Atomic force microscopy (AFM) is a microscopy widely used for surface analysis of films, particularly organic films such as polymers and very thin films such as graphene films. The Kelvin probe force microscopy is a variant of the AFM and very important for analysing areas with different potentials on the film surface, allowing the location of regions of higher or lower electron density. …
The system for photoelectrochemical measurements can investigate the photoelectrochemical properties of solar cells and electrodes containing photocatalysts. The equipment comprises a potentiostat/galvanostat with an integrated LED driver, a sensor and a set of LEDs. The available measurements include determination of current-potential curves (determination of short-circuit current, open …
The Dense Energy Carrier Division will consolidate expertise in materials processing, advanced characterization and physics of semiconductors devices of LNNano/CNPEM with that of Universidade Estadual de Campinas (UNICAMP), Universidade Federal do ABC (UFABC) and Universidade Federal de São Carlos (UFSCar) in electrochemistry and photoelectrochemestry to develop state-of-the-art research…
Increasing global energy demand and environmental concerns have prompted the development of renewable energy technologies. Photovoltaic (PV) technology has become explosively popular because it can convert vast amounts of solar energy into electrical energy. However, to achieve further spread in the future, new materials different from the currently popular silicon that can be used for li…
Our proposal is to find the most efficient and stable photocatalysts and co-catalysts for selective glycerol oxidation to DHA using a photoelectrochemical cell (PCE) system. Understanding of the oxidation reaction, its mechanism and kinetics are also the focus of this proposal using techniques, which are complementary from both Institutions. Glycerol is a sub-production from the biodiesel…
Hybrid organic-inorganic perovskites based on CH3NH3Pbl3 are a very promising alternative for manufacturing low-cost PV modules, but improvement in device stability is still required to endure that this emerging material can become a reliable technology. The rapid progress on fabricating high efficiency devices happened much faster than the understanding of the basic chemistry involved on…

This research proposal is inserted in the progressively relevant global context, in which developing new energy technologies to mitigate global warming is a critical issue for an energy-dependent society today. The search for new sustainable energy production and storage technologies becomes essential to solve the problems of energy demand and the depletion of fossil fuels. In this contex…
Solar energy is in the spotlight among the alternative and sustainable sources that can supply the rising energy demand. Among them, Perovskite Solar Cells (PSC) have been gain attention. Part of this interest is due to the historical increase in terms of power conversion efficiency, changing from 3%, in 2009, for more than 25% in 2019. Such a value is bigger than the obtained for the cel…
Hybrid organic-inorganic perovskites have attracted great interest in the field of photovoltaic technology due to their excellent optoelectronic properties, and low-temperature processability. In just a few years, Perovskite Solar Cells (PSCs) reached a Power Conversion Efficiency (PCE) of over 25%. Despite great advances in terms of efficiency, there are still challenges that need to be …
Lead halide-based materials, especially perovskites, have been of great interest for applications in optoelectronic devices. What brought such notoriety to perovskites was the rapid increase in efficiency of photovoltaic devices whose active layers are made of these materials. As a result, analogue materials have become equally important.However, among the vast collection of works publish…
The Photoconversion Efficiency (PCE) of solar cells containing hybrid perovskites, using organic cations such as formamidinium and cesium, has approached the 25.6% mark, reaching an important milestone of being close to the commercially available silicon cell. However, the stability of these devices is still not suited for commercial application as they still present degradation facing en…

In only a decade, the lab-scale perovskite solar cells (PSCs) achieved a record efficiency of 25.7% the fastest advance in photovoltaic technology in History. However, despite the rapid progress of efficiency, some challenges remain to be solved to speed up the commercialization of these devices. The main challenges include performance loss and low stability under environmental conditions…
Metal halide perovskites (MHP), with the chemical formula ABX3 (A: monovalent organic or inorganic cation, B: divalent metal, and X: halide anion) have found application in a range of optoelectronic devices ranging from light-emitting diodes to solar cells, and photodetectors. The use of two-dimensional (2D) perovskite structures in these devices has been demonstrated to exhibit a number …
The photovoltaic research was dramatically changed in the last years by the emerge of the perovskite solar cells. The efficiency of this type of solar cells increased in a fast rate and the currently record (23.3%) have placed this kind of device in competition with others well-established photovoltaic technologies, such as silicon and thin-film. Despite the high efficiency, many aspects …
Cs-based lead perovskites nanocrystals (CsPbX3) will be synthesized in situ in a x-ray beam line from synchrotron source to evaluate their growth from the precursors. The precursors will be dissolved in a vessel and heated. The growth of the nanocrystals will be probed via SAXS and WAXS. The purpose is to elucidate the growth mechanism of these nanocrystals, a pioneer work in the literatu…
