Enhancing the Efficiency of Perovskite Solar Cells Through Interface Engineering The quest for sustainable energy solutions has brought perovskite solar cells (PSCs) to the forefront of photovoltaic research due to their remarkable power conversion efficiencies and cost-effective fabrication processes. A critical point that significantly influences the performance of PSCs is interface engineering—the optimization of the layers between the perovskite absorber and the charge transport materials. Focusing on this aspect can lead to substantial improvements in efficiency, stability, and overall device performance. Perovskite materials have exceptional optoelectronic properties, such as high…

Solid-State Batteries: Revolutionizing Energy Storage with Enhanced Safety and Performance The shift towards sustainable energy solutions is propelling advancements in energy storage technologies. A key focus in this domain is solid-state batteries (SSBs), which are poised to outperform traditional lithium-ion batteries in terms of safety, energy density, and longevity. By replacing the liquid electrolyte with a solid one, SSBs address several limitations of current battery technology, making them a critical component in the future of electric vehicles (EVs) and renewable energy systems. Solid-state batteries utilize solid electrolytes to facilitate ion…

Reframing Sustainability through Systemic Resilience and Equity Sustainability has become one of the defining policy and ethical challenges of the 21st century. While traditionally framed in terms of environmental preservation and the reduction of ecological harm, contemporary interpretations increasingly recognize the interconnectedness of ecological, social, and economic systems. Despite this expanded understanding, many sustainability strategies remain narrowly focused, driven by carbon accounting, technological substitution, and growth-centered economics. This article contends that such reductionist approaches are insufficient for addressing the complexities of global ecological and social change. Instead, sustainability should be…

What do the city lights bring to birds? Most people in highly urbanized areas cannot see the Milky Way Galaxy duo to the existence of light pollution. The eliminated star lights could make migratory birds lose their direction, or endure with unexpected accidents. In the hidden corners shadowed by music and noise of the crowd, millions of migratory birds are killed by the highly-invisible, illuminated glass structures each year. The fact that light pollution could wash out star lights and guide the birds to somewhere else is never a new…
