Descripción
The optoelectronic properties of chemically synthesized colloidal nanoparticles can be promising for functional materials, as those required for high efficient photovoltaic (PV) devices. In particular, appropriately designed semiconductor colloids (quantum dots, QDs) can potentially allow subbandgap current generation in intermediate band solar cells? while metal nanoparticles (MNPs) sustaining surface plasmons can provide both near and farfield light trapping to further boost the generated power. The incorporation of colloidal particles in inorganic PV materials is not trivial, therefore their implementation has so far been restricted to organic/polymeric based solar cells. In this work, PbS colloidal QDs have been incorporated in the intrinsic aSi: H layer of HIT (substrate/aSi: H heterojunction) test structures. Both cSi and GaAs substrates have been used, and in some cases colloidal Au NPs have also been included. The obtained devices are meant as probes to verify the feasibility of incorporating foreign nanoparticles in a cell structure and not as potentially efficient solar cells. Despite the radical novelties incorporated, the devices behaved similarly to the references, thus proving the compatibility of the proposed materials and processes.
