The Department of Applied Physics (http://physics.aalto.fi) at the School of Science is seeking a
Postdoctoral Researcher in textile photonics for solar energy
Combining expertise in photovoltaics and textile design, an interdisciplinary research team at Aalto University has developed an efficient, durable, and aesthetic concept for integrating solar cells with textiles to provide energy autonomous operation for wearable electronics and smart textile applications. We now seek a postdoc researcher to join the team to carry out challenging applied textile photonics research aimed at developing a revolutionary, commercially feasible, solar cell textile technology. The research carried out in a two-year Co-Innovation project funded by Business Finland (Sun-Powered Textiles, 2019 - 2021) involves close interdisciplinary collaboration with textile design researchers and the Finish textile and electronics industry.
Batteries currently used as power source in textile electronics limit the scope of smart textile applications due to issues with cost, reliability, usability, and environmental sustainability. Harvesting energy from sunlight solar cells could provide smart textiles with energy autonomous operation, but their integration with textiles requires that both the energetic and aesthetic performance, in addition to other technical properties, match the end-use needs. The Sun-Powered Textiles project addresses this challenge by combining solar cell and textile photonics research with textile design and engineering, textile manufacturing, prototyping, testing, and market research.
Your role and goals
As our newest team member, you will work together with physicists and textile design researchers from Aalto University and with textile and electrical engineers from the partner companies to develop novel textile materials and structures for integrating solar cells with textiles. The challenge is to efficiently couple incoming sunlight to the photovoltaic elements while preserving good visual aesthetics of the overall design. You will perform pioneering, application-oriented, scientific research on solar cell textile photonics, including:
- Optical characterization of textile materials with spectroscopic, colorimetric and imaging techniques.
- Optical and photovoltaic design and performance analysis of textile solar cells prototypes.
- Optical modelling for explaining how textile material properties and design parameters affect the photovoltaic and aesthetic performance, and translating it to practical figures-of-merit for textile testing.
- Development of innovative solutions for textile solar cell by merging physics and design insights.
- Guiding of a master’s thesis project on the estimation of the energy generation potential of textile solar cells at different end-use conditions for energy autonomous textile electronics.
Your results will direct the development of textile solar cell prototypes fabricated in the project and provide scientific background for establishing design guidelines for textile engineers and designers. In this role, you will actively interact with and provide input to other project researchers working on solar textile design, testing and prototyping. You will also organize the work of the project consortium partners related to the above-listed topics using university resources and administrative support. As a senior team member, we expect you to leverage the project to develop new research ideas and questions and have the freedom to explore them.
The position is situated in the New Energy Technologies group in the Department of Applied Physics (School of Science) and involves close collaboration between the Fashion/Textiles Futures research group of the Department of Design (School of Arts and Design). The interdisciplinary research team dedicated to this project includes a postdoctoral researcher (this position), a master’s thesis worker, and a research assistant in the Department of Applied Physics; and a postdoctoral researcher, a designer in residence, and two master thesis workers in the Department of Design. The team aims for high-quality scientific publications and commercialization of the research results. We have service members in both Schools who will work with you to support publications and commercialization success.
The physics team lead Dr. Janne Halme has expertise in solar cell device physics, printed solar cells, optical modelling and characterization, and solar cell durability studies. His team’s current focus is on new photonic approaches for efficient, coloured photovoltaics for building- and product-integration. The New Energy Technologies group has fully equipped solar cell characterization and accelerated aging labs, and access to high-quality spectroscopy and microscopy facilities in the Department of Applied Physics and through the OtaNano research infrastructure.
The textile team lead Dr. Elina Ilén is D.Sc. (Tech) in fibre materials, and has long experience and deep interests to R&D of wearable textile electronics and functional clothing innovations. The Fashion/Textile Futures group explores new perspectives on human-centred design research with focus on sustainable fashion and textiles. The group members’ research activities include material-based research, aesthetics and creativity studies, practice-based research, and strategic fashion and textile management.
The Sun-Powered Textiles consortium also includes three companies with parallel R&D projects: Foxa (high-performance textiles for clothing industry), Lindström (professional clothing and textile services) and Haltian (electronics solutions for wearables and Internet-of-Things).
