· Module reliability and durability
· System-level optimisation of PV systems
· Perovskite stability
· Next-generation silicon solar cell technologies
· Emerging PV materials (e.g., organic, dye-sensitized, quantum dot)
· Tandem solar cell designs
· Optical enhancement strategies
· Scalable and sustainable manufacturing processes
· Degradation analysis and failure mechanisms
· Sustainability and recycling of PV materials and modules
· Field performance evaluation and long-term testing
· Grid integration of large-scale PV power
· Hybrid systems (e.g., PV-wind, PV-hydro)
· Energy storage solutions for PV applications
· Intelligent control and management of PV systems
· Solar power and load forecasting
· Metaheuristic optimisation for PV system design and operation
