Efficient energy from spherical solar cells

spherical solar cells
Japanese are a serious rage in the tech and environmental world, they hardly let a day pass before they are up with something novel again in either sphere – Texas Instruments was probably the first ever to build Solar cells – that plays a brainwave for Japans Clean Venture 21, which takes the solar notion to a new height, developing Spherical Silicon Solar Array.

Unlike the conventional and contemporary – where the efficiency rate with the Texas’ innovation was just 10% and cost enormous – the Clean Venture enhancement is 5 times cheaper and uses 5 times less material, consuming half the energy to reproduce.

With good optical properties and made into 1mm by dripping (rather than cutting) these silicon cells are put into little reactors, measuring 2.2 to 2.7mm in width, the sunlight is absorbed from all possible angles for generating power with better efficiency and flexibility. Spherical shaped cells also utilize the retro type flat arrays.
