Scientists from Solliance, the cross-border thin-film solar cell research alliance, have produced the world’s first organic photovoltaics (OPVs) to be made exclusively with inkjet printing processes. The processes offer complete flexibility of cell shape, substrate and structure, and are ideal for rapid product development and prototyping. Moreover, they enable easy up-scaling to volume manufacturing of cost-effective products. OPVs promise low-cost solar cells that can be made in different col...
