Enhancing the Efficiency and Sustainability of Solar Cells
As climate change caused by greenhouse gas emissions, especially CO2 from electricity and heat production, has become a major threat to global warming and ecosystems, solar cells provide a direct way to convert sunlight into electricity without producing carbon emissions during operation. Because of this, solar energy plays a vital role in reducing greenhouse gas emissions.
In this thesis, strategies to enhance the performance and durability of solar cells are explored, focusing on materials engineering, device architecture, and printing-based fabrication techniques. Particular emphasis is placed on interface engineering at the micro- and nanoscale to improve electron transfer between components and minimize current losses. These interface modifications enhance charge transport and reduce device performance degradation, leading to more efficient and stable solar cells.
Overall, this work shows that interface engineering is a powerful method for advancing high-performance, sustainable next-generation solar cell technologies.
