Future-generation solar cells are continually being introduced and
refined. These new designs, however, are often based on new
materials and there is a lack of fundamental understanding about
how such devices work and how they can be improved. Conjugated
polymers and small molecules are two such promising classes of
materials suited for use in low-cost, thin-film solar cells. The
performance of these materials, however, is highly dependent on
film structure, and directly correlating local film structures with
device performance remains challenging. This work describes several
new techniques developed to probe and control the local
optoelectronic properties of organic semiconducting films. These
techniques include electrostatic force microscopy (trEFM),
photoconductive atomic force microscopy (pcAFM), and a fabrication
technique based on Dip-Pen Nanolithography (DPN). Taken together,
these methods provide a first nanoscale look a charge and current
generation in organic photovoltaic films. This work introduces
these new techniques for the reader and details how they are being
used to solve current scientific questions.
