Among suchdevices, there is currently a growing interest in the development of user-oriented andmultipurpose systems for intelligent packaging or on-site medical diagnostics, whichwould greatly benefit from printable solar cells as their energy source for autonomousoperation.This chapter first describes and analyzes different types of cellulose-based substrates forflexible and cost effective optoelectronic and bio devices to be powered by printed solarcells. Cellulose is one of the most promising platforms for green recyclable electronicsand it is fully compatible with large-scale printing techniques, although some criticalrequirements must be addressed. Paper substrates exist in many forms. From commonoffice paper, to packaging cardboard used in the food industry, or nanoscale engineeredcellulose (e.g. bacterial cellulose). However, it is the structure and content of paper thatdetermines its end use. Secondly, proof-of-concept of optoelectronic and bio devices producedby inkjet printing are described and show the usefulness of solar cells as a powersource or as a chemical reaction initiator for sensors.
