Predicting the Electrical Behavior of Colored Photovoltaic Modules Integrating Absorptive or Diffusive Layers or PMMA Films Doped with Organic Chromophores

Abstract

The advancement of photovoltaic (PV) technology is critical for sustainable energy production, with silicon-based solar cells being the most prevalent due to their efficiency and cost-effectiveness. In recent years, the use of materials to change the color of conventional silicon-based PV cells, materials that can be laminated or not during the construction of the PV module, has become widespread. Colored PV cells offer aesthetic versatility, making them suitable for integrated architectural applications. However, these materials affect the performance of the final product. This study focuses on developing a predictive model for the performance of colored silicon PV cells. A comprehensive approach combining experimental data and computational simulations is employed to understand the impact of various colors on the electrical performance of colored PV modules, based on the optical properties of the colored layers. The model demonstrates high accuracy across a range of coloring technologies, including selective absorbers, diffusive layers, and fluorescent materials. The developed model accurately predicts the performance metrics of colored PV cells, providing valuable insights for optimizing design and material selection.
