光生物电化学系统是一种新兴的可再生能源。通过利用光合作用，它们将光能转化为电能。这项研究评估了一种简单、可扩展的生物电化学系统，该系统由回收塑料瓶建造，配备了由回收铝制成的阳极，并与绿藻小球藻一起运行。我们测试了这种被称为生物瓶伏(BBV)装置的系统是否可以在户外长达35天的时间内运行。电化学表征是通过测量阳极和阴极之间的电位降来进行的，该值被用来计算电荷积累的速度。BBV系统最初能够提供~500mC·瓶−1·天−1，在整个实验过程中增加到最大~2000mC·瓶−1·天−1。电输出持续且显著高于无藻细胞运行的非生物BBV系统(~100mC·瓶−1·天−1)。对藻类生物量积累速度的分析支持这样的假设，即从藻类细胞中收集一定比例的电子不会显著干扰藻类的生长速度。我们的发现表明，生物电化学系统可以使用回收的组件来建立。这些系统的原型已经在公共活动中展示；它们可以作为学校的教育工具包，也可以为离网供电的低能量设备提供解决方案。
Photobioelectrochemical systems are an emerging possibility for renewable energy. By exploiting photosynthesis, they transform the energy of light into electricity. This study evaluates a simple, scalable bioelectrochemical system built from recycled plastic bottles, equipped with an anode made from recycled aluminum, and operated with the green alga Chlorella sorokiniana. We tested whether such a system, referred to as a bio-bottle-voltaic (BBV) device, could operate outdoors for a prolonged time period of 35 days. Electrochemical characterisation was conducted by measuring the drop in potential between the anode and the cathode, and this value was used to calculate the rate of charge accumulation. The BBV systems were initially able to deliver ~500 mC·bottle−1·day−1, which increased throughout the experimental run to a maximum of ~2000 mC·bottle−1·day−1. The electrical output was consistently and significantly higher than that of the abiotic BBV system operated without algal cells (~100 mC·bottle−1·day−1). The analysis of the rate of algal biomass accumulation supported the hypothesis that harvesting a proportion of electrons from the algal cells does not significantly perturb the rate of algal growth. Our finding demonstrates that bioelectrochemical systems can be built using recycled components. Prototypes of these systems have been displayed in public events; they could serve as educational toolkits in schools and could also offer a solution for powering low-energy devices off-grid.
