Displaying items by tag: PhotovoltaicsNumberland engineering consultancy for new processes, new materials. New processes: We analyse, optimize and document processes often not covered by quality management handbooks and teach them to run. We translate technical demands into physical effects or properties and then find the suitable material.http://numberland.de/index.php/get-in-contact/itemlist/tag/Photovoltaics2016-07-01T21:10:45+02:00Joomla! - Open Source Content ManagementThin films with less costs2015-09-28T09:33:21+02:002015-09-28T09:33:21+02:00http://numberland.de/index.php/get-in-contact/item/1504-thin-films-with-less-costsAdministratorgrond@numberland.de<div class="K2FeedImage"><img src="http://numberland.de/media/k2/items/cache/8b48a3d3ff200010263c0fc8d232b3ac_S.jpg" alt="Thin films with less costs" /></div><div class="K2FeedIntroText"><h1><span style="display: inline; float: none; position: static; font-size: 14px; font-weight: bold; font-family: Tahoma,Arial,sans-serif; font-size-adjust: none; font-style: normal; font-variant: normal; line-height: 14.3px; text-align: left; text-decoration: none; text-indent: 0px; text-shadow: none; text-transform: none; word-spacing: normal;">Thin films with less costs</span></h1> </div><div class="K2FeedFullText"> <p>ID: F1509-10</p> <p>Scientists are developing photovoltaic technologies based on chalcogenide elements in their quest to further reduce the manufacturing price of solar modules. Copper indium gallium diselenide (CIGS) photovoltaics (PV) is one of the three main PV thin-film technologies utilized in solar cells. Despite having currently entered the mass production phase, it currently relies on costly and hard to control vacuum-based deposition procedures. Experts initiated the task to develop a non-vacuum-based alternative with environmentally friendly procedures based on nanoparticle electrodeposition of the precursor material. This procedure results in better precursor lateral homogeneity. Project members are focusing on enhancing solar mobile architectures by growing zinc oxide nanorod arrays on a transparent conductive oxide (TCO) layer by electrodeposition. In situ, online quality control and monitoring strategies are being developed to scale up non-vacuum procedures in large-area substrates. Besides electrodeposition, researchers are working on validating and developing alternative processes to create the next generation of chalcogenide-based cells and modules. Electrostatic spray-assisted vapour deposition (ESAVD) and chemical vapour deposition had been a number of the techniques showing the greatest promise. Kesterite absorber materials had been examined for their suitability as replacement material for the scarcely available indium in future thin-film solar cells. Experts have actually already identified precursor systems for additional optimisation and reliably produced them using effortlessly scalable technology. They've effectively demonstrated an effectiveness of up to 12 % in a CIGS electrodeposited layer on a 30 x 60 cm2 area. A kesterite device from electrodeposited metal precursors features been developed and chalcogenide layers based on ESAVD have actually additionally been deposited on a cup substrate. Also, the very first TCOs have been synthesised by employing electrodeposition, ESAVD or compound bath deposition. The end products are expected to show efficient energy conversion at significantly reduced costs contrasted to conventional deposition techniques.</p> <p><a href="mailto:getincontact@numberland.com?subject=Get%20in%20Contact">getincontact@numberland.com</a></p> <p>&nbsp;</p></div><div class="K2FeedTags"><ul><li>Thin</li><li>Film</li><li>Photovoltaics</li><ul></div><div class="K2FeedImage"><img src="http://numberland.de/media/k2/items/cache/8b48a3d3ff200010263c0fc8d232b3ac_S.jpg" alt="Thin films with less costs" /></div><div class="K2FeedIntroText"><h1><span style="display: inline; float: none; position: static; font-size: 14px; font-weight: bold; font-family: Tahoma,Arial,sans-serif; font-size-adjust: none; font-style: normal; font-variant: normal; line-height: 14.3px; text-align: left; text-decoration: none; text-indent: 0px; text-shadow: none; text-transform: none; word-spacing: normal;">Thin films with less costs</span></h1> </div><div class="K2FeedFullText"> <p>ID: F1509-10</p> <p>Scientists are developing photovoltaic technologies based on chalcogenide elements in their quest to further reduce the manufacturing price of solar modules.
