2. SUNCERAM II CELLS FOR INDOOR USE
2.1. General Information
The Sunceram II cells for indoor use thin-film
compound semiconductors, and they are ideal for
powering loads such as calculators which use very low
levels of power and which are used under other types of
indoor lighting. In particular, they deliver a high power
output under long-wavelength light from incandescent
lamps, etc., and they can power calculators even under
low brightness levels of 10 lux and below. Their unique
and original pastel shades of color produced by the
fabrication methods involving printing and sintering
lend an added softness to the products in which they are
used.
2.2. Features
•
These cells have a high spectral sensitivity to light
ranging over a broad wavelength spectrum. When
they are used in a product under an incandescent
light, they deliver 5 times more power than
amorphous silicon solar cells (in internal testing).
•
It is possible to set an operating voltage that suits
the application at hand because the solar cells are
formed on the glass substrates and also because any
number of series connections can be made.
•
Due to the printing type production method, it is
possible to produce solar cells with sizes that match
their applications.
•
These
cells are highly reliable as solar cells for
indoor consumer products.
2.3. Applications
•
Calculators
•
Indoor clocks
•
Remote control units
•
Indoor digital thermometers
•
Other indoor consumer products which have a low
power consumption
