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.
