Description

Miniaturization and integration has become the trend of future electronic device and attracted much attention in several research fields ranging from nanoelectronics to biophysics.[1-4] A variety of microelectronic devices, including micro capacitor, micro sensor, micro LED, has been fabricated.[2,4,5] To achieve an ideal self-powered microelectronic system, the miniaturization of energy harvester is also required. The miniaturization of solar cell has been regarded as a promising approach to match the requirements of micro autonomous devices. In the past decade, several novel geometries of solar cell has been reported spanning across millimeter scale to nanoscale.[6-8] However, it is still quite challenging to achieve a three-dimensional (3D) micro solar cell, which can take advantages of wide-angle response and integratability compared with planar thin-film solar cells. Based on the strain engineering of nanomembranes, rolled-up nanotechnology offers great opportunities to build up micro- and nanoscale 3D devices.[9,10] In this talk, I will demonstrate the first realization of a rolled-up 3D micro organic solar cell. Transparent self-assembled strain bilayer was utilized for rolling the planar micro organic solar cell into the tubular structure. Fabrication process has been carefully explored. A measurement stage for characterizing micro solar cell has been built up. Preliminary device performances of the planar and the rolled-up have been obtained and discussed. The resulting 3D micro organic solar cell offers a potential way of harvesting solar energy in wide angle to power micro robot systems such as robotic bees.[11]
