Nanocrystal/Polymer Composite Photovoltaic Devices
Abstract:Unlike conventional solar cells, novel polymeric photovoltaic devices have flexibility, large area processibility and potential low costs. We have constructed devices consisting of a composite of CdSe nanocrystals and poly(3-hexylthiophene). The resulting monochromatic power conversion efficiency is 0.7 %. Since the efficiency in these devices is limited by poor electron transport, we seek to improve the mobility of electrons in the CdSe with nanorods in place of nanocrystals. Devices fabricated with small aspect ratio CdSe nanorods and poly(3-hexythiophene) have enhanced conversion efficiencies up to 2 %. To further increase device efficiencies, soluble nanorods of CdSe were synthesized with aspect ratios reaching 20:1 by controlling the kinetics of nanocrystal growth in lyothermal solutions.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
