摘要

Three independent European CIS manufacturers of different countries, a big player in glass coatingindustry, three universities and three research institutes work together in the EU project “LARCIS” in order toadvance CIS manufacturing at high yields on glass substrates. The two main approaches for the realisation ofenhanced module efficiencies at reduced costs are inline co-evaporation of Cu(In,Ga)Se_2 and electrodeposition of theCuInSe_2 (CIS) precursor. Alternative back contacts such as ZrN and TiN with high optical reflection have been testedand molybdenum layers with enhanced conductivity for homogeneous electrodeposition on 30 × 30 cm~2 have beenDC sputtered. A chemical-bath-deposited Cd-free ZnS based buffer has been applied on both CIS types resulting inhigh photocurrents and efficiencies which are at least as high as reference cells with CdS buffers. In parallel, an In_2S_3buffer has been evaporated ex situ from powder with a certified maximum efficiency of 14.16 %. Solar cells of up to17.8 % efficiency (certified, with ARC) were fabricated by using co-evaporated multi-stage CIGS from an inlinereactor. CuIn(Se,S)_2 was electrodeposited homogeneously on substrate areas of 30 × 30 cm~2. The mean efficiency oftest cells distributed on this area was <8 %>.
