The relationship between man and nature has always been a problem. In recent years, the emergence of fireflies has become more and more precious in the city. The death of fireflies is caused by human damage to the environment, which causes damage to the firefly habitat. The long-distance transport of fireflies causes the firefly’s living environment to change. Therefore, the author wants to solve the problem of the relationship between environment and fireflies and human beings through bio-photovoltaic materials that are completely harmless to the environment. The aim is to simulate “firefly” in the city, to express the topic of the environment and to provide a way to protect nature; Reveal the principles and characteristics of bio-biophotovoltaic materials. Help the people understand cutting-edge technology. Promote the application and popularization of related biological materials.

In the early stage, the author tested the power generation and stability of bio-photovoltaic materials. Try to explore the viability of materials to provide electricity. On this basis, the power generation principle and power generation mechanism of the material are displayed by means of graphs and videos. After repeated comparisons, the author finally chose soil microbes and chlorella as the basic materials for bio-power generation. Select the light rotation structure to simulate the firefly flash signal and motion trajectory. And consider the interaction of human cultivation of plants. Finally, complete the science experience series based on bio-photovoltaic materials based on the firefly experience device. This design is both a reflection of the relationship between man and nature, as well as an application exploration that reveals the characteristics of biological materials.
