Abstract
Hybrid photodiodes (HPD) systems are on the rise. The growing interest on these devices is mainly due to their power in
image sensing and bioengineering solutions. In this work, a new class of donor-acceptor dendrimers was synthesized and incorporated,
along with a ruthenium sensitizer dye, into low cost devices comprised of one single layer of a biocompatible matrix (agarose). Exploring
different electrodes, low current devices with a counter-electrode dependent response have been successfully assembled at room temperature.
Using a stainless steel electrode, sensitized donor-acceptor dendrimers provide photodiode-like systems having nA dark currents.
