This revolutionary design multiplies the efficiency of solar panels by allowing capture light from all directions. These solar cells with spherical shape and small size that could make a major revolution in the expansion and scope of solar photovoltaic energy.
Sphelar, the product developed by the Japanese company Kyosemi, consists of a new solar cells with spherical shape and tiny size between 1 and 1,5 mm in diameter, Unlike traditional flat cell 72 mm. The breakthrough could mean a revolution in solar PV.
Sphelar, consists of an array of small spherical solar cells that can absorb solar radiation at any angle, can take advantage of both the reflected and diffuse radiation, technology with the use of fans and efficiency need not exceed reaches 20%.
The arrangement of cells in a flexible and transparent medium, extends the range of applications for solar PV, as the ability to incorporate in small electronic devices or convert large glazed surfaces as generators. Its application in Spain would reduce the visual impact, especially in large cities and tourist areas.
According to the company, production costs are halved, manufacture compared to conventional silicon cells, since silicon is used efficiently used both in the manufacture of the cells and the subsequent production of energy.
