Researchers created a new generation of biological photovoltaic system

Thus creating double bacteria biological photovoltaic system has realized the efficient and stable power output, the maximum power of 150 mW/m2 density, higher than that of the current single bacteria biological photovoltaic system is generally more than 10 times. Algae absorb light energy and CO2 fixation for synthesis of d - energy carrier Lactic acid, shiva's bacterial oxidation d - Lactic acid to generate electricity, thus forming a d - from photons Lactic acid to directional electron flow of electricity, from the energy of the light energy to chemical energy to electrical energy conversion process. Biological photovoltaic ( biophotovoltaics, BPV） Provides a biological path for solar energy utilization. Network monitoring system on the development and use of renewable energy is the only way for realizing the sustainable development of human society. Pinhole camera is 20 yuan, however, the current BPV system output power is low, more than 3 orders of magnitude lower than the solar photovoltaic (pv). Using continuous flow and cultivating mode, solar photovoltaic system engineering support the double bacteria biological can implement more than 40 days of stable power output, and the average power density to achieve higher level of 135 mW/m2, in electricity production time, single output power both to the highest levels of the BPV system currently. In order to improve the BPV photoelectric conversion efficiency, the Chinese Academy of Sciences institute of microbiology Li Yin team to design and create a directional synthesis microbiome of electron flow, to solve the problem of cyanobacteria weak electricity production activity directly. Biological photovoltaic (pv) of photosynthetic microorganisms ( Such as blue-green algae) As photovoltaic materials with carbon neutral, good environmental compatibility and the potential characteristics of low cost, is expected to become more environmentally friendly a new generation of solar power generation technology. However, part of the photovoltaic materials containing toxic elements, recovering waste large and difficult to total solar panels, and photovoltaic device manufacturing process involves the use of toxic and harmful chemicals. With the improving of the energy conversion efficiency and reduce manufacturing costs, global solar photovoltaic capacity has more than 500 GW.

this is used in the world with the synthesis of microbial groups of directional electron flow create photovoltaic (pv) of the first reports, is also China's first biological photovoltaic prototype device. In direct transform algae to strengthen its electricity production activity, at present there is no report of success. The main reason is blue-green algae and photosynthetic microbes are of high photosynthetic efficiency, solar engineering support but electrogenesis activity is very weak. Through genetic engineering machine, water heater environment and the design, modification and optimization on the level of device, the researchers effectively overcome the physiological incompatible problem between two kinds of microorganisms. The synthesis of microbial groups by a can store energy in d - Lactic acid engineering cyanobacteria and an efficient use of d - Lactic acid is produced electricity of shiva's bacteria ( As shown in figure) 。 No back condole ark how fixed in the synthesis of microbes in the group, d - Lactic acid is energy carrier between the two kinds of microbes. As the most abundant and renewable energy, solar energy utilization of basic and applied research has important scientific and practical significance. Photovoltaic power generation is the main form of solar energy utilization, and its core technology is the use of semiconductor materials convert solar energy into electric energy. The study proves that the use of the synthesis of microbial groups of directional electron flow can remarkably improve the BPV photoelectric conversion efficiency, breaking the biological photovoltaic efficiency and lifespan is difficult to improve the inherent understanding, in order to further improve BPV photoelectric conversion efficiency laid the important foundation. With the further promotion of solar photovoltaic (pv) use, its potential negative impact on the environment can not be ignored. Intelligent systems engineering
