"Spicy world of NanoScience" since 2007
A novel stamped hybrid solar cell was proposed using the stamping transfer technique by
stamping an active PEDOT:PSS thin layer onto the top of silicon nanowires (SiNWs).
Compared to a bulk-type counterpart that fully embeds SiNWs inside PEDOT:PSS, an
increase in the photovoltaic efficiency was observed by a factor of 4.6, along with
improvements in both electrical and optical responses for the stamped hybrid cell. Such
improvements for hybrid cells was due to the formation of well-connected and linearly aligned
active PEDOT:PSS channels at the top ends of the nanowires after the stamping process.
These stamped channels facilitated not only to improve the charge transport, light absorption,
but also to decrease the free carriers as well as exciton recombination losses for stamped
hybrid solar cell
