Photovoltaic effect of a thiophene substituted diarylethene polymer film
Abstract:Diarylethenes having thiophene unit show low oxidation potential to afford polymer film by electrochemical polymerization. The thickness of the polymer deposit on the electrode was conveniently controlled by the number of the potential cycles. The polymeric films showed reversible photocurrent generation property, by the alternative irradiation with a light. The photo-electrode prepared from a mixture of diarylethene and an electroactive monomer or nanoparticles showed much increased photocurrent generation with faster response An all solid type photocell structure was prepared to show high open circuit voltage (Voc) of 0.79 V under a simulated sunlight (100mW/cm2).

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.
