In a landmark announcement reverberating across the global scientific community, the National Institute for Materials Science (NIMS) has revealed the recipients of the prestigious NIMS Award for 2025. This year’s award poignantly highlights breakthrough advances in environmental and energy materials, focusing specifically on revolutionary strides made in perovskite solar cell technology. The trio of awardees, Prof. Tsutomu Miyasaka of Toin University of Yokohama, Prof. Henry J. Snaith of the University of Oxford, and Prof. Nam-Gyu Park of Sungkyunkwan University, are being celebrated for their pioneering work that has fundamentally reshaped the landscape of renewable energy research and practical application.
Perovskite solar cells have rapidly climbed to the forefront of photovoltaic research over the past decade due to their remarkable potential for high efficiency and low-cost manufacturing. Despite their promise, these cells historically struggled with issues pertaining to operational stability and longevity, hindering widescale commercialization. The NIMS Award-winning research directly addresses these bottlenecks by introducing a crucial innovation—the solid-state hole transport layer. This component has significantly enhanced both the stability and photoelectric conversion efficiency of perovskite solar cells, marking a transformative step toward their real-world viability.
The integration of the solid-state hole transport layer represents more than a mere incremental improvement; it is a quantum leap in device architecture. By replacing traditional liquid electrolytes, which were prone to degradation and leakage issues, with a solid material layer, the perovskite solar cells now exhibit increased durability under environmental stresses such as moisture and heat. Moreover, this innovation facilitates better charge extraction and transport within the cell, reducing energy losses that previously limited device efficiency.

Technically, the hole transport layer functions by selectively transporting positive charge carriers (holes) from the perovskite absorber to the electrode, ensuring minimal recombination losses while maintaining electrical insulation from the electron-collecting layer. This selective transport is vital because any inefficiency at this interface reduces the overall photocurrent and, subsequently, the power conversion efficiency of the solar cell. The awardees’ contributions effectively stabilized this interface, mitigating hysteresis effects and boosting long-term operational stability—key parameters for real-world application.
What makes this collaborative breakthrough exceptionally noteworthy is its global scale of impact. The independent but synergistic efforts of Miyasaka, Snaith, and Park not only pioneered the application of solid-state hole transport materials but also laid the experimental and theoretical foundations that many research groups worldwide have built upon. Their work bridged the gap between laboratory-scale high efficiencies and scalable, durable devices poised for commercialization.
Beyond the scientific rigor, this achievement aligns seamlessly with the broader imperative of creating sustainable energy technologies. Perovskite solar cells offer a pathway toward affordable, lightweight, and flexible photovoltaics that can be deployed in diverse environments—ranging from urban rooftops to portable electronics. The improved stability fosters confidence among investors and manufacturers, potentially catalyzing mass production models that could accelerate the global transition to clean energy sources.
The NIMS Award ceremony and associated symposium will convene at the Tsukuba International Congress Center on November 11th, 2025. This gathering promises a platform not only for celebrating these remarkable scientific accomplishments but also for fostering dialogue among materials scientists, photovoltaic engineers, and policy makers. The symposium will include detailed lectures given by the awardees themselves, invited talks from leading researchers, and presentations that highlight complementary advancements within the field of energy-related materials.
The international stature of the NIMS Award reflects its stringent selection process, which evaluates groundbreaking contributions from four major subdivisions of materials science: environmental and energy materials, functional materials, structural materials, and basic materials science. Its thematic approach each year ensures that impactful research with real-world applications is prioritized, further emphasizing the role of materials science in addressing pressing technological and societal challenges. For 2025, the spotlight on energy materials underscores the urgent global necessity to innovate sustainable energy technologies.
The recognition of perovskite solar cell innovation by a leading institution like NIMS also highlights the importance of cross-border scientific collaboration. The honorees hail from prominent institutions in Japan, the United Kingdom, and South Korea respectively, underscoring the collaborative nature of contemporary materials science research. Their combined efforts exemplify how diverse academic cultures and expertise can converge to solve some of the most daunting technological problems.
Looking forward, the developments recognized by the NIMS Award will likely stimulate further research into alternative materials and device architectures that enhance photovoltaic performance. This includes exploring new solid-state hole transport materials with better electronic properties, improving perovskite crystallinity and interface engineering, and integrating these cells into tandem configurations for surpassing traditional silicon-based solar cell efficiency limits.
Moreover, from an industrial perspective, the stabilization of perovskite solar cells opens the door for their incorporation into building-integrated photovoltaics (BIPV), wearable electronics, and even aerospace applications, where weight and flexibility are paramount. These applications have the potential to revolutionize how solar energy is harvested and utilized, moving beyond the constraints of traditional rigid panels.
The NIMS Award 2025 thus not only celebrates an exceptional scientific breakthrough but also symbolizes a critical inflection point in the journey toward sustainable energy futures. It honors the dedication and ingenuity of researchers who have translated fundamental materials science insights into transformative technologies. Their work foreshadows a future where clean, efficient, and affordable solar energy is universally accessible, contributing meaningfully to reducing global carbon emissions and combating climate change.
As the world watches the upcoming award symposium, anticipation builds regarding the new research directions and collaborations that this recognition might inspire. The dissemination of knowledge through such prestigious events helps cultivate a vibrant scientific community and accelerates the translation of innovative materials research into solutions that tackle humanity’s greatest challenges.
In summary, the 2025 NIMS Award highlights essential advancements in perovskite solar cell technology, emphasizing the integration of the solid-state hole transport layer. This advancement addresses longstanding issues of stability and efficiency, enabling practical application potentials for perovskite photovoltaics. By honoring Prof. Miyasaka, Prof. Snaith, and Prof. Park, NIMS acknowledges not only their individual excellence but also the enduring global impact of their collaborative scientific achievements.
