Perovskite photovoltaics offer a low-cost, high-efficiency solution to speed up the transition to net-zero emissions. In particular, tin-lead perovskite solar cells have ideal optical properties for peak performance. However, their large-scale use is hampered by stability issues at perovskite surfaces, i.e., oxidation, vulnerable defects, and chemical mismatch with ordinary charge transport layers in solar cells. Self-assembled monolayers (SAMs) are alternative transport layers that allow the manipulation of critical interface regions, yet their use in tin-lead perovskite photovoltaics remains in its infancy. Careful choice of SAM functional groups, molecular structure and redox chemistry are key to tackle perovskite limitations. SAMper will develop ultrastable and highly efficient tin-lead perovskite solar cells by designing SAM device architectures with interface-specific smart functionality. Defect-passivating, perovskite-healing and oxidant scavenging SAM moieties will afford the targeted properties, as will be demonstrated via structural, chemical and electrical interface analysis. Top SAM-based devices will be tested outdoors to demonstrate their excellent durability and efficiency, comprising the first example of tin-lead perovskite solar cell testing under real-world conditions and paving the way towards their commercial deployment. SAMper contributes towards clean energy in alignment with European Green Deal decarbonisation targets. The project will further the researcher's excellence and career prospects via training on cutting-edge multidisciplinary research. Knowledge transfer with the supervisor will foster the researcher's scientific independence via key management skills. The secondment for outdoor tests will facilitate international synergies. Project outputs and datasets will adhere to FAIR principles, aiding the benchmarking of the technologies herein. Various activities will disseminate these results, and foster STEM vocations among local youth.

The World's digital transformation generates vast amounts of data daily. Conventional computing technologies face serious challenges in efficiently handling all this information, leading to high energy consumption. Neuromorphic computing offers a more efficient solution by designing systems inspired by the structure and function of the human brain, which processes information in parallel with minimal energy consumption. A key component in this technology is the memristor, a novel electronic element that mimics the synapses and spiking processes of neurons. The memristors containing lead-based halide perovskites (Pb-HPs) are among the best-performing, but the presence of toxic Pb hinders their practical application. MemSusPer aims to develop sustainable, Pb-free HP memristor devices with high performance, stability, reproducibility, and low energy consumption. This will be achieved through two main strategies: (1) enhancing the quality of the perovskite films, and (2) using novel buffer layer materials, such as organic mixed ionic electronic conductors, to regulate the ions migration and induce new energy-efficient activation/deactivation mechanisms. I will conduct the research at the Institute of Advanced Materials (University Jaume I, Spain) with the guidance of Prof. Antonio Guerrero, a leading expert in the field. To validate the developed technology, a 4x4 memristor array will be fabricated using the advanced infrastructure of the Institute of Emerging Technologies (Hellenic Mediterranean University, Greece). MemSusPer is committed to advancing next-generation neuromorphic computing, which is not only high-performing but also eco-friendly, contributing to the green and digital transitions prioritised in the European Union's agenda. The multidisciplinarity and high impact of MemSusPer, combined with the training component of the MSCA-PF, will help me become a tenured independent researcher, expand my expertise, and strengthen my academic profile and networks.

Photovoltaic conversion has the extraordinary property of transforming the solar energy directly into electric power. However, the available electrical power is known to be severely limited by the so-called Shockley-Queisser (SQ) photoconversion limit. The maximum efficiency for a single absorber is limited as photons with energy lower than the bandgap (BG) cannot be absorbed, and just an energy equivalent to the BG can be used for photons with higher energy than the BG, due to thermalization. Tandem cells have overcome this SQ limit upon exploiting complex and expensive configurations. Alternative approaches, even with higher potentiality, as Intermediate Bandgap Solar Cells (IBSCs) have not reached the expected performance mainly due to the limitations introduced by the monocrystalline matrix. The incorporation of quantum dots (QD) to create the IB produces layer strain and defects that limit the cell performance. No-LIMIT proposes to revamp IBSCs concept, using polycrystalline halide perovskites (HP) host matrix in order to take benefit from the strain relaxation at polycrystalline materials and from HP benign defect physics. HPs show an outstanding performance even when they are grown in a porous structure, indicating that their excellent transport and recombination properties are preserved with embedded materials. No-LIMIT will exploit this potentiality by using the states of embedded QD as IB in IBSC with HP matrix. The project will focus on the preparation of HPs-QD systems with enhanced light collection efficiency preserving charge transport, recombination and stability. No-LIMIT will study the properties and interactions of the HP and QD materials developed, as well as injection, recombination and transport properties in the coupled system. The combination of these strategies will build a ground-breaking synergistic system able to break the SQ limit. The achievements of IBSC, together with the intermediate steps, will have a colossal impact on photovoltaics

CO2 is the most abundant renewable carbon source in nature and considerate the major greenhouse gas. The development of carbon neutral processes plays a major role against climate change. Despite the large number of recent reports related to CO2 activation strategies, a viable solution with potential industrial applicability is lacking due to the harsh conditions or low productivities. Ideally, the CO2 should be captured and activated under mild conditions of pressure and temperature. The combination of optimal mixing and high throughput offered by flow chemistry and the ability of catalytic structured reactors to transform CO2 under mild conditions, offers great potential to overcome these limitations. Thus, 3D printing (3DP) techniques appears as a versatile method to fabricate catalytic flow devices with scaling up potential, due to their simple, flexible and adaptable features. Polymeric ionic liquids (PILs) emerged as an alternative to fabricate 3D multifunctional structures, with unique, synergistic catalytic and adsorbing abilities. The choice of MATERIAL, REACTOR ARCHITECTURE and the NATURE OF THE CATALYSTS plays an essential role in the efficient CO2 capture and utilization (CCU). 3DPILcat will develop an extremely efficient, configurable, green and scalable protocol for the preparation of TAILORED AND STRUCTURED CATALYTIC DEVICES FOR CCU. The catalysts will be based in PIL co-polymers with CO2-philic moieties, which will capture CO2 at near atmospheric pressure and catalyse the conversion into cyclic carbonates from epoxides and olefins. Combined with a designed architecture obtained from 3DP methodology, the device will act as smart flow reactors highly active, selective and recyclable. The whole body of the structured devices will act as both adsorbent and catalytic agents, employing batch and flow conditions. For the 1st time the PIL, 3DP AND REACTOR ENGINEERING combination applied to CCU will be demonstrated, creating an innovative catalytic product.
