Abstract
The invention illustrates an innovative way to fabricate low cost, efficient, rigid or flexible mesoscopic optoelectronic devices such as photovoltaic (PV) solar cells or photo sensors (b) comprising three-dimensional arrays of semi-conductive micro- or nano-pillars () deposited from suspensions e.g. by inkjet printing. Said pillars additionally increase the surface area of the device composed of an interpenetrating network of semiconductor particles of mesoscopic (2-50 nm) size forming junctions. In the present invention the active surface area is significantly increased when compared to previous flat structures (a,), being fabricated preferably by inkjet patterning. Additionally, the invention allows for production of much more functional devices when compared with conventional mesoscopic PV cells due to smaller structure density what makes the layer more resistive to mechanical failure when bending. The invention also describes the device substrate (), contact and electrode (), ion conductor () and fabrication parameters (h, d).
