BIPV) can contribute to decarbonisation, but its large-scale deployment requires accurate energy yield predictions that justify these systems during the decision-making process to ensure cost-effectiveness.
