Registration Date 29-02-2024 Organization Department for special training National academy of science of Ukraine at Kiev University popup.description1 To develop a hybrid photoconverter based on organic and polymer heterojunctions with backside porous photonic crystal reflectors. Organic semiconductor photoconverters are a cheap alternative to traditional Si solar cells (SCs). Their production requires investigations to improve the efficiency, increase the lifetime, and reduce cost. In this work, new promising organic semiconductor materials of the melanin family to apply as SC active layers will be investigated. Porous photonic crystals (PFCs) will be used for the first time as controllable backside reflectors to increase the organic SC efficiency. In this work, the PFCs will be functionalized with nanoparticles and polymer to ensure spectral response in the given spectral range and obtain the required mechanical properties. popup.nrat_date 2024-12-09 Close
