Self-Assembly of Micro-Parts onto Si Substrates at Liquid-Liquid Interface

引用

Chinese Physics Letters 2006年第1期23卷 42-44页

作者：刘梅张建刚吕曜夏善红 State Key Laboratory of Transducer Technology Institute of Electronics Chinese Academy of Sciences Beijing 100080

We report a new approach for the self-assembly of cuboid micro-parts onto Si substrates to construct three-dimensional microstructures. To perform assembly, the Si substrates are prepared with a deep cavity array as binding sites. An aggregate composed of hundreds of uniformly aligned micro-parts is formed at the C10F18-H2O interface. The micro-parts are arranged by passing the substrate through the aggregate of micro-parts, thus the micro-parts are left on the substrate, and then the substrate is vibrated ultrasonically in the solution, making it possible for the micro-parts to fall into the cavities on the substrate. Finally the substrate is pulled out of the solution after assembly. This technique could give a high yield of up to 70%, providing a new method for micro-assembly.

Transforming the cost of solar-to-electrical energy conversion: Integrating thin-film GaAs solar cells with non-tracking mini-concentrators

Practical solar energy solutions must not only reduce the cost of the module,but also address the substantial balance of system ***,we demonstrate a counter-intuitive approach based on gallium arsenide solar cells that can achieve extremely low-cost solar energy conversion with an estimated cost of only 3% that of conventional gallium arsenide solar cells using an accelerated,non-destructive epitaxial lift-off wafer recycling process along with a lightweight,thermoformed plastic,truncated mini-compound parabolic concentrator that avoids the need for active solar *** solar cell/concentrator assemblies whose orientations are adjusted only a few times per year,the annual energy harvesting is increased by 2.8 times compared with planar solar cells without solar *** results represent a potentially drastic cost reduction in both the module and the balance of system costs compared with heavy,rigid conventional modules and trackers that are subject to wind loading damage and high installation costs.
