[1] Silicon solar lgcells with conductive transparent polymeric layers / A. B. Chebotareva, G. G. Untila, T. N. Kost et al. // Proceedings 25th European Photovoltaic Solar Energy Conference. — WIP Munich Munich, 2010. — P. 747–750. Transparent conducting polymer films are used to attach current collecting grid of wire to silicon solar cell surface covered by antireflection TCO layer in Laminated Grid Solar Cell (LGCell) construction during low temperature lamination step. Application of the most transparent among the tested conductive thermoreactive polymers based on polydifenylenephthalide (composition PS08) in LGCell contact system leaded to the increase of spectral response and higher stability of LGCell construction to the UVA illumination. Now another type of conductive polymers - thermoplastics (polyarilenesterketones) with softening point above 160oC are considered as possible candidate to form stable LGCell current collecting system. A new synthesized polymer VS152 shows low contact resistivity in the system Metal /VS152/ TCO (0.2÷0.5 mΩ·cm2) but has worse transparency. Bifacial LGCells with transparent conducting polymers PS08 and VS152 are made on the similar IFO/(n+pp+)Cz-Si/ITO structures. Also for the first time PS08 polymer is used to produce LGCells on laser textured mc-Si with pillar array structures with aspect ratio in the range of ≥3 (depth to width). Polymer solution effectively fills the cavities on the extended surface and provides excellent optical and electrical properties of LGCells. [ DOI ]
