Integrating Emerging Photovoltaic Technologies, Smart Energy Networks, and Sustainable Investment Strategies for Global Energy Transition

The rising demand for clean and sustainable energy has increased global awareness in renewable energy technologies (RETs) as an answer to energy insecurity, climate change and environmental degradation. This paper examines the position of next-generation smart energy networks, solar energy systems and sustainable investment approaches in enabling global energy transition. The study employs a review-based method by analyzing modern improvements in RETs, distributed energy systems, and emerging photovoltaic (PV) inventions. Particular consideration is given to innovative solar technologies, including quantum dot solar cells, perovskite solar cells, solar textiles, organic photovoltaics, solar skin, solar glass and solar films. The review demonstrates that these emerging technologies offer substantial advantages such as better flexibility, lower production costs, lightweight designs and broader application prospects compared with conventional silicon-based solar cells. The study also highlights the growing importance of distributed energy resources (DER), microgrids, smart grids, and energy storage structures in improving energy access, reliability and sustainability. Though, challenges such as soaring investment costs, technological ambiguity, durability concerns and commercialization barriers reduce large-scale utilization. The paper concludes that attaining a sustainable energy future needs the addition of ground breaking solar technologies, intelligent energy management systems and efficient investment approaches. Solidification of research, helpful policies and financial investment will quicken renewable energy implementation, lessen carbon emissions and support global sustainable development goals.
