Proceedings of 6th International Conference on Hybrid and Organic Photovoltaics (HOPV14)
Publication date: 1st March 2014
Recently, solar cells composed of perovskite compounds as absorbers attract great attention. Impressive performance was achieved not only in solid state dye sensitized solar cells,1,2but low-temperature processed organic solar cells.3 We started employing CH3NH3PbI3 in organic solar cells very recently. The progress is encouraging. Here we will present our preliminary results of solar cells based on CH3NH3PbI3.
There are several different ways to prepare or synthsize perovskite compounds. We use a two-step approach developed very recently by the Yang group.3 Photocurrent of 19 mA/cm2 was achieved with the device structure of ITO/PEDOT-PSS/ CH3NH3PbI3 /PC71BM/Al (black curve in Figure 1a). The small fill factor (FF), Voc and large dark current (Figure 1b) indicate that the efficiency of the device was mainly limited by leakage current. To prevent leakage current, a small amount of polymer (P3HT) (5%) was added into the electron-transportlayer (ETL) PC71BM. Significant improvement of FF and enlarged Voc was observed. The I-V characteristics of the solar cell suggest that the leakage current was effectively suppressed and the efficiency went up to 6% as shown in Table 1), even though the photocurrent dropped to 13 mA/cm2(red line in Figure 1a)

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.
