SOLLIANCE An R&D cluster bringing thin film solar energy technology to excellence
CIGS technologies: Performance and roadmap - What is it? - Why do you want it? - How is it made? - How can it be used? - How will it develop in the future? Technodag CIGS Stichting KIEN Ando Kuypers Program manager CIGS TNO - Solliance
Solliance: 3 Solliance: a thin-film solar R&D collaboration Solliance was founded in 2011, supported by Province of Noord Brabant with 28 Million investment to strengthen industry in the region Shared research facilities and 250 fte researchers with a focus on thin film Si, OPV and CIGS

9 CdS: Cadmium Sulfide is geel Jaarproduktie CdS pigment: 2000 ton (Wikipedia) Gewicht Heineken krat = 2 kg Bevat 0,1% Cd = 2 gram (2005-2008: 28000 ton Heineken granulaat verwerkt = 28 ton Cd ) Gewicht CIGS paneel = 16,6 kg Bevat 0,00065 % Cd = 0,11 gram (30 nm CdS komt overeen met 0,14 gram CdS /m 2 ) 4 december 2014
10 Why CIGS? Less than 3 µm thickness is enough to absorb visible light in single pass Only thin film technology that competes with crystalline-si in efficiency (next to CdTe) More kwh per kw p (high performance ratio) Light soaking (underrating of W p specifications) Temperature coefficient Low light performance Can be produced directly on many different (construction) materials: glass, metal, polymers Can be produced in many different ways Widest variety of module concepts Highest potential for midterm cost reduction 4 december 2014
