Proceedings of International Conference on Hybrid and Organic Photovoltaics (HOPV16)
Publication date: 28th March 2016
P3HT:ICBA polymer solar cell system has been extensively investigated in recent year due to its high efficiency, high stability and the ease of raw material synthesis. However, the open circuit voltage (Voc) of single polymer solar cell is usually lower than 1.0V. On the other hand, organic-inorganic metal halide perovskite material exhibits ambipolar property, which can produce voltage under light irradiation. In this work, we modify the P3HT:ICBA solar cell by introducing perovskite layer to enhance the voltage performance of polymer solar cell. In order to conserve energy and broaden the choice of materials for device fabrication, we develop a new non-annealing fabrication process for interconnecting layers, perovskite layer and hole transport layer. Compared with the standard P3HT:ICBA solar cell, the perovskite modified P3HT:ICBA solar cell exhibits significant enhancement in Voc from 0.86V to 1.60V. Furthermore, the stability of the device is maintained, for more than 210 days (5,040 hours) storage, the Voc of the modified solar cell can maintain above 1.55V, which is remarkable for the polymer solar cell to be used in the application of operating small electrical equipment required 1.50V driving voltage.
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.
