Synthesis and characterization of indeno[1,2-b]fluorene-based low bandgap copolymers for photovoltaic cells

Titanium oxide TiOx material is used as electron transporter in organic photovoltaic cells (OPV). The layer was prepared between P3HT:PCBM as the active layer and the and aluminum electrode by spin coating technique. The synthesis and characterization of TiOx is described. Using Raman spectroscopy technique TiOx crystals show anatase structure. Varied concentrations of TiOx and isopropanol solvent were performed. The most optimized device efficiencies up to 2,0% was achieved at a 1:20 ratio, which indicated more than 50% efficiency enhancement comparing with the device without TiOx layer. The major improvement of the cell was originated from photocurrent enhancement.

Precursor Composition

Hybrid perovskite is one of the emerging materials which is currently being widely investigated for solar cells. Here we report the synthesis and characterization of perovskite compound which can be used as a light harvester in photovoltaic cells, which is CH3NH3PbI(3-x)Clx. The perovskite materials were synthesized using solution-based methods. Several parameters are investigated in the synthesis of CH3NH3PbI(3-x)Clx perovskite, which are the influence of precursor composition, synthesis temperature , precursor concentration, and the annealing temperature. These parameters are optimized against the absorbance and bandgap of the synthesized CH3NH3PbI(3-x)Clx thin film. The optimized perovskite thin film is obtained with excellent absorption capabilities for solar cell applications.
