Organic photovoltaics have the capability to overcome to their inorganic counterparts due to several reasons like low weight, flexibility and low price. Transient Absorption Spectroscopy (TAS) represents the perfect tool to study this kind of devices. TAS is a pump-probe technique, with two different light sources: one excites the sample whereas the other probes the photogenerated excited states. This way, with TAS, we are able to follow the different processes taking place in organic photovoltaics, from charge photogeneration to the different efficiency loss pathways.
In this work two different systems are presented where unexpected behaviour is obtained. In the first case, DRCN5T is studied. DRCN5T is a well extended material used in binary and ternary solar cells as small molecule donor. In our work, how this molecules is able to generate a large number of triplets is demonstrated, despite being able to obtain large efficencies. In addition, the annealing process is shown that largely increases the number of triplets generated in this material.
The second family to be studied is a range of NDI materials where some substituents is systematically changed in order to stablish a difference between the orthogonality between the core and the substituent. With the help of TAS, it is shown how the orthogonality is associated with an enhancement in the charge generation for these materials.
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.
