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 group main focus is the incorporation of nanotechnology in optoelectronic devices. For this end, several international collaborations are on-going and these ensure 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. While the nanofabrication relies on INL´s state-of-the-art clean room facilities, the characterization counts on the vast experience of the group members in semiconductor materials. The conjugation of both competences allows us to collaborate with both industrial and academic partners in: developing novel technology, prototyping, validating fabrication processes, products, among others.

PROJECTS

Advanced aRchitectures for ultra-thin high-efficiency CIGS solar cells with high Manufacturability, or ARCIGS-M, 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.

The project is working on thin film solar cells based on Cu(In,Ga)Se2, or CIGS, because this technology is low weight, low light efficienct, flexibile, has great aesthetics, and has reasonable and competitive production costs. Ultimately, the project main goal is to lower CIGS solar modules production costs to even lower numbers. The group objective in the projects is to 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. In the group we are using dielectric structures to incorporate photonic concepts into the solar cells.

Chalcopyrite 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.

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.
