nTriple-junction
cells reduce light-induced degradation
Each cell is composed of three
semiconductor junctions stacked on top of each other. The bottom
cell absorbs the red and infrared photons, while the middle cell
absorbs the green photons and the top cell absorbs the blue
photons. This spectrum splitting capability is the key to higher
efficiency and reduction in light-induced degradation.

nLightweight, durable
and flexible, making it ideal for portable solar cells
Solar energy efficiency is closely
related to the photons absorption from solar spectrum.
The solar spectrum is
electromagnetic radiation made up of a range of
wavelengths.

Crystalline modules have good
response in the red part of the visible spectrum. We see this
type of light on clear winter days. The modules have a high
relative outdoor efficiency when the sunlight intensity is high
(1,****1,**0 W/m2).
Thin-film amorphous Silicon (a-Si)
modules have good response in the blue part of the visible
spectrum. We see this type of light in the summer and on cloudy
days (diffuse light). The modules have higher relative
outdoor efficiency when the sunlight intensity is low (*****0
W/m2).
Shading caused by bird dropping,
water pudding, concentration of dust or dirt, ash zone and leaves
can easily reduce the output of photovoltaic module and in
serious cases even shut down the entire module completely.
Therefore, the combination of construction and design of
photovoltaic module is essential for the outdoor
efficiency.
A-Si modules, use unique material
and technology, reduce output power loss caused by the shading
and soiling effect to less than 4.5%.
