Printed Photovoltaics: Organic Photovoltaics and Perovskites Research Team

Hind Alsayyed – PhD Student

Hind Alsayyed is a BEng Chemical Engineering graduate from Swansea University. Hind is currently an EngD student sponsored by NSG Pilkington.

Hind’s academic supervisor is Dr Wing Chung Tsoi and her work is focussed on fabrication and characterisation of semi-transparent organic solar cells. Hind’s focus is on the development of semi-transparent top electrodes and active layers using organic materials through solution-processable techniques. 

Areas of Interest

With concerns surrounding fossil fuels, solar technologies are likely to play a key role in future energy generation.

Silicon photovoltaics are currently the most abundant technology. However, organic solar cells (OSCs) may offer several benefits over silicon technologies. These include reduced weight, increased flexibility, reduced costs and compatibility with less energy intensive, low-temperature, high-throughput solution processing. Whilst OSC efficiencies are now approaching the levels of silicon, two key challenges remain: stability and scalability. Andrew’s research aims to tackle these issues by elucidating the causes behind poor device stability and investigating the factors limiting the performance of slot-die coated OSCs.

Areas of Interest

  • Organic photovoltaics 
  • Slot-die coating
  • Multi-spectral mapping
  • Device stability

Ram’s research interests are mainly focused on the development of solution-processable organic solar cells for transparent windows, indoor as well as space applications.

His expertise is on developing organic solar cells based on polymers, and small molecules donors as well as fullerene and non-fullerene acceptors, by using solution-processable methods. Ram has a particular interest in investigating down conversion material (DCMS) to improve the power conversion efficiency, including the stability of solar cells devices.

Dr Datt obtained his PhD in Engineering Science (Thesis Title: “Development of Organic Photovoltaic Devices based on Novel Organic Molecules”) from CSIR- National Physical Laboratory, New Delhi, India under the supervision of Dr Vinay Gupta (SSB Awardee in Physics, 2017). He obtained his Master of Technology (M. Tech, 2013) (nanotechnology) and Bachelor of Engineering (BE, 2011) (Electronics and communication) degrees from School of Nanotechnology, RGPV Bhopal and RJIT Tekanpur, Gwalior, India, respectively.

Areas of Interest

  • Organic solar cells for indoor and space application
  • Down conversion materials

Declan Hughes – PhD Student

Declan is a PhD student under the guide of Dr Tsoi and his work primarily focuses on the feasibility and application of Perovskite Solar Cells (PSCs) in aerospace applications.

Declan’s work is sponsored by Airbus Endeavr Wales and revolves the characterisation and stability testing of PSCs. Through his work, Declan has performed a variety of experiments including high energy particle bombardment, high and low temperature cycling and in-situ Raman spectroscopy. Declan has also developed flexible thin film perovskite devices with additional thin film encapsulation, thus allowing a much greater power-to-weight, and therefore improving the performance under space conditions. Declan has had work published in SolarRRL and the Journal of Material Chemistry C (JoMCC), with an additional paper under review.

Areas of Interest

  • Particle bombardment and interactions
  • Simulations of device mechanics under temperature strain
  • In-situ Raman spectroscopy
  • Photoluminescence (PL) & Photocurrent (PC) mapping

Dr Harrison Ka Hin Lee received his BSc in Physics and PhD under supervision of Prof. Shu Kong So from Hong Kong Baptist University in 2010 and 2015, respectively.

He then moved Swansea University as a Technology Transfer Fellow in Dr Wing Chung Tsoi’s Group. Harrison’s research interests include organic and perovskite photovoltaics for indoor and aerospace applications, semi-transparent devices, their optoelectronic properties, and their stability.

Areas of Interest

  • Organic and perovskite PV
  • Indoor PV
  • Semi-transparent PV
