Findings from I. Ahmad and Colleagues Update Understanding of Solar Energy

May 30, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- New research on Solar Energy is the subject of a report. According to news reporting from St. Petersburg, Russia, by VerticalNews journalists, research stated, "In this paper, we report a new cost effective platinum-free counter electrodes (CEs) for dye sensitized solar cells (DSSCs). The CEs were produced using Graphene Nanoplatelets (GNPs) or multi-wall carbon nanotubes (MWCNTs) or various weight % of hybrid GNPs and MWCNTs mixtures."

The news correspondents obtained a quote from the research, "These materials have been dispersed using PEDOT: PSS polymer and then deposited on fluorine doped tin oxide (FTO) glass as well as on a non-conducting glass substrate by a drop casting method. The testing of these electrodes in DSSCs have demonstrated a power conversion efficiency of up to 4.10% to compare with the power conversion efficiency of 3.90% for the DSSC with a standard Pt based CE. New CEs were also made where both Pt and FTO were completely replaced by the hybrid PEDOT: PSS-GNPs-MWCNT nanomaterials."

According to the news reporters, the research concluded: "The DSSC with these new platinum- and FTO-free CEs have demonstrated an efficiency of up to 2.48%."
