Project details

Short description

Project F4 takes solution ALD (from C1) to applications by demonstrating its use for depositing the light absorber layer in efficient solar cells. The project closes the ChemPrint cycle of innovation by combining atomic-level control in solution processing with performance quantifiers (with F3). It provides direct comparisons of processing techniques, between sALD and gALD on the one hand and between sALD and evaporation-based methods on the other hand (with F3), and demonstrate how the control of chemical bonds between deposit and substrate determines function (with S2, S3, S4, S5, F5, M2).
