Abstract:
ECN is developing n-i-p solar cells based on a-Si and µc-Si absorber layers deposited with inline PECVD, using linear plasma sources, on an imprint-textured UV curable coating layer on foil. We show that solar cells deposited on foil with random texture can achieve good light trapping (Jsc ~ 15-16 mA/cm2 for a-Si cells). Furthermore, we show that a-Si nip cells on foil, processed in dynamic mode in an industrial pilot roll-to-roll system for 30 cm wide foils, can achieve efficiencies of over 7%. Future work will focus on developing and implementing optimised periodic nanotextures for ?c-Si and micromorph tandem.
