Solar cells based on atmospheric plasma synthesis and surface engineered Si-/C-quantum dots.

摘要

Si- and C-nanomaterials with strong quantum confinement and engineered energy bandgap exhibit unique properties used in many fields of applications (e.g. solar cells, biology, optoelectronics). In this contribution, we demonstrate that a confined atmospheric plasma interaction through liquid media is a suitable technique for the synthesis and/or surface treatment of Si- and C-quantum nanomaterials. Two different plasma-liquid sources are applied for synthesis and surface engineering: a femtosecond (fs) laser beam (100 fs) is used to generate a plasma in the liquid; and an atmospheric pressure direct-current (dc) microplasma is generated under ambient air conditions and coupled to the colloid via a counter electrode.
