Abstract :
We have developed a liquid crystal polymer (LCP) film applicable to the substrate in the roll-to-roll manufacturing of thin film silicon solar cells. LCP film has excellent and balanced properties of high thermal resistance, high dimensional stability and low moisture absorption compared to other super engineering plastics such as PES or PAR. Microcrystalline silicon solar cells with a nip structure (/spl sim/2 /spl mu/m) are fabricated on the textured LCP substrate at 180/spl deg/C, demonstrating a high short-circuit current density (25.8 mA/cm/sup 2/) due to effective light trapping. As a result, we have achieved an efficiency of 8.1%.
