DESCRIPTION

NOA

Wire Grid Polarizer fabricated at INL´s state-of-the-art clean room as a service for an industrial client with NOA´s help.

Founded in early 2017, the Nanofabrication for optoelectronic applications – NOA- group focus in the incorporation of nanotechnology in optoelectronic devices. While our technological development is made in-house using INL’s state-of-the-art nanofabrication processes, several international collaborations are on-going ensuring that our technology is incorporated in ultramodern and industrially relevant devices. The core competences of the group are bottom-up nanofabrication and characterization of optoelectronic materials and devices. NOA´s nanofabrication cornerstone is INL´s cutting edge clean room facilities and the vast experience of the group members in semiconductor materials is the backbone of the characterization capacities. The conjugation of these both competences are the stepping stones that allows us to collaborate with both industrial and academic partners in: developing novel technology, prototyping, validating fabrication processes, products, among others.

The overall goals of the group are:

  • To develop of new optoelectronic device concepts that incorporate nanotechnology with IP potential.
  • To explore industrial-friendly nanofabrication concepts that can be used to enhance the performance of optoelectronic devices.
  • To identify limitations of optoelectronic devices and search for solutions and novel materials.

NOA´s strategy:

  • To be fully capable of prototyping and developing technology into real-life devices for 1) sensors, energy harvesting, IoT applications; and 2) building integrated photovoltaics (BIPV).
  • To develop a vast know-how of large-area nanofabrication techniques appealing to industrial partners.

RESEARCH LINES

Focusing on chalcopyrite solar cells, NOA is creating novel concepts for solar cells architectures that allow for ultrathin absorber layers to be used, hence, lowering production costs and increasing light to power conversion efficiency. In this area we include nanofabrication for passivation of interfaces and light trapping arrangements including photonic structures.

  • Advanced aRchitectures for ultra-thin high-efficiency CIGS solar cells with high Manufacturability – ARCIGS-M (H2020 action number 720887
  • Novel Architectures For Improved thin film Solar Sells –NAFISC- (FCT action number IF/00133/2015)
  • Development of novel Ultrathin solar cell architectures for low-light, low-cost and flexible opto-electronic devices-NovaCell – (FEDER action number 28075)

NOA - advanced materials interface

Chalcogenide semiconductors have superb properties for optoelectronic applications, however any change made into a semiconductor has deep impacts in the device where it is incorporated and the resulting effects need to be fully characterized. We use several electrical, optical, and microscopy techniques to characterize novel and cutting edge optoelectronical materials. With a focus on chalcopyrite and kesterite materials, we also study other new materials like Sn(S,Se); Sb2(S,Se)3, etc.

  • Development of innovative nanostructured dielectric materials for interface passivation in thin film solar cells – InovSolarCells – (FEDER action number 28075)
  • PhD Grant – PD/BD/142780/2018

At NOA we value education and we support students by hosting internships, master thesis and PhD thesis. The group students benefit from INL’s outstanding facilities, diverse cultural environment and the experience of the group in hosting and supervising young and bright minds. Typically, NOA students are authors in papers and patents, participate in international projects, achieve stellar marks in their reports, ensuring that they have both excellent training but also results and soft skills necessary for their academic or industry future. We also provide post-studies support by connecting the students with our industrial and academic partners. Contact Pedro or Paulo for more information.
