OPERA (New OPportunities with low environmental footprint and Earth abundant absorbeRs for solAr cells)

The OPERA project aims at developing a new kind of low-cost, indium/gallium-free, non-toxic nitride absorber and to realize first test nitride cell by using easy-to-use, up-sizeable and cost affordable production technique (sputtering). This is an ambitious goal that would be a major step forward in the field of solar energy.
