Technology
A researcher
of National Institute of Materials Science developed a solar battery that has a
new structure to increase the generation of a silicon solar battery to 100
times as compared with the existing one. Naoki Fukata lined an infinite number
of peaked micro silicon bars to increase the area that receives sunlight. Theoretically,
it is possible to decrease the area to one hundredth for the same generation
capacity. That is, a 5 x 5 m solar battery installed on the roof can be made
smaller to a 5 x 5 cm solar battery. That is, the new solar battery will be installable
regardless of the place with easiness of maintenance.
The newly developed solar battery has numerous standing peaked silicon bars, each of
which is about 5 micrometers long and 90 nanometers in diameter, at intervals
of about 100 nanometers on the surface. This structure made it possible to
convert the light whose wavelength is less than 600 nanometers that has been
wasted. Accordingly, it has become possible to get 100 times more generation capacity
per area as compared with the existing structure that piles up silicon
materials. Because a small solar battery can maintain a certain amount of generation
capacity, the newly developed solar battery will very suitable for
solar-tracking generation equipment. The research group plans to put the new
technology into practical application in five years.
