Power Roll are recruiting! 

23 February 2021

Power Roll, a developer of a game-changing, ultra-low-cost and lightweight flexible film for energy generation and storage, are looking to recruit a Perovskite Research Scientist to join their team.  

Please see below the job description and requirements for the Perovskite Research Scientist role, if you feel you are suitable please email your CV to info@powerroll.solar (no agencies please).


Research Scientist "Development of flexible perovskite solar cells from Roll-to-Roll (R2R) technology” 

Power Roll Limited (“PRL”) has developed a new and unique platform architecture that uses microgroove structures to create a variety of two terminal electrical devices. The two current primary areas of focus for PRL at present are in the fields of energy storage and solar photovoltaics (PV). Both technologies are enabled by the unique and patented microgroove technology invented by Dr John Topping, PRL’s Chief Scientist. The micro-groove architecture enables energy storage and PV technologies to be manufactured using low-cost roll-to-roll (R2R) processes already deployed in other sectors such as food packaging and holographics and removes many of the process steps required by existing technologies. 

PRL have proven its solar technology in 20cm2 modules, which contain over 8000 individual solar cells. It’s objective now is to build a pilot facility in the North East, and scale the technology. PRL work with world leading research partners to help bring this new innovative technology to market. 

The position will be connected to the Roll-to-Roll (R2R) facility, where the successful candidate will be working on Sheet-to-Sheet (S2S) and Roll-to-Roll (R2R) printing of perovskite absorber materials for perovskite solar cells (PSC). 

The candidate will work on perovskite ink formulation tailored to R2R and large area S2S printing, as well as the development of the printing processes, which will primarily focus slot die coating.  Device characterisation will also be a key part of the candidate’s role. 


Perovskite ink formulation and characterisation: 

  • Develop perovskite ink formulations for R2R/ large area S2S deposition tailored to PRL’s microgroove architecture 

  • Work with external partners to scale up ink synthesis 

  • Characterisation of perovskite inks and PCSs 

  • Data analysis and reporting 

  • Keep up to date with relevant scientific literature 

  • Prepare and implement relevant H&S documentation (COSHH assessments) 

  • Good laboratory practice 

R2R printing and large area S2S printing: 

  • Develop ink printing processes for R2R/ large area S2S deposition tailored to PRL’s microgroove architecture, focussing on, but not limited to slot die coating 

  • Operation of printing equipment 

  • Create process documentation including work instructions and procedures 

  • Prepare and implement relevant H&S documentation (risk assessments) 

  • Good laboratory practice 


  • PhD (or >2 year post-doctoral position) focussing on perovskites inks for PSC devices 

  • Bachelor’s degree in related discipline - Physical Sciences/ Engineering 

  • >3 years chemical laboratory experience 


  • R2R or large area S2S experience, preferably printing perovskites for PSCs 

  • Understanding and practical experience with a broad range of characterisation techniques. Including, but not limited to: PV device testing beyond JV measurements, optical microscopy, UV-Vis spectroscopy, XPS 

  • Demonstrable experience with experiment design and data analysis 


About Power Roll

Power Roll, headquartered in Sunderland, has developed a unique, flexible, lightweight solar film capable of producing ultra-low-cost green electricity that is up to 20 times cheaper to make than existing flexible PV. By applying different coatings to its versatile microgroove design, Power Roll can also use the film for energy storage and to manufacture capacitors. Power Roll’s microgroove film is suitable for non-load-bearing rooftops, building integration, transport, portable applications, off-grid projects and IoT sensors.
