1. Development Status

In the past two hundred years, the massive use of non-renewable energy sources has led to a rise in oil prices and greenhouse effect that has serious consequences for our ecological environment. At this time, Photovoltaic power generation, which is one of the important members of new energy, come to our mind. At present, the main photovoltaic power generation method uses the photoelectric effect of semiconductor to perform light-to-electric conversion. When used, it has the advantages of no regional restrictions, but the inadequacies are also obvious. In the production of photovoltaic panels, high pollution and high energy consumption problems are inevitable, in addition to the high cost and insufficient conversion rate.

3. Our Project

And our project is based on the background of globalization, through the method of synthetic biology to propose a new idea for the traditional photovoltaic industry: to study a commercially viable device from light to electricity. Compared to solar cells, our devices not only can perfectly play the role of batteries, but also avoid environmental pollution and solve the problem of excessive power plant footprint. We increased the production of Shewanella by increasing the lactic acid production of cyanobacteria and Rhodopseudomonas pallidum. At present, the production of Shewanella can reach 20%, which is enough to replace the solar panels with 17%~18% of electricity produced on the market today.
