The paper presents an approach to inkjet print optical volumes, using the specific hybrid polymer ORMOCER and an optimized, multilayer inkjet printing process to achieve shape deviations <20 µm PV, surface roughness in the range of <50 nm and a transparency of the printed bulk volume >95 %.enapplication programsink jet printingoptical multilayerspolymer solar cell620conference paper
