Our research interest is the investigation of fundamental processes involved in the conversion of solar energy. For this, we investigate the chemical properties, both in the fundamental state and in the excited state, to understand such processes and, using concepts of advanced material design or molecular engineering, seek to increase their efficiencies. The ongoing investigations in our research group involve nanostructured materials and coordination compounds to improve these functions. We are currently looking to improve systems for converting solar energy into electricity or chemical energy. Thus, we have acted in the understanding of fundamental phenomena that occur in Perovskite Solar Cells; as well as in CO2 Photoreduction processes. (Source: Lattes Curriculum)

Perovskite solar cells (PSCs) are one of the most promising technologies for the future of solar energy conversion. The low-cost and easily processable materials that result in high-efficient devices increase the interest in developing this technology. The most recent Power Conversion Efficiency (PCE) record is 25.7%. Even being a high PCE value, the value is far from the Shockley-Queisse…
The use of fossil fuels for energy generation has been contributing to global warming. Ambiental concerns increased the demand for new clean energy generation technologies. Among several possibilities, the solar light energy conversion Technologies are the most interesting ones due to the use of a clean and unfinishable primary source and several approaches are possible, such as the solar…
Luminescent sensors, light emiting devices, electrical or chemical energy converting systems are usually based on coordination compounds since their properties, such as light absorption, redox potentials and photoreactivity, can be modulated through modification on their structure. These compounds are interesting to be used in the development of direct solar energy conversion into electri…

Ruthenium polypyridyl compounds have chemical, electrochemical and photophysical properties recognized to be used in a wide variety of devices such as luminescent sensors, photoinduced devices and Dye-sensitized Solar Cells (DSSCs). Another device capable of directly convert sunlight into electricity are the organic solar cells and among its components, the use of poly-fullerenes have bee…
Coordination complexes are widely investigated to be applied in luminescent sensors, light-emitting devices, and solar energy conversion systems, in particular, ruthenium(II) coordination compounds have favorable characteristics to perform these functions, such as wide light absorption in the visible region, having excited states with energy levels and lifetimes adequate to participate of…
During the last few years, researches in solar cells are considering a new technology to convert solar energy into electricity. Perovskite Solar Cells (PSCs) have been attracting much attention since it has improved its power conversion efficiency from 4% to more than 20% in just 6 years. The organic-inorganic hybrid perovskites are the most common on this application since they show inte…

Due to its versatility and unique combination of properties, Ru(II) and Re(I) polypyridyl compounds have been widely employed in sunlight conversion systems, such as Dye-Sensitized Solar Cells (DSSCs) or for photocatalytic CO2 reduction. The efficiency of these systems strongly depends on the molecular structure of the coordination compound and the relative rates of each of the several el…
