“…While CPV-T systems have demonstrated high overall efficiencies, their cost is still significantly higher than flat-plate alternatives. This can be explained by the increased complexity (e.g., tracking [14] secondary optics [15], etc.) and higher cost of the often used CPV multi-junction cells [16,17].…”

Concentrator photovoltaics (CPVs) have demonstrated high electrical efficiencies and technological potential, especially when deployed in CPV–thermal (CPV-T) hybrid absorbers, in which the cells’ waste heat can be used to power industrial processes. However, the high cost of tracking systems and the predominant use of expensive multi-junction PV cells have caused the market of solar co-generation technologies to stall. This paper describes the development and testing of a low-cost alternative CPV cell based on crystalline silicone (c-Si) for use in a novel injection-molded parabolic hybrid solar collector, generating both, photovoltaic electricity and thermal power. The study covers two different c-Si cell technologies, namely, passive emitter rear contact (PERC) and aluminum back surface field (Al-BSF). Simulation design and manufacturing are described with special attention to fingerprinting in order to achieve high current carrying capacities for concentrated sunlight. It was determined that Al-BSF cells offer higher efficiencies than PERC for the considered use case. Solar simulator tests showed that the highly doped 4 cm2 cells (50 ohm/sq) reach efficiencies of 16.9% under 1 sun and 13.1% under 60 suns at 25 °C with a temperature coefficient of −0.069%(Abs)/K. Finally, options to further improve the cells are discussed and an outlook is given for deployment in a field-testing prototype.

Rural farms constitute a vital component of a country’s agricultural landscape, traditionally reliant on energy installations known for their reliability yet notorious for their energy-intensive and inefficient characteristics. While the smart farm concept, integrating renewable energy sources and resource management technologies, has seen widespread adoption in domestic and industrial sectors, rural farms have been slower to embrace these innovations. This study presents a groundbreaking solution, deployed on a rural farm in Portugal, resulting in an impressive 83.24% reduction in energy consumption sourced from the grid. Notably, this achievement translates to a substantial reduction in CO2 emissions, aligning with the growing need for environmentally sustainable farming practices. The technical intricacies of this pioneering solution are comprehensively described and juxtaposed with other scientific case studies, offering valuable insights for replication. This initiative represents a vital first step towards the integration or combination of conventional farming with photovoltaic energy production, exemplified by agrivoltaic systems. In conclusion, this research showcases the potential for rural farms to significantly enhance energy efficiency and financial viability, thereby contributing to a more sustainable and cost-effective agricultural sector. These findings serve as a model for similar endeavors, paving the way for a greener and more economically viable future for rural farming practices.

Advances in the design of future solar-photovoltaic power systems should address performance constraints while maintaining a high-power output. An identified constraint is that of high tracker acquisition costs for large number of solar panels deployed in solar farms. The cost and overheads associated with solar tracker acquisition for the case of large-scale power farms should be addressed in future solar farms. This paper addresses this challenge and proposes the incorporation of the bio-inspired orientation diversity approach in future solar panel systems. In the proposed design approach, the future solar panel is realized from a solar tree that hosts multiple mini-solar panels. The mini solar panels are hosted at varying levels of deployment altitudes and orientation. The performance evaluation is carried out by scenario description and simulation in MATLAB. Performance evaluation results obtained show that the proposed mechanism enhances the power output and reduces tracker acquisition costs by an average of 35.6 %, and 65%, respectively.
