Professor Hari Reehal joined LSBU from BP Research (Sunbury) where he led research groups working in the areas of photovoltaics, novel thin film materials, coatings and surface science. Prior to this he was a Lecturer in Applied Physics at the University of Bradford.

At LSBU he has held various positions, including Director of Research in the former Faculty of Engineering, Science and the Built Environment and the Department of Engineering and Design. He was also Head of the Centre for Advanced Materials.

Hari is currently an Emeritus Professor in the School of Engineering and a member of the Centre for Advanced Materials.

Hari teaches the following modules:

  • Engineering Applications 2 (Module Leader)
  • Design Engineering 2
  • Digital Techniques
  • Renewable Energy Technologies
  • Final year projects (BEng Electrical and Electronic Engineering)

Current research is focused on (i) novel electronic and functional materials for renewable energy generation using PV devices or solar cells and (ii) the application of PV.

Solar cell research targets the growth, processing and characterisation of:

  1. Thin film crystalline silicon cells on cheap substrates as a lower cost replacement for conventional silicon wafer technology which currently dominates the PV market.
  2. Plasmonic solar cells. The aim here is to incorporate nanoscale metal particles into thin crystalline silicon solar cells to increase light absorption and improve cell efficiency.
  3. Nano- and micro-wire silicon solar cells. In these the device junctions are radial. This and the excellent light trapping properties of these structures are promising for increased cell efficiencies and reduced material use.
  4. Thin film transparent conducting oxides and new low cost materials for PV.

Research in PV applications includes modelling and experimentally studying the performance of different PV modules and systems.

The research is supported by a comprehensive range of experimental facilities for thin film growth, device processing and characterisation including a class 10,000 clean room.

Funding has been attracted from the EPSRC (including the PV 21 SUPERGEN consortium), the Leverhulme Trust and industry.
