Chlorophyll solar cell

Chlorophyll in plants is extracted and placed into artificially prepared membranes that produce electricity when exposed to light. This is the chlorophyll battery.

At present, the world consumes at least 13 megawatts (1 megawatt = 1 trillion watts) of energy each year. The non-renewability of fossil fuels such as oil determines that people must look for alternatives.

The sun, which has a power of 120,000 watts, has entered the sight of the people. In theory, as long as collecting 1 hour of solar energy, it can meet the human energy needs throughout the year.

In order to effectively collect solar energy, people have tried various methods, such as the development of large-area, high-efficiency, low-cost solar cells. There are currently industrialized crystalline silicon (monocrystalline, polycrystalline silicon) solar cells, some of the thin-film batteries (amorphous/microcrystalline silicon-silicon-based thin films, cadmium telluride, and copper indium gallium selenide) that have been put into production, and those that are mainly under research. Dye-sensitized batteries, organic thin-film batteries, etc.

A chlorophyll solar cell has attracted much attention because it mimics photosynthesis in the natural world as much as possible.
