A research team from Washington State University claims to have developed a new manufacturing process to produce cadmium telluride (CdTe) PV panels that is 45% cheaper than current industry standards. Solar cells made on a laboratory scale have reached efficiencies close to 22%, while modules made with fully automated in-line machines show efficiencies above 18%. “Adding the highly volatile dopants during the feedstock manufacturing process also eliminates the need to dope after film deposition which can cause non uniformity issues,” said research co-author, Tawfeeq Al-Hamdi. With annual production capacity of 1.9 GW in its Ohio manufacturing facilities, First Solar is the largest U.S. PV Today, First Solar is producing CdTe modules with 16% efficiency and a manufacturing cost below USD $0.46/Watt. raw material and equipment suppliers, various manufacturing associated costs and the actual process. A novel manufacturing process for fabricating CdS/CdTe polycrystalline thin-film solar cells Open-air printing is much faster and much less expensive. Save my name, email, and website in this browser for the next time I comment. Unlike crystalline modules, the manufacturing process of thin-film modules is a single process that can not be split up.. For CdTe - thin-film, 220kg are required for 1MWp, which is 36 times less weight per kWp than crystalline silicon. The schematics of CdS/CdTe Solar cell is shown in Fig 1. Using the most advanced techniques, record efficiencies have been achieved by a few groups, indicating the potential of the CdTe thin-film solar cell.In 1984 the magic limit of 10% efficiency was surpassed by a group at Kodak laboratories, using close-spaced sublimation (CSS) [19]. The II-IV semiconductor compound, CdTe, has suitable electrical and optical properties as photovoltaic and high-energy radiation sensor material. 3 Onto this is first sprayed a Transparent Conducting Oxide (often referred to as the TCO) layer. CdTe-based solar cells Cadmiumtelluride (CdTe) is a widely used absorber material for thin-film solar cells. Production of CdTe-based solar cells involves the application of a variety of thin layers on a transparent substrate (usually glass with special diffusion-blocking layers) such as transparent conductive oxides (TCOs), CdTe, and CdS. The CdTe crystals are grown in a high-pressure Bridgman furnace, which is a kind of industrial furnace utilized for crystal growth and directional solidification of polycrystalline ingots. Overall CdTe solar cell performance was significantly improved after the discovery of a cadmium chloride (CdCl 2) vapor treatment. It takes a long time, the tubes are not reusable, and the silica glass is limited in how much heat, mass, and pressure it can take. Typical CdTe thin-film deposition techniques include: close-spaced sublimation, vapor-transport deposition, physical-vapor deposition, sp… CdS/CdTe solar cells have achieved gigawatt-scale commercial production at a lower cost than traditional crystalline silicon photovoltaics. Manufacturing CdTe solar cell is cheaper due to its significantly low raw material consumption. This may result in undesirable shortened carrier lifetime and degradation of the CdTe solar cell. 2,5 CdTe Thin Film Solar Cell Market concurrentiepositie en Trends.

Furthermore, First Solar recently announced that they have produced a thin film PV module with full area efficiency of 18.2%. The researchers claim, however, that the technique is scalable to large volumes, and that the process may enable the production of crystals that are up to 20 kg. Emiliano joined pv magazine in March 2017. This annealing process is accomplished in the presence of oxygen at temperatures near 390°C after the CdTe layer is grown on the CdS layer and prior to … Cells come in many sizes and shapes. Solar cells can be categorized according to the applied production process and used materials, for example in crystalline and thin-film solar cells. A critical step in solar cell manufacturing is metallization through screen printing. 2008). The conducting layer can be made from one of a variety of materials, including zinc oxide, indium oxide, indium tin oxide (ITO), and strontium oxide. The current manufacturing process involves synthesizing the CdTe material in a sealed quartz tube to contain the reaction.
