Leybold Optics reserve opening systems for CIGS applications

2011-09-01 21:37:10 – Owing to a potency values that can be achieved, CIGS in a meantime depends as skinny film record with a biggest expansion potential.

Leybold Optics GmbH, a internationally behaving association shaped in Alzenau/Germany, is seen as a pioneering retailer of opening systems for CIGS applications. According to experts(1), a share of skinny film modules of several technologies in a universe marketplace will boost to 30 percent.

CIS or CIGS skinny film modules include of I-III-VI devalue semiconductors that are used in several combinations. The shortening CIGS stands for a elements that are used: copper (Cu), indium (In), gallium (Ga) and/or selenium (Se). There is a good intensity for assets in CIGS record – not usually as distant as appetite output is concerned, though also in honour of element and prolongation costs. Thanks to a thinner covering thicknesses and depending on a substrate, stretchable

solar modules can also be manufactured.

Leybold Optics offers a full operation of apparatus for all opening shaped CIGS processes, be it on potion substrates or stretchable substrates. In a initial step, a substrate, for instance glass, is primarily coated with molybdenum (Mo) that serves as behind contact. Then a absorber is constructed from a elements copper, indium and gallium, with successive heating in a selenium atmosphere. The final, conductive and pure front hit consists of an aluminium-doped zinc oxide (AZO). Buffer layers that are for instance done of indium sulphide (In2S3 CdS) and non-doped zinc oxide (ZnO) are located between absorber and front contact. The molybdenum and zinc oxide layers are constructed by means of sputtering. For these applications, Leybold Optics offers plane (H-series) as good as straight (A-series) sputtering systems. The absorber on a discordant might be constructed by means of thermal evaporation or by burn cloaking followed by successive heating in a selenium atmosphere.

Especially for this selenium routine – though also for other applications – Leybold Optics has grown a selenium evaporator Selenia. The complement that is already successfully marketed works with linear selenium sources, ensuring an glorious covering congruity even during intensely vast throughputs. The element of Selenia permits a selenium fountainhead to be replenished during using production. The complement can be used for all formidable evaporation processes on prosaic substrates for photovoltaic applications. In perspective of a tiny amounts of selenium used, a high grade of productivity, a elementary operation and low upkeep requirements, Selenia is a singular resolution that has an intensely certain outcome on a cost of ownership.

The RaPiT (Rapid Thermal Process Oven) rounds off a operation of products offering by Leybold Optics to furnish a critical absorber layer. The semiconductor is shaped inside a RaPiT with a assist of a reactive gas. In team-work with a customer, a RTP furnace was grown by Leybold Optics with a pattern of assembly a high mandate on a difficult routine control and accurate heat guidance, while concurrently achieving top levels of productivity.

Further routine stairs to request a aegis and a successive front hit covering are compulsory to finish a CIGS solar cell. In this honour too, a appurtenance platforms of a Leybold Optics H- and A-series with their analogous pattern for a prolongation of a zinc oxide (ZnO) and unique zinc oxide (i-ZnO) layers significantly minister to a make of solar cells in prolongation lines.

For complex, stretchable applications, Leybold Optics offers a Roll-to-roll cloaking system, also called web-coater. The routine is designed for substrates such as steel films or stretchable fake materials and permits cloaking methods such as sputtering, evaporation, CVD (chemical effluvium deposition) or total solutions. The substrates are ecstatic around a circuit from hurl to hurl and are opening coated in a process, totally though touching a coated surface. With a special 360° design, a law Leybold record offers a entirely involuntary process, that detached from a prolongation of stretchable solar cells also permits serve focus ranges.

All systems offer a entirely involuntary routine that not usually allows a prolongation of stretchable solar cells though also a accumulation of other applications. In a meantime, CIGS systems from Leybold Optics are being used in vast prolongation comforts by universe marketplace leaders. All products from this skinny film dilettante are characterised by their high grade of reliability, accessibility and flexibility. Depending on a preferred processes, a complement concepts can be of straight or plane design.

Company Profile:
Leybold Optics GmbH is one of a world’s heading suppliers of opening technology. It also develops processes and manufactures formidable high-end coatings. This conjectural skinny film dilettante sets milestones in a fields of sputtering, PEVCD, plasma assisted evaporation, automation and software. It is organized into dual divisions: Optics and Glass Solar. The Glass Solar multiplication portfolio comprises opening systems for a photovoltaic attention and machines that are used to cloak architectural glass, displays and other large-area applications. The Optics multiplication markets deposition systems for pointing optics, ophthalmic lens coating, a automotive and a wiring industry.

The substructure mill of a success was laid over 160 years ago by a founders and inventors Ernst Leybold and Wilhelm Carl Heraeus. Their pioneering suggestion and loyalty to investigate and a growth of new prolongation procedures is reflected in a marketplace standards that have gained worldwide approval given a association was founded. Today, Leybold Optics, that is traditionally committed to creation and quality, is a tellurian association that has some-more than 500 employees opposite a world.
