説明:

The global warming trend has made the world realize the importance of cooling technologies. Peltier devices potentially save 10-times energy consumption compared to only air conditioners being used, because of their capability of directly cooling down human body. Yet, commercial Peltier devices are still heavy, solid, and small. To mass-produce lighter-weight larger-area thinner Peltier sheets via a roll-to-roll process, we have developed sticky thermoelectric materials, hierarchically designed at atomic scale, nano scale, and micro scale. However, thought thinner Peltier sheets enable to physically enhance the cooling heat flux capability further, they require higher current at the maximum operating point, which ruin their cooling performance due to Joule heating on electrodes. In this study, we researched the macro-scale patterning of sticky TE materials and electrodes and discovered a stripe pattern being 14~23% better than the traditional check pattern. The simpler pattern could benefit mass production.
