Binqing Wei: Boost the Power Conversion Efficiency of Single-Junction Silicon Solar Cells

Binqing Wei (University of Delaware): Boost the Power Conversion Efficiency of Single-Junction Silicon Solar Cells through Temperature-Regulating Invited talk at the TACO PhD Meeting 2025 Abstract: Solar cells are pivotal in addressing some of the most pressing challenges facing our planet today. As a clean and renewable energy source, solar cells convert sunlight into electricity, offering a sustainable and environmentally friendly alternative to conventional energy sources, significantly reducing our dependence on fossil fuels, mitigating climate change, and curbing environmental degradation. The widespread adoption of solar technology promises to achieve energy independence for nations, reduce greenhouse gas emissions, and promote a more sustainable and resilient energy infrastructure. Additionally, solar power can potentially empower communities in remote or off-grid areas, providing access to electricity where traditional power sources may be impractical or unavailable. The importance of solar cells lies not only in their capacity to generate clean energy but also in their role as catalysts for a more sustainable and equitable future. Enhancing the power conversion efficiency (PCE) of solar cells is a constant and essential endeavor to advance the utilization of renewable electricity and build sustainable technology and society. However, the primary factor hindering PCE is the energy loss in the form of heat dissipation, imposing a PCE limitation of less than 33% for single-junction Si solar cells, the most popular solar conversion technology thus far. Improving the PCE further to the next level is a fundamental and practical challenge. In this talk, I will discuss the possibilities of boosting the PCE of Si solar cells to over the S-Q limitation from temperature regulation, light penetration, and carriers’ density and mobility perspectives.
