Robust crystalline silicon photovoltaic module (c-Si PVM) for the tropical climate: future facing the technology
摘要： A critical impediment to the adoption and sustained deployment of crystalline silicon photovoltaic modules (c-Si PVMs) in the tropical climate is the accelerated degradation of their interconnections. At 40.7% c-Si PVM interconnect failure rate worldwide and significantly higher in the tropics. A review of impact of elevated ambient temperature operations on accelerated interconnection degradation is critical to achieving the system’s sustainability and reliability up to the 25-year design lifespan. This study reviews critical module’s operational parameters to advise on the future facing creation of robust module for the tropical region. Key areas reviewed include manufacturing process, solar cell efficiency, interconnection technology and R&D parameters. The review discusses the state-of-the-art in c-Si PVM interconnection technologies and propose back-junction-back-contact (BJ-BC) cell technology for adoption in the manufacture of the next generation of robust c-Si PVM for the tropics. The review findings provide insight into the future facing the robust c-Si PVM technology that is useful to the module design engineers.

All-Waste Hybrid Composites with Waste Silicon Photovoltaic Module
摘要： Nowadays, global warming, energy issues and environmental concern have forced energy production stakeholders to find new low carbon solutions. Photovoltaic technologies as renewable energy resources represent a competitive way for the transition from conventional fossil fuels towards a renewable energy economy. The highest renewable energy systems (RES) market share is based on silicon photovoltaic (Si-PV). The installed RES have rapidly increased over the last two decades, but, after the end of their service life, they will be disposed of. Therefore, the constant increase of the installed RES has attracted the global concern due to their impact on the environment and, most of all, due to the content of their valuable resources. However, the rational management of RES waste has not been addressed so far. The paper represents an extension of a previous work focused on Si-PV recycling by developing all waste hybrid composites. The extension research conducted in this paper is related to the influence of Si-PV characteristics on the mechanical performances and water stability of the hybrid composites. All waste hybrid composites developed by embedding different Si-PV grain sizes were tested before and after water immersion in terms of mechanical strength, interfacial adhesion, crystallinity and morphology by scanning electron microscopy (SEM) analyses. The results revealed the better performance of such Si-PV composites compared to that of sieved composites even after long term water immersion. Therefore, high-content Si-PV hybrid composites could be developed without Si-PV powder sieving. Further on, all waste hybrid composites could be used as paving slabs, protective barriers for outdoor applications.
