Optical characterization of P3HT: PCBM (poly (3-hexylthiophene-2,5-diyl)): ([6,6] -phenyl C61 methyl ester of butyric acid) and PEDOT: PSS (layers of poly (3,4-ethylenedioxythiophene) ))) thin films deposited using the Spin Coating technique were studied using an effective medium approximation method (EMA). This method involves transmittance, reflectance and absorbance measurements, which describe the changes in their optical properties depending on the compositional balance of the materials involved.
The optical results were compared with the electrical characterization of each of by separated, and also has been performed for the Organic solar cells based on P3HT:PCBM deposited on ITO substrate by means the I-V characterization.
The results obtained on the organic solar cells shows a dark current density of 1.28 mA/cm2, a fill factor FF of 0.65 and a conversion efficiency of 1.01% for P3HT:PCBM solar cell.The perspective is improve the efficiency of organic solar cells by texturing techniques and nano-particles (colloidal crystal inside the active layer).

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
