Shell-shaped active layers for omnidirectional organic photovoltaic cells
Hah, Dooyoung (SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS, 2022)For the employment of organic photovoltaic cells in wearable electronic systems, improvements in energy conversion efficiency and omnidirectionality (angular coverage) are highly appreciated. This study aims at those ... -
Symmetric Electret-Based Vibration Energy Harvesters with Curved-Beam Hinges
Hah, Dooyoung (Institute of Electrical and Electronics Engineers Inc., 2023)Broadband power spectral characteristics are desirable in vibration energy harvesters, and it can be achieved by employing curved-beam hinges, which exhibit forcedisplacement nonlinearity. Via numerical analysis by ...
