Photonic sintering of inkjet printed current collecting grids for organicsolar cell applications
article
ITO-free organic solar cells with inkjet printed current collecting grids are demonstrated.For sintering those grids, thermal treatment and its faster alternative, photonic flash sinter-ing, are applied and the characteristics of the resulting metal structures are compared witheach other. The electrical potentials and resulting currents in the devices with differentsintering conditions are calculated. The flash sintered current collecting grids exhibit clearadvantages over thermally sintered grids in terms of geometry and conductivity. Similarconductivities are obtained after 5 s of flash sintering and 6 h of thermal sintering. Thisfinding demonstrates the great potential of flash sintering for the roll-to-roll manufactur-ing of printed organic solar cells on flexible substrates.
