创新背景

能源利用发电在近几年科学发展加持下逐渐转向自然可再生绿色能源利用，开发无害低碳的太阳能和风能，光伏发电已成为能源发电的重要组成部分。但太阳能发电受到天气和太阳光线存在的影响仍旧存在限制，生物光伏研究对于解决这一问题有巨大助力。

创新过程

生物光伏利用植物通过叶绿素进行光合作用，将太阳能转化为化学能并贮存在内部的能量将光能转化为电能。生物光伏利用微生物代替传统太阳能电池板作为广电转换材料，减少转换过程排出的废物，环保、地毯且成本较低，带给光电转化和能源利用具有良好的效果。

2022年英国研究人员将已使用一年的生物光伏供电研究成果发表在《能源与环境科学》杂志上。研究使用一种广泛存在的蓝绿藻为微处理器，指利用环境中的光和水，持续供电一年，整个系统具有可靠和可再生供电小型设备的潜力。

研究装置的藻类供电系统利用其中包含的集胞藻进行光合作用，从太阳中获取能量产生微小电流，将电流与铝电极相互作用后为微处理器供电。

集胞藻是一种单细胞蓝藻，通过光合作用可产生乙醇、氢、正丁醇、异丁醇和潜在的生物柴油。这种藻类作为生物光伏原料，不需要喂食，进行光合作用时会自行产生食物，在无光照的情况下也会继续处理食物，持续产生电流，保证了电流产生的持续性，不受光照供给的影响。

供电系统材料成本低廉，且材料普通、可回收，具有极高的环保效能。它不仅储存能量，而且通过光电转化自行产生能量，可以在短时间内快速生产复制，投放于偏远地区，用源源不断产生的少量电力为地区服务。

生物光伏的利用生产有利于促进光电转化发展，为节约能源合电力供应提供了环保高效的解决方法。

Innovative use of bio-photovoltaics to power small devices

Biophotovoltaic utilizes the photosynthesis of plants through chlorophyll, which converts solar energy into chemical energy and stores the energy inside to convert light energy into electricity. Biophotovoltaic uses microorganisms to replace traditional solar panels as radio and television conversion materials, reduces waste discharged during the conversion process, is environmentally friendly, carpeted, and has low cost, bringing good effects to photoelectric conversion and energy utilization.
In 2022, British researchers will publish their one-year-old biophotovoltaic power supply research results in the journal Energy and Environmental Science. The study uses a widespread blue-green algae as a microprocessor, which means that the entire system has the potential to reliably and renewable power supply small devices by using light and water in the environment to continuously supply electricity for a year.
The research device's algae power supply system utilizes the Synechocystis contained within it for photosynthesis, harvesting energy from the sun to generate a tiny electrical current that interacts with aluminum electrodes to power the microprocessor.
Synechocystis is a unicellular cyanobacteria that produces ethanol, hydrogen, n-butanol, isobutanol, and potentially biodiesel through photosynthesis. This kind of algae, as the raw material of biophotovoltaic, does not need to be fed. It will produce food by itself during photosynthesis. In the absence of light, it will continue to process food and continuously generate current, which ensures the continuity of current generation and is not supplied by light. Influence.
The material cost of the power supply system is low, and the materials are common and recyclable, and have extremely high environmental protection efficiency. It not only stores energy, but also generates energy by itself through photoelectric conversion, which can be quickly reproduced in a short period of time, put in remote areas, and serve the area with a small amount of electricity that is continuously generated.
The utilization and production of biophotovoltaic is conducive to promoting the development of photoelectric conversion, and provides an environmentally friendly and efficient solution for energy saving and power supply.
