面向光伏能源的宽带光子收获生物分子
摘要
我们讨论了人工光合作用用于光伏能量转换的关键原理。通过考察所谓“染料敏感型太阳能电池”(DSSC)的工作过程来展示这些原理——这是一种仿生自然系统中典型特征的光电化学器件，其在纳米结构膜上进行电荷分离。此类器件有望在光伏市场低成本、中等效率领域挑战硅半导体技术。 currently used as the photon harvesting components in DSSCs. They produce a relatively broad band UV and visible response, but have long term stability problems and are expensive to manufacture. We suggest that a class of biological macromolecules called the melanins may be suitable replacements for the ruthenium complexes. They have strong, broad band absorption, are chemically and photochemically very stable, can be cheaply and easily synthesized, and are also bio-available and bio-compatible. We demonstrate a melanin-based regenerative solar cell, and discuss the key properties that are necessary for an effective broad band photon harvesting system.
