Langues : Américain (ame) Catégories : Photopiles Revêtement antireflet Verre Index. décimale : 667.9 Revêtements et enduits Résumé : We propose a new antireflection (AR) design for organic photovoltaics (OPVs) to achieve broadband and omnidirectional enhancement of photocurrent. In the proposed design, a hybrid AR structure, which combines moth eye texturing and two-layer interference coating, is integrated with a glass substrate having a high refractive index (n). Using the optical simulation for OPV cells, we compare the performance of various AR configurations upon changing the refractive index of the glass substrate. We show that the short-circuit current density (JSC) is decreased by using the high-n glass substrate without AR coating, whereas JSC is significantly increased by applying the high-n glass substrate with the hybrid AR structure, suggesting an importance of the integrated design. In addition, we demonstrate that the proposed AR configuration is quite effective to attain broad angle performance and is robust against the variations in geometric features of moth eye texture. Finally, the spectral dependence of photocurrent generation is experimentally measured for the verification of the effectiveness of the integrated AR design. These results provide a practical and efficient AR technique that can further expand the potential of OPVs as energy supply devices.

Anti-reflective smart coatings on glasses / Praful Sanjay Dahatonde in PAINTINDIA, Vol. LXIII, N° 6 (06/2013)  

[article]  inPAINTINDIA > Vol. LXIII, N° 6 (06/2013) . - p. 62-66 Titre : Anti-reflective smart coatings on glasses Type de document : texte imprimé Auteurs : Praful Sanjay Dahatonde, Auteur Année de publication : 2013 Article en page(s) : p. 62-66 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Matériaux intelligents Polymérisation sous plasma Revêtement antireflet:Peinture antireflet Verre Index. décimale : 667.9 Revêtements et enduits Résumé : Our eyes are very complex organs. In order for our eyes to see, there must be light. Light rays reflect off of an object and enter the eye through the cornea. At the back of the eye the light is focused by the retina, and then it is converted into electric signais to be sent to the brain. Once the brain receives the signais, vision occurs. If the eye cannot properly focus an image it is said to have a refractive error. An eye doctor can determine the type of refractive error by a test cal led refraction. Correcting a refractive error is achieved by glasses, contacts or refractive surgery. A type of optical coating applied to the surface of lenses and other optical devices to reduce reflection. Anti-reflective coating (AR coating) is made of several layers of film metal oxides that are layered on the surface of the lens. Each layer is chemically engineered to block reflected light. This causes the intensity of the light reflected from the inner surface and the light reflected from the outer surface of the film to be nearly equal, canceling each other out and el iminating glare. Antireflection coatings are used to reduce reflection from surfaces. Whenever a ray of light moues from one medium to another (such as when light enters a sheet of glass alter travelling through air), some portion of the light is reflected from the surface (known as the interface) between the two media. AR was first developed to enhance and improve the view on high powered telescopes, microscopes and camera lenses. AR coating is composed of multiple layers of metal oxides applied to the front and sometimes the back surface of the lens. This layeringeffect reduces reflected light and aliows more I ight to betransmitted through the lens. What does this do for eyeglasses? First, it improves the appearance of your eyes to the outside world. AR coating makes the lenses appear almost invisible. It also vastly improves the cosmetic appearance of wearing the lenses by reducing internai reflections in the lens, making your lenses appear much thinner. Secondly, it improves the quality of your vision by reducing reflected lights. This cuts down on glare and halos around lights, and improves the quality of your vision at night and when us ing the computer in certain work environments. While AR coating is beneficial to everyone, it is found almost universally on high index lenses. High index lenses are made out of a type of plastic that can make your lenses much thinner than regular plastic lenses. However, to achieve th is thinness, sometimes the lens material can cause unwanted reflections. As a result, manufacturers who produce very high index lenses make AR a part of the complete lens price and do not separate the lens from the AR coating because they bel ieve a very high index lens should never be worn without an AR coating.

Antireflective coatings / Saurabh Kusurkar in PAINTINDIA, Vol. LXIII, N° 9 (09/2013)

Langues : Anglais (eng) Catégories : Anti-réflectance Revêtement antireflet:Peinture antireflet Tags : 'Revêtement  optique'  Interface  Antireflet  'Images  fantômes'  Optoélectronique  'Interférence  destructive' Index. décimale : 667.9 Revêtements et enduits Résumé : An optical coating is one or more thin layers of material deposited on an optical component such as a lens or, mirror, which alters the way in which the optic (Glass ) reflects and transmits light. One of the types of optical coating is an antireflection coating, which reduces unwanted reflections from surfaces. As light passes through an uncoated glass substrate, approximately 4% will be reflected at each interface. This results in a total transmission of only 92% of the incident light. Applying an AR coating on each surface will increase the throughput of the system and reduce hazards caused by reflections traveling backwards through the system (e.g. ghost images). Antireflection (AR) coatings have been widely employed in optical and optoelectronic materials, a decrease in light reflection, and thus an increase in the transmittance of light, enables clear viewing with the eyes of glass and displaying surfaces. AR coatings find its application to Image sensors, Lithograph; Light-emitting diodes (LEDs) are a common solid state light source. Also in camera lenses, Solar panels etc where loss of light by reflection is the loss of output and quality of the product. The principle of AR coating is based on the destructive interference of reflected light from interfaces between air and a film.
