生物光电技术是一种很有前途的可再生能源技术，因为它依靠生物有机体作为廉价的、自我修复的和容易获得的催化剂，从丰富的资源--阳光--中产生电力。然而，生物光电电池的效率仍然明显低于合成材料。在这里，我们设计了一个平台来利用小型化几何所提供的大功率密度。为此，我们开发了一种不需要膜或介质的微流控生物光电器件的软光刻方法。聚囊藻属。PCC6803细胞被注入并被允许在阳极上沉降，允许细胞和电极之间的物理接近要求无介质操作。在白光下，当叶绿素浓度为100μM时，我们证明了功率密度超过100mW/m2，这对于没有额外能量供应的生物光电器件来说是一个很高的值。

英文摘要：
Biophotovoltaics has emerged as a promising technology for generating renewable energy since it relies on living organisms as inexpensive, self-repairing and readily available catalysts to produce electricity from an abundant resource - sunlight. The efficiency of biophotovoltaic cells, however, has remained significantly lower than that achievable through synthetic materials. Here, we devise a platform to harness the large power densities afforded by miniaturised geometries. To this effect, we have developed a soft-lithography approach for the fabrication of microfluidic biophotovoltaic devices that do not require membranes or mediators. Synechocystis sp. PCC 6803 cells were injected and allowed to settle on the anode, permitting the physical proximity between cells and electrode required for mediator-free operation. We demonstrate power densities of above 100 mW/m2 for a chlorophyll concentration of 100 {\mu}M under white light, a high value for biophotovoltaic devices without extrinsic supply of additional energy.
