Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Donor-acceptor bulk hetrojunction (BHJ) organic solar cells are fast emerging as a potential, futuristic, flexible, large area cost effective technology. Power conversion efficiency (PCE) more than 10% has already been achieved in these solar cells using tandem structures of the device. The two important steps in polymer solar cells include the efficient light harvesting and efficient transport of charge carriers. As regards efficient harvesting of photons the approaches being followed include modification/tailoring the band gap of existing electron donating polymers or developing entirely new polymers. To achieve high efficiency of PSCs, one of the most critical challenges at the molecular level is to develop ideal p-type conjugated polymers that simultaneously possess sufficient solubility, low band gap, and high hole mobility to ensure high PCE for organic photovoltaics. Semi-random co-polymers containing multiple distinct acceptor monomers is one approach to achieve large current densities and high efficiency due to favourable properties such as semicrystallinity, high hole mobility, and importantly broad, uniform, and strong absorption of the solar spectrum. 164 pp. Englisch. …

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The book emphasis the designing of fly ash based Nano composite pigments for NIR reflective coatings. Work synergy of two Nano materials is created for producing multi functional core shell composites for use in low cost NIR reflective coating applications. The book gives an overview of core shell composite materials containing core of fly ash and different metal oxides in the shell like TiO2, ZnO and CeO2. Effective formation of shell of TiO2 on core of fly ash was achieved by using an anionic surfactant, sodium dodecyl sulfate (SDS) by solvent route. Nano titania coated fly ash composite pigments were used for the preparation of cool coatings. In the same way, ZnO coated fly ash and ceria coated fly ash composite was fabricated for their near infra red reflective property so as to find its applications as cool pigments.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Ce livre met l'accent sur la conception de pigments nanocomposites à base de cendres volantes pour les revêtements réfléchissants dans le proche infrarouge. La synergie de travail de deux nanomatériaux est créée pour produire des composites coeur/enveloppe multifonctionnels destinés à être utilisés dans des applications de revêtement réfléchissant le proche infrarouge à faible coût. Le livre donne un aperçu des matériaux composites coeur/enveloppe contenant un coeur de cendres volantes et différents oxydes métalliques dans l'enveloppe comme le TiO2, le ZnO et le CeO2. La formation efficace de l'enveloppe de TiO2 sur le noyau de cendres volantes a été obtenue en utilisant un tensioactif anionique, le dodécylsulfate de sodium (SDS) par voie solvant. Des pigments composites de cendres volantes recouverts de nano titane ont été utilisés pour la préparation de revêtements froids. De la même manière, des cendres volantes enrobées de ZnO et des cendres volantes enrobées de cérium ont été fabriquées pour leur propriété de réflexion dans le proche infrarouge afin de trouver leurs applications comme pigments froids.…
