(775e) CIGS Nanocrystal Solar Cells on Plastics and Paper
This presentation summarizes our work using Copper Indium Selenide (CIS) nanocrystal inks to build solar panels on a variety of low cost, heat intolerant substrates. CIS nanocrystal PVs have been fabricated using a variety of print methods on plastics such as polyethylene terephthalate (PET) and cellulose nanofiber paper, with champion devices reaching 2.8% and 2.25% respectively. Devices on paper demonstrated no performance loss even when flexed up to 100 times at a 5 mm radius. Additionally, devices with over 2% efficiency were demonstrated with all printed window layers.
