Developers at VTT Technical Research Centre of Finland have recently created a 3D printed tree that actually harvests solar energy. The tree is fitted with flexible solar panels that are shaped as leaves and made from printed organic photo-voltaic cells.
The cells are roughly 0.2 mm thick, and when about 200 leaves are assembled together, they can generate 3.2 amperes of electricity and 10.4 watts of power.
The energy is ran through a power converter and then it can be used to power small devices such as cellphones and laptops.
This new development is only a prototype so as the technology advances this idea can be replicated on a larger and more efficient scale, and it can possibly be used to harness even more energy in the future.
