To meet the growing global demand for clean energy sources, significant efforts have been made to seek affordable and sustainable alternative sources of renewable energy with less environmental impact. In this context, perovskite solar cells (CSP) based on organic-inorganic hybrid compounds of lead halide such as CH3NH3PbI3, have become one of the most promising photovoltaic technologies,…
Based on our previous experience, we propose a step forward in materials science research with the formation of a multidisciplinary Center for the Development of Functional Materials (CDFM). This center will be an offshoot of the Multidisciplinary Center for the Development of Ceramic Materials (MCDCM) which received FAPESP support from the first version of the CEPID program. The core foc…
The activities of Prof. Franco Decker will be in the field of solar cells, more specifically on dye sensitized solar cells. He is an experienced researcher with a number of well recognized research articles. One important aspect is that Prof. Decker speaks Portuguese, which shall facilitate his interaction with different students. His research plans shall be on the following themes: fabri…
In the present proposal three different sensors are developed which are especially useful to physicians as well as to biomedical researchers. In the first, the goal is to make a dosimeter based on the ionizing radiation induced modifications in the electronic properties of conjugated polymers, with special emphasis on poly (piphenilenevinilene). In this sub-project the new dosimeter is pr…

The advent of perovskite solar cells based on hybrid lead halide excited the photovoltaic community due to the efficient conversion of sunlight into electricity that already reached 25%. The unprecedented progress within a very short time and a notable performance and easy processability opened a new era in optoelectronic technologies. Although, there are instabilities in humidity conditi…
The development of electronic devices from naturally derived materials is of enormous scientific interest. Melanin, a natural pigment composed of different structural subunits; may be particularly valuable due to their inherent biocompatibility and for being a hybrid conductor. However, the low conductivity of melanin limits the development of bioelectronic devices. In this project, elect…
The present project aims to obtain and characterize organic electrochemical transistors (OECTs) from synthetic melanin in combination with conductive materials. The OECT is a device capable of modulating the current of a semiconductor channel by changing its doping state through gate-controlled ion injection. The device arouses great interest due to its ability to emulate synapses and pot…

Records show that in 2009 the efficiency of photoelectric conversion (PCE) of solar cells using Perovskites (PSCs) was 3.8% and nowadays it reaches 25.2%. In addition to being highly efficient, Perovskites (PVK) can be prepared with low-cost materials and techniques, making them an excellent technology to be commercialized. However, PSCs face long-term instability problems under realisti…
The growing demand for electricity has led man to consume more and more the planet's natural reserves. In view of this, new sustainable ways of producing electricity have been studied, among them, the most promising is solar energy, which, converted by a solar cell (CS) through the photovoltaic effect, it generates electrical energy. Currently, of the technologies applied in CSs, those co…
Nowadays perovskite solar cells are one of the most promising technologies for the generation of clean and renewable energy due to its high efficiency in convert solar to electric energy, more than 23%. Despite their high efficiency, these devices show low stability due to its components, for instance, the TiO2 electron transport layer. TiO2 has been shown to be prejudicial to the device …

Organic bioelectronics is an interdisciplinary field that is growing at a fast pace. The field promises new methods for detecting, reading or writing biological signals with organic electronic devices to enhance medical outcomes. A key research focus in bioelectronics is investigating methods for transducing a signal from biological media (predominantly due to ions and protons) to modern …
Bioelectronics is an area with remarkable scientific and technological interest due to its vision to relate electronic and biological systems. Currently, one of the phenomena being studied is proton transport in natural materials. Devices based on hybrid protonic and electronic transport are also explored. In these devices, the hybrid behaviour of the transport as a function of the relati…
