A New Generation of Amorphous Silicon Solar Panels
Superior Performance under high-temperature conditions
-
Crystalline-Si PV modules lose some power-generating capability with rises in temperatures. But Amorphous-Si PV modules generate heiger power during summar time.
Amorphous-Si PV modules can deliver maximum performance.
Superior lighting absorption
-
Amorphous silicon PV module (a-Si) has superior light absorption per nominal watt power. Compared with mono-crystalline silicon
PV modules (c-Si) or poly-crystalline silicon PV modules (poly-Si), it generates considerably more power per nominal watt power.
Assuming that the total solar radiation per year (1.323kWh/m2) is 100%, Amorphous Silicon PV can produce 90.95% of actually
generated watt-power, much higher than that of other crystalline silicon PVs (80 to 84%).
Environmentally friendly, Shorter Energy Pay-back Time (EPT)
-
The single junction a-Si layer can be made extremely thin.The thickness of a-Si cell is 0.3μm, which is 1/600 of
that of crystalline silicon cell (approx. 200μm).
This means that a-Si cell less material and energy thereby enabling high productivity for mass production.
EPT is the time a PV module to "pay back" the energy used in its manufacture by its own power generation.
The EPT of a-Si PV is 1.1 years, which is approximately 16 months shorter than that of crystalline silicon PV (2.7 years).
EPT is one of the most important aspects when evaluating the ecological benefit of PV systems.
