Abstract
Organic photovoltaics (OPV) have the potential for low production cost. Additionally, there has been an increase in both efficiency and stability of small-area OPV devices prepared in research laboratories worldwide and, consequently, attention on OPVs has increased tremendously. In this chapter we describe the challenges of OPVs and give suggestions on how these can be overcome. Design and synthesis of a new group of materials and low band gap polymers are described. Problems and possible solutions of OPV stability are shortly discussed. Furthermore, the latest technology to manufacture large-area OPV modules is described along with production of large-area modules by roll-to-roll printing of a low band gap polymer.
