Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

ITO nanoparticles (INPs) with abundant ?OH groups are introduced to promote the uniform self?assembly of SAM molecules in inverted PSCs. The assembly of SAM can also be reinforced due to the strongly bonded ?OH groups on INPs, inhibiting its desorption during solvent rinsing and long?term aging. Resulting PSCs show high efficiency of 26.44% with good operational stability under ISOS?L?2 protocol, retaining, retaining ?91% of initial efficiency after MPP tracking for 1000 h at 85 °C.Recently, inverted perovskite solar cells (PSCs) show rapidly improved efficiency with the use of self?assembled molecules (SAM). However, device stability remains a challenge due to the easy desorption of the SAM molecule. Here, functionalized indium tin oxide nanoparticles (INPs) are introduced to promote and reinforce the self?assembly of SAM on the substrate. INPs contain abundant ?OH groups to uniformly anchor SAM molecules. Importantly, different from traditional physically absorbed and easy?desorbed ?OH in ITO substrate, the ?OH groups on INPs are stably bonded, resistant to solvent rinsing and long?term aging, thus inhibiting SAM desorption during device aging. As a result, PSCs with INPs exhibit high efficiency of 26.44% with good operational stability under ISOS?L?2 protocol, retaining ??91% of initial efficiency after maximum power point (MPP) tracking with continuous illumination at 85 °C.
