This thesis is divided in three parts. The first one deals with the synthesis of polyaniline (PANI), a hole conducting polymer, used in many applications. By varying the quantities of the monomer and the oxidant while fixing the molar ratio at 1:1.25, and by adding magnesium oxide, novel echinoid-like and PANI needles were formed. The formation mechanism of the 1D structures is explained using the multi-layer theory. The second section is devoted for the fabrication of low cost single-layered photovoltaic devices based on the working principle of dye-sensitized solar cells (DSSCs). In 1991, Grätzel reintroduced the photo-electrochemical effect by developing the first DSSC, one of the third generation solar cells, formed of a TiO2 film (phot...
