Organic solar cells (OSCs) have shown rapid progress in recent decades. In particular, as the development of electron donor polymers and non-fullerene acceptors accelerated, the power conversion efficiency (PCE) has been improved up to 19%. However, there is a limit to increase the efficiency of OSCs due to the saturation of new materials development. Herein, we improved the efficiency of OSCs by light engineering to enhance the transmission of incident light into the active layer resulting increased photocurrent density. We found that M13 bacteriophages are effective at increasing the light absorption by manipulating sunlight such as an anti-reflection coating layer between ITO and hole transport layer (HTL). To analyze the optical property of M13 bacteriophage layer, transmittance was measured with UV-vis spectroscopy. As a result, the transmittance was increased at 300-400 nm, where donor polymer PM6 has absorption wavelength. Consequently, OSCs employed M13 bacteriophage layer between ITO and HTL showed approximately 13% higher photocurrent density(Jsc). with 23.8mA/cm2 (Jsc), 0.85V (Voc), 0.70 (FF) and 14.1% PCE. These results present the potential of M13 bacteriophage to enhance the efficiency of organic solar cells.
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.
