New generation materials for organic photovoltaic applications

German specialty chemicals producer Merck is embarking on a partnership with Nano-C, a developer of nano-structured carbon, for use in energy and electronics applications.
Both companies aim to jointly develop and commercialize advanced semiconducting materials and formulations for applications in organic photovoltaics (OPV). Additionally, adding to its base of OPV materials, Merck will distribute PCBM fullerene derivative products, a family of semiconducting materials commonly used in OPV applications.
The collaboration will target the development of material systems to go beyond the performance limitations of current-generation OPV materials. It will bring together Merck's extensive experience with organic semiconducting materials and Nano-C's unique know-how and intellectual property in fullerene derivatives.
Novel material concepts produced using intelligent design will enable power conversion efficiency values in excess of 10%, thereby creating new and broader market interest in organic photovoltaic technologies.
Under its lisicon® brand, Merck is actively working on novel organic semiconducting materials for electronic and photovoltaic applications at the Chilworth Technical Centre, its chemicals research site near Southampton, UK. Merck recently invested in the expansion of the Chilworth Technical Centre by adding new chemistry and OPV application testing laboratories to intensify and accelerate new material and formulation developments for the photovoltaics industry.
Two years ago, Nano-C announced an exclusive license from Unidym/Siemens of PCBM, a fullerene derivative widely used in the OPV industry. In addition, approximately one year ago Nano-C received EPA (Environmental Protection Agency) clearance for fullerene and PCBM manufacture on a commercial scale supporting the drive to full commercial availability.
