Kazusa DNA Research Institute developed a basic technology of solar battery installable on the farmland that hardly impairs the growth of farm products. The new technology generates electricity using only short-wavelength light and transmits long-wavelength light vital to the growth of farm products. The newly developed solar battery is translucent, and two kinds of electrodes and electrolytes are put between the two sheets of glass. Pigment molecules attached to the surface of the electrodes absorb light with a wavelength of 400-600 nanometers, which is equivalent to the wavelength of blue and green, to generate electricity, while transmits long-wavelength light like red vital to the growth of plants.

This technology will help Japanese farmers stabilize management of their farmland because the deregulation enacted by the government at the end of March allowed farmers to get revenue from selling electricity. In fact, the number of farmers involved solar sharing by which they can sell electricity by photovoltaic generation while managing their farm business is on the rise.
