Nanomaterials and nanostructures for efficient light absorption and photovoltaics
nt matter & 2011 n.2011.10.002 thor. Tel.: +852 23 [email protected] (Z. Abstract Nanomaterials and nanostructures hold promising potency to enhance the performance of solar cells by improving both light trapping and photo-carrier collection. Meanwhile these new materials and structures can be fabricated in a low-cost fashion, enabling cost-effective production of photovoltaics. In this review, we s...
متن کاملPorous Nanomaterials for Ultrabroadband Omnidirectional Anti-Reflection Surfaces with Applications in High Concentration Photovoltaics
John A. Rogers, and co-workers demonstrate broadband anti-reflection coatings that rely on porous nanomaterials formed by selfassembly. The image shows the use of such coatings (orange) on an array of lenses within a concentration photovoltaics architecture, where photons are efficiently concentrated onto underlying triple-junction solar cells, leading to an efficiency enhancement of ≈8%. POROU...
متن کاملOrganic photovoltaics
In the last ten years, the highest efficiency obtained from organic photovoltaics (OPVs), such as bulk heterojunction polymer:fullerene solar cells, has risen from 2.5 to 11 %. This rapid progress suggests that the commercialization of OPVs should be realized soon if we can solve some technical issues. The advances in the development of OPVs can be attributed to four fronts: (i) a better unders...
متن کاملMolecular photovoltaics.
The dye-sensitized nanocrystalline injection solar cell employs transition metal complexes for spectral sensitization of mesoporous TiO(2) films together with suitable redox electrolytes or amorphous organic hole conductors. Light harvesting occurs efficiently over the whole visible and near-IR range due to the very large internal surface area of the films. Judicious molecular engineering allow...
متن کاملMolecular Photovoltaics in Nanoscale Dimension
This review focuses on the intrinsic charge transport in organic photovoltaic (PVC) devices and field-effect transistors (SAM-OFETs) fabricated by vapor phase molecular self-assembly (VP-SAM) method. The dynamics of charge transport are determined and used to clarify a transport mechanism. The 1,4,5,8-naphthalene-tetracarboxylic diphenylimide (NTCDI) SAM devices provide a useful tool to study t...
