In a significant advancement for portable energy solutions, researchers from Donghua University have unveiled a groundbreaking thin and lightweight solar photovoltaic/thermal (PV/T) collector designed to meet the growing energy demands of outdoor activities and survival situations. This innovative technology addresses the limitations of traditional energy sources, which often necessitate cumbersome fuel supplies and heavy equipment.
The study, led by CHEN Yixin from the College of Environmental Science and Engineering, explores the integration of a Cu(In,Ga)Se2 (CIGS) thin film battery with a capillary network system. This combination not only enhances energy collection but also optimizes the efficiency of both electrical and thermal energy conversion. “Our module demonstrates a remarkable balance of high power density and portability,” CHEN stated, highlighting the potential applications for outdoor enthusiasts and professionals in remote locations.
Under typical climate conditions in Shanghai, the research team achieved an impressive all-day electrical efficiency of 13.04% and thermal efficiency of 22.50%. The experimental results revealed that the optimal water flow rate of 2.1 L/min not only maximized energy collection but also effectively cooled the solar cells, reducing their temperature by 10 degrees Celsius and increasing overall energy utilization efficiency by nearly 24%. This is a game-changer for energy supply in outdoor settings, where traditional solar panels may fall short due to their rigidity and weight.
The implications of this research extend beyond mere convenience; they could reshape the commercial landscape of energy solutions. As the demand for portable energy sources rises, particularly in sectors like outdoor recreation, military operations, and emergency services, this lightweight PV/T collector presents a viable alternative to conventional generators. Its flexibility and efficiency could encourage wider adoption of solar technology in diverse fields, ultimately contributing to a more sustainable energy future.
The findings of this study were published in the journal ‘发电技术’, which translates to ‘Power Generation Technology’. As the energy sector continues to evolve, innovations like those presented by CHEN and his team could pave the way for new designs in outdoor energy equipment, making renewable energy more accessible and practical for users in various environments.
