About
Keisuke Tajima is a leading figure in the field of organic photovoltaics (OPVs), with a research focus on developing ultra-flexible, high-efficiency solar cells for next-generation wearable electronics and soft robotics. His major contributions center on solving the critical challenge of device stability without sacrificing performance. Tajima’s landmark 2020 paper demonstrated the creation of 3-µm-thick OPVs that achieve over 13% power conversion efficiency through a simple post-annealing process, which forms doping-induced stable interfaces. This work, cited 68 times, proved that extreme thinness and high efficiency are compatible. Building on this, his 2022 study (50 citations) tackled air stability by suppressing zinc element diffusion from electrodes, a key degradation pathway. Together, these innovations have established new benchmarks for both efficiency and environmental resilience in ultrathin OPVs. Tajima’s work is particularly notable for its practical impact: by enabling devices that are not only highly efficient but also robust enough for real-world deployment, he is paving the way for self-powered wearable sensors and medical implants. His research continues to push the boundaries of organic electronics, making him a pivotal figure in sustainable energy technology.
