Popis: | International audience; Passivating contacts of crystalline silicon (c-Si) solar cells with a poly-silicon layer (poly-Si) on a thin siliconoxide (SiOx) film offer an interesting approach to decrease the recombination current at the metal/c-Si interface and toincrease the cell efficiency. This study focuses on the development of boron-doped poly-Si layers deposited by PlasmaEnhanced Chemical Vapour Deposition (PECVD) on top of a thin silicon oxide film. First, the deposition and annealingconditions were optimised in order to: (1) reduce the blistering of the poly-Si on the thin SiOx film and (2) improve thepoly-Si conductivity. The passivation properties of the resulting structures have been shown to depend on the blister densityand have been improved through a hydrogenation step leading to a maximum implied open-circuit voltage value of 721 mV. |
