Role of polysilicon in poly-Si/SiOx passivating contacts for high-efficiency silicon solar cells

IBC c-Si solar cells based on ion-implanted poly-silicon passivating contacts

Ion-implanted poly-crystalline silicon (poly-Si), in combination with a tunnel oxide layer, is investigated as a carrier-selective passivating contact in c-Si solar cells based on an interdigitated back contact (IBC) architecture. The optimized poly-Si passivating contacts enable low interface recombination, resulting in implied VOC (iVOC) of about 720 mV and 704 mV for n-type and p-type, respe...

High Efficiencies in Nanoscale Poly(3-‎Hexylthiophene)/Fullerene Solar Cells

   A modified morphology was introduced for poly(3-hexylthiophene):phenyl-C71-butyric acid methyl ester (P3HT:PC71BM) bulk heterojunction (BHJ) solar cells by thermal and solvent annealing treatments in the presence of hydrophilic-hydrophobic block copolymers. Power conversion efficiency (PCE) plummet was prohibited during both thermal and solvent treatments for all BHJ devices modified wit...
