Micromorph Tandem Thin Film Solar Module

Tandem thin film modules technology is comprised of an amorphous top cell, which converts the visible part of the sun’s spectrum, and the microcrystalline bottom cell absorbs light in the infrared spectrum.

 

Because of this double layer, the technology boosts the efficiency level by approximately 50% over traditional amorphous single cells, which also allows converting more sunlight into electricity. With a low temperature coefficient for output power, thin film generates greater energy than its crystalline silicon counterpart in geographic regions where it is cloudy, high temperature and high latitude. In warm climates this translates into more kilowatt-hours per kilowatt.

Advantages

 

• Tandem-junction structure (a-Si – amorphous silicon / μc-Si – microcrystalline silicon) captures a wider part of the solar spectrum, converting more sunlight into electricity.
• The tandem structure with an additional μc-Si absorber on top of a-Si layer, which converts the energy of the red and infrared spectrum, is allowing increasing efficiency.
• Amorphous silicon alloy thin film is more cost effectively and absorbs light more than its crystalline counterpart.
• Microcrystalline layer provides superior long-term stability and higher module efficiency.
• Modules are sized to optimize the greatest amount of power, easily handled by one person.
• Heavy duty corrosion-resistant anodized aluminum frame and weather-resistant junction box with pre-mounted MC cables ensuring dependable performance and easy installation or maintenance.
• High-impact tempered glass to resist hail, ice, flying debris or strong wind.
• 25-year limited warranty on power output.
