Thin films with lesser defects

ID: F1601-03

Nano-scale slim films have become an important component of numerous products. Novel optical technology to detect and repair defects during production will improve quality and durability, and increase competitiveness. Tiny defects in slim movies utilized in items such as polymer-coated paper and low-cost, flexible photovoltaics (PVs) can decrease product quality and durability. This additionally decreases yield and increases scrap levels, more impacting competitiveness. Exposure of such defective PV modules and polymer-coated paperboard barrier movies to water vapour causes short circuits in electronics and the degradation of paper items. In-line quality control examination systems alleviate some of the burden, but there's frequently a trade-off between quality and speed. As a new task nears completion, experts have actually developed revolutionary optical strategies for existing optical measurement systems that detect smaller defects faster. Gas cleaning after examination has been introduced whereas cleaning and localised fix to eliminate particles produced during manufacturing will be introduced in the next phase. Laboratory tests have actually demonstrated a really promising decrease in problem densities of more than 90 %. One demonstrator and one proof-of-concept detection system have been implemented for each line. Ongoing trials are creating excellent results and the final demonstrators will showcase the new detection, cleaning and repair technologies. The technologies will be integrated with modern high-throughput roll-to-roll processing to increase production performance and decrease production expenses. Improved defect detection and fix will improve the quality and life time of products employing large-area thin movies, improving the competitive position of manufacturers. It'll also reduce waste, decrease costs and translate to crucial advantages for the environment. Brand new markets in smart packaging, flexible electronics and large-area lighting can be expected for the companion organizations.

    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.

      A project is redesigning multi-junction thin-film silicon products to facilitate change from lab- to pilot-scale manufacturing. Innovative processes for light management and brand new absorber materials are boosting module efficiencies and reducing manufacturing expenses. Multi-junction solar-cell devices allow for higher transformation efficiencies contrasted to the conventional ones. However, such efficiencies are gained at the cost of increased complexity, with substrate geometries and layer interacting with each other greatly impacting the product overall performance. Experts are re-designing multi-junction thin-film silicon devices to facilitate change from lab- to pilot-scale manufacturing. Revolutionary procedures for light management and new absorber materials are boosting module efficiencies and reducing manufacturing expenses. Experts are concentrating on improving the fill factor and open-circuit voltage to boost the final power conversion performance of the thin-film silicon modules. The target is to demonstrate prototypes with 12 % efficiencies at costs below EUR 0.5 per Watt-peak. Novel textured substrates are increasing light-trapping in thin movies. The texturisation is achieved with nano-structures obtained by certain layer deposition methods such as chemical etching and nanoimprinting on cup. Experts have actually developed equipment for wet-chemical etching of transparent conductive oxide layers made of double-structured zinc oxide. Work on nanoimprinting on large-area modules is progressing as prepared. Doped and absorber layers are examined, examined and integrated for validation in products. Novel absorber materials consist of nanocrystalline silicon oxide levels for the top cell and surface-passivated nanocrystalline silicon layers for the bottom cellular. Especially, the development on textured substrates needs to be explored to determine its impact on the structural and electronic properties of the levels. By evaluating optical and electrical designs, the designs for module development will be selected. Work on high-rate deposition of nanocrystalline silicon bottom cells is ongoing. The first standardised round-robin tests have actually been performed at various organizations and institutes. an expense evaluation features been performed for nano-imprint lithography.
