Tin perovskite solar cells (Sn-PVK PVs) have attracted attention as Pb free PVK PVs having the band gap of about 1.3-1.4 eV, which is the best band gap from the viewpoint of Shockley-Queisser limit. One of the alloyed perovskites, Tin Lead perovskite solar cells (SnPb-PVK PV) is a candidate as the bottom layer of the perovskite tandem solar cells(1). We have reported Ge ion doped Sn-PVK solar cells with the efficiency higher than 14% and SnPb alloyed perovskite solar cells with the efficiency higher than 23%. In this talk, we discuss these high efficiencies from the viewpoint of modified hole transport layers. In almost all Sn-PVK PVs, PEDOT-PSS has been employed. We now report the SnOx (x=1.77) as the hole transporting layer. The normal structure with SnOx layer working as ETL did not give sufficiency efficiency which has been already reported by us(2). However, the inverted structure consisting of SnOx working as the hole transporting layer gave the efficiency of 14. 1%(ACS Energy Letters, accepted). The mechanism is discussed in detail. In addition, we report SnPb-PVK PV with 23.3 % efficiency by using mixed 2PACz/methylphosphonic acid hole transport layer, where we aimed at enhanced surface coverage on FTO by mixing small and large phosphonic acids(3).
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.
