Micro-structured substrates for LT, with the optimized parameters indicated by the modelling tasks (WP3), uniformly patterned over large-areas (>10 cm2)

This deliverable will show the fabrication of transparent and opaque flexible substrates containing an area of 10 cm2 uniformly patterned by a longrange ordered hexagonal array of microcavities with the dimensions determined in WP3 Such photonic structure will be patterned via a scalable and lowcost softlithography method that combines a colloidal lithography technique to fabricate the stamps with a hotembossing process to imprint on the substrates Means of verification the benefits of the implementation of optimized LT structures will be experimentally verified in WP4 by comparing the fabricated cells with reference devices Indicator PSC performance KPI1 objective PSC cells with efficiency 22
