This semester, I had the opportunity to participate in the “35th International Photovoltaic Science and Engineering Conference (PVSEC-35),” held in Numazu from November 10th to 15th. The conference brought together experts from academia and industry to discuss various topics in photovoltaic research and development, including photovoltaic systems for sustainable energy, wafer-based silicon photovoltaics, thin-film photovoltaic modules, and cutting-edge perovskite technology.
I was honored to present my research through a poster session focused on deploying photovoltaics from a techno-socioeconomic perspective. This opportunity allowed me to share my work and helped me confidently communicate my ideas to an expert audience. On my first day, I attended tutorial sessions led by field experts to gain insights into reliability issues and prospects of photovoltaic modules, such as improved module durability and extended long lifetimes. Discussions also highlighted the development of guidelines for advanced PV technologies, including agrivoltaics and floating systems, which address diverse environmental challenges and enhance system resilience.
While my background in electrical engineering helped me navigate most topics, I found certain areas, like perovskite tandem solar cells, were quite complex. Perovskite is emerging as a new material for next-generation solar cells, owing to its lightweight, flexible nature and high conversion efficiency. Furthermore, its cost-effectiveness makes it an attractive option for future solar cell development, as only minimal material is required for production.
What fascinated me most was the discussion about the future trends in photovoltaics. Rather than just the new technologies to enhance efficiency and reduce costs, there is growing awareness of the environmental impacts of PV systems, particularly concerning waste management. For example, Japan anticipates a substantial increase in solar panel waste, more than 170,00 tons, by 2030, highlighting the urgent need for better recycling technologies to handle end-of-life PV modules sustainably.
Finally, I am thrilled to share that I was awarded the poster award at this PVSEC-35 conference. This recognition is a testament to my research’s significance and a major milestone in achieving my academic and professional goals. The experience at PVSEC-35 was both enlightening and inspiring, enhancing my understanding of photovoltaic technologies and connecting me with leading experts. Moreover, I am grateful to the Japan International Cooperation Agency (JICA) for their support, which made my participation in this conference possible.
