INL researchers innovating in next-generation solar power

Solar cells, also known as photovoltaic cells, directly convert sunlight into electricity. The most prevalent type, crystalline silicon photovoltaic cells, found in commercially available solar panels, benefit from extensive expertise and synergies with the microelectronics industry. Despite their cost competitiveness, silicon photovoltaic cells have limitations, such as poor sensitivity to low light, rigid modules, conservative aesthetics, and limited flexibility in dimensions. If photovoltaics are to be deployed in a larger number of applications, these limitations need to be addressed. The Nanofabrication, Optoelectronics, and Energy Applications (NOA) research group is exploring novel thin-film solar cell concepts – or next-generation photovoltaics – to enhance performance while meeting environmental standards. They are particularly focused on developing solutions that merge conversion efficiency, durability, and aesthetics for building-integrated photovoltaics (BIPV), targeting stakeholders in the construction industry. BIPV offers a practical means of integrating photovoltaic systems into buildings, potentially facilitating the installation of hundreds of gigawatts worldwide without the need for additional land. This approach aligns well with the current trend of urbanisation. Pedro Salomé, NOA’s group leader, elaborates “We are engaged in various projects, funded by Portuguese and European programmes, to devise solutions that overcome the challenges posed by conventional silicon modules. Most of our […]

A microfluidic platform that simulates human digestion

In a recently published study, INL researchers developed an innovative microfluidic platform that is capable of replicating key human gastrointestinal processes, offering a game-changing tool for the assessment of newly-developed drugs and/or food supplements. The innovation combines a ‘Digestion-Chip’ and a ‘Gut-Chip’, each enabling sequentially the simulation of digestion through the gastrointestinal tract and the evaluation of intestinal permeability. The study ‘From mouth to gut: microfluidic in vitro simulation of human gastro-intestinal digestion and intestinal permeability’, introduces a miniaturised setup that allows studies of sample bioaccessibility and simplified bioavailability using minimal sample amounts. In addition, the outflow from the ‘Digestion-chip’ can be exposed to the cell-based Gut-Chip, which replicates the intestinal epithelium, using unprecedentedly low sample dilutions thus allowing the detection of ‘rare’ compounds. Both devices work in continuous flow requiring very little user interfacing. In this work, casein – a milk protein that is widely used as a supplement in sports nutrition – was tested as a model compound. And critically, the Gut-Chip can be used to evaluate intestinal permeability offering reference permeability values that are in line to those found using human ex vivo models. Miguel Xavier, one of the first authors of the research study adds “the […]

12th SciComPt Congress in Braga

In the pursuit of an inclusive scientific landscape, the 12th Congress of the SciComPt network will convene between May 8-10, 2024, in Braga, Portugal. Themed “Accessibility in Science Through Diverse Languages and Voices”, this landmark event aims to address the pressing need for enhanced accessibility in science communication. In today’s society, the responsibility of science extends beyond the laboratory walls. Merely providing access to scientific publications falls short of empowering citizens to fully engage with scientific knowledge.
