Developing new energy sources is one of the most urgent issues for the whole world, as fossil fuels will be exhausted shortly. Solar energy is a clean, free of cost, sustainable and abundant energy source, harvesting just a small fraction of available solar energy would be enough to satisfy the world's entire energy demand. Impressively, low-cost solution-processed lead halide perovskites…
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,…

Until recently, poly(fullerene)s (PFs) have been considered a purely academic subject with little relevance to applications. In the last year, publications in very high impact journals have demonstrated that these materials, which carry fullerene in the main-chain, can be used to great effect to both stabilize and improve efficiencies of perovskite solar cells and organic solar cells. The…

Perovskite solar cells (PSCs) are among the most promising emerging photovoltaictechnologies due to their superior optoelectronic properties and low-cost, solution-basedprocessing. Their power conversion efficiency has risen from 3.8% to over 26% in the past15 years. At this stage, advanced diagnostic techniques are crucial to assess device stabilityand support their future commercializat…
This project aims to explore the use of melanin as a passivation layer in perovskite solar cells (PSCs) to address critical challenges such as stability, defect passivation, and moisture resistance. Melanin's unique properties, including its active functional groups (C=O, C-OH, COOH, N-H, S=O, S-CH3), chelation capabilities, and hydrophobic sulfonated groups, make it an excellent candidat…
Perovskite solar cells (CSPs) based on organic-inorganic hybrids compounds such as CH3NH3PbI3 have become one of the most promising photovoltaic technologies, as they have shown high photoconversion efficiency (PCE), greater than 25%, and low cost. However, its low stability, mainly in the presence of humidity is a barrier to its commercialization. So, the searcher for materials with supe…

The present project intends to study the electrical properties of melanin films seeking a better understanding of the conduction mechanisms of the material, enabling its use in bioelectronics. The interest in melanin in this area is linked to its biocompatibility and proton conduction characteristics related to the hydroxyl (OH) and carboxyl (COOH) functional groups in its composition, al…
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.
