Prospective Life-Cycle Modeling of Quantum Dot Nanoparticles for Use in Photon Upconversion Devices

Quantum dot nanoparticles (NPs) can be used in several applications, for example, photon upconversion devices that increase the electricity output of solar modules. In order to facilitate life cycle assessment (LCA) studies such this study provides ready-to-use LCA unit process data four NPs suitable applications: cadmium selenide, sulfide, lead and sulfide. The is provided two prospective scenarios: one optimistic pessimistic. An impact conducted assess NPs’ climate change performance, where solvent-related processes as steam production recycling hazardous waste treatment are shown hotspots. To show applicability data, a module with an layer investigate whether it preferable from perspective install more modules or equip existing ones devices, leading produced both cases. shows need become 0.05–2 percentage points efficient per gram applied, depending on scenario, preferable.
