Solar cells inorganic nanoparticle

Despite of many advantages of DSSCs, still lower efficiency compared to commercialized inorganic solar cells is a challenging area. Recently, one-dimensional nanomaterials, such as nanorods, nanotubes and nanofibers, have been proposed to replace the nanoparticles in DSSCs because of their ability to improve the electron transport leading to enhanced electron collection efficiencies in DSSCs. 

Intensive research has been devoted to the field of bulk heterojnnction solar cells during the last decade. As a result, many different materials were found to be suitable for construction of bulk heterojnnction solar cells. Among them are examples of polymer/polymer, polymer/small molecule, polymer/carbon nanotube, polymer/inorganic nanoparticle, as well as small molecule/small molecule composites. ...

Enhancement in absorption can be achieved by proper engineering of these metal-dielectric structures in which light can be concentrated and folded into a thin semiconductor layer. Performance of thin film cells can be improved significantly by incorporation of metallic nanoparticles deposited on top of photoactive layer or inside the buffer layer on both organic and inorganic solar cells as verified experimentally [14].
