Thin Film Solar Cells - An Efficient Option for Harvesting Solar Energy Amorphous silicon (a-Si) solar cells: These were one of the earliest commercial Thin Film Solar Cells technologies. a-Si cells have efficiencies in the range of 6-13% but have relatively low production costs. However, the performance degrades over time. Cadmium telluride (CdTe) solar cells: CdTe cells are currently the most prevalent thin film technology accounting for over 10% of the global PV . They have efficiencies around 16-22% and excellent light absorption properties. However, cadmium is a toxic element raising environmental concerns.
