Optimizing the interface between the perovskite and transport layers, and modifying electron transport layer (ETL) are critical for enhancing the performance of perovskite solar cells. Herein, we introduced three conjugated polymers (DPPF-BDD, DPPT-BDD and DPPSe-BDD) as antisolvent additive and ETL blending. After polymer treated, PSCs displayed maximum PCE of 23.48%, 22.85% and 23.35%, respectively, surpassing the control device (22.83%), which was benefited from the perovskite near-infrared (NIR) region absorption[1], surface passivation and the electron transport layer (ETL) charge extraction improvement. Finally, we performed the long-term stability test for DPPF-BDD, DPPT-BDD and DPPSe-BDD based PSCs stability at 85oC in glovebox. The control device degraded to 39.8% of its initial PCE after 240 h. The DPPF-BDD, DPPT-BDD and DPPSe-BDD treated devices still remained 74.8%, 57.6% and 43.0% of the initial PCE after 430 h respectively. The stability improvement is attributed to the passivation effect, which effectively smoothed perovskite surface and reduced defects.
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.
