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.

NOA´s long term goals are:

  • 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.

PROJECTS

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.

On this topic we have two external projects ongoing.

1-Advanced aRchitectures for ultra-thin high-efficiency CIGS solar cells with high Manufacturability (ARCIGS-M action number 720887) is an H2020 funded project coordinated by the University of Uppsala. The project gathers thirteen institutions aiming to work on lowering the production cost of thin-film solar cells by developing advanced solar cell architectures.

More information at https://www.arcigs-m.eu/

2- Novel Architectures For Improved thin film Solar Sells (NAFISC), an FCT investigator project (IF/00133/2015). The development of optical structures that increase light trapping by introducing light management strategies into solar cells are highly interesting since they can increase both the electrical performance and can lower material costs.

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.

PROJECTS

Electrical losses due to interface junctions in state-of-the-art thin film solar cells are not fully minimized. In this project we use cutting edge nanotechnology to create a point contact structure that lowers the interface recombination of solar cells.

The development of optical structures that increase light trapping by introducing light management strategies into solar cells are highly interesting since they can increase both the electrical performance and can lower material costs. At NOA we are using dielectric structures to incorporate photonic concepts into the solar cells.

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 opto-electronical materials.
