Thin Film
SunPerfect’s a-SI thin film PV panels maintains great advantages over
conventional crystalline wafer based panels:
• Consumes only 1/600 th of the scarce silicon used in crystalline wafers.
• No heavy metals or other toxic chemicals used in many other PV products.
• Efficient in high temperature environments such as summer time, compared to
crystalline wafers whose performance dramatically degrades in high temperature
climates.
• As an excellent light absorber, the a-Si thin film panel starts generating power
at first light in the morning through sunset, unlike crystalline wafers which have a
much narrower power generation curve. While the nominal efficiency of a
crystalline wafer may be higher than a a-si thin film wafer at high noon, the actual
daily, monthly and annual efficiency output of a-SI thin film panel is dramatically
higher than for crystalline PV.
• Ability to produce semi-transparent, the a-SI thin film panel is suitable for
installation as high-rise glass walls at a minor power output reduction. Building
occupants can see the outside directly through PV panels that are powering the
building!
• The a-SI thin film panels have dimension of 1300mm x 1100mm size, (approx
4’2’’x3’8’’). This means a much lower interconnect is required compared to arrays
of small crystalline wafers, leading to greater system reliability. The panels can
be handled, installed and moved with conventional construction equipment and
tools. Each panel weighs just 25 kgs (55 lbs).
