| Περίληψη: | The employment of printing techniques as cost-effective methods to fabricate low cost,
flexible, disposable and sustainable solar cells is intimately dependent on the substrate
properties and the adequate electronic devices to be powered by them. Among such
devices, there is currently a growing interest in the development of user-oriented and
multipurpose systems for intelligent packaging or on-site medical diagnostics, which
would greatly benefit from printable solar cells as their energy source for autonomous
operation.
This chapter first describes and analyzes different types of cellulose-based substrates for
flexible and cost effective optoelectronic and bio devices to be powered by printed solar
cells. Cellulose is one of the most promising platforms for green recyclable electronics
and it is fully compatible with large-scale printing techniques, although some critical
requirements must be addressed. Paper substrates exist in many forms. From common
office paper, to packaging cardboard used in the food industry, or nanoscale engineered
cellulose (e.g. bacterial cellulose). However, it is the structure and content of paper that
determines its end use. Secondly, proof-of-concept of optoelectronic and bio devices produced
by inkjet printing are described and show the usefulness of solar cells as a power
source or as a chemical reaction initiator for sensors.
