Special Issue Information

Dear Colleagues,

As the demand for solar photovoltaic (PV) energy continues to increase, the performance of PV cells/modules/systems has become an important part of the PV industry. The efficiency of solar cells and PV modules has significantly improved over the past few decades. However, there is still room for further improvement in the PV energy output performance, especially in PV modules consisting of various PV module components, such as encapsulants, backsheets, glass, etc. This Special Issue aims to gather the latest research and developments in this field and to bring together leading experts to share their findings.

Topics of interest for publication include, but are not limited to:

  • Performance optimization of photovoltaic modules and/or systems.
  • Novel PV module materials and manufacturing techniques.
  • PV module reliability, durability, and degradation analysis.
  • Advanced design and modelling of photovoltaic modules.
  • Advanced characterization and testing methods for photovoltaic modules.

Efficiency losses resulting from electrical mismatching in densely packed photovoltaic arrays present a significant challenge, particularly exacerbated in nonuniformly illuminated receivers and under varying temperatures. Serial configurations are particularly susceptible to radiation nonuniformities, while parallel systems are negatively affected by temperature variations. Various authors have recommended the incorporation of electrical voltage and current sources to mitigate these losses. This study explores different electrical connection configurations utilizing concentrated photovoltaic (CPV) cells and DC-DC electrical current converters. A self-adaptive microfluidic cell matrix cooling system is employed to mitigate thermal dispersion caused by the highly nonuniform illumination profile. The obtained results for each configuration are compared with the total electrical power produced by individual cells, operating under identical radiation and temperature conditions to those of the entire array. The results reveal a noteworthy increase in production across all studied configurations, with the parallel–series arrangement demonstrating the most promising practical utility. This configuration exhibited a remarkable 50.75% increase in power production compared with the standard series connection. Full article
