‘Hydrangea’ solar panel beautifies PV energy production

University of Tokyo professor, Hiroshi Segawa, has developed a solar cell designed as a floral artwork.

Besides looking great, the hydrangea‑inspired dye‑sensitised solar cell generates and stores enough energy to charge a smartphone twice, with the components stored in decorative wooden cube frames. The energy generated by the device is stored in the flower, with the petals turning increasingly blue as it charges and changing to white as it is used.

The technology is clearly not aimed for high‑volume energy production and instead targets applications where aesthetics are important. The tongue‑in‑cheek approach is aimed at developing ‘enjoyable energy’ and promoting solar energy in a way that is fun and approachable for everyday use – something inconspicuous that blends in with home décor.

It is similar to other PV‑integrated objects, such as the ‘Soofa’ park bench and ‘Solar Tree’ car port, in that the energy production is a value‑add piece and not the primary function of the object. We can now add decorative PV to the growing list of PV applications.

  1. Hello, I am interested in Hydrangea solar panel beautifies PV energy production. Do they come in 2kW or above? how much is the approximate price of it.

    Look forward to receiving your early response.
