| Summary: | Organic photovoltaic (OPV) materials provide a promising path in the search for sustainable
energy solutions because of their potential for high efficiency and flexible application. This
work explores the photoactive layer of OPV cells, with particular attention to the binary
mixture of Y6 as a non-fullerene acceptor (NFA) and PM6 as a donor. We investigate how
different PM6:Y6 ratios affect thin film morphology and photovoltaic characteristics. We
explore the optical properties and surface morphology of the films by a series of studies using
techniques including UV-Vis characterisation, Scanning Electron Microscopy (SEM), and
Grazing Incidence Small & Wide Angle X-ray Scattering (GISAXS & GIWAXS). The results
seek to maximize the donor-acceptor ratio to enhance structural characteristics and maybe
increase the performance of OPV cells. These results contribute to the ongoing evolution of
solar cell technology, signifying a step forward in achieving more efficient and stable
renewable energy sources. |
