Fabricated LDS layer on top of the asymmetric CPC designs systems - both direct and diffuse systems

Layers fabricated in 13 will be deposited on top of the solar cell in the CPC system It is very important that there should be no air gap between the layers and the solar cells The air gap can lead to reflection between the solar cell and the LDS layer producing a huge reduction of photons to be transferred to the solar cell The electricalthermal properties of the CPC system with and without the downshifting layers will be investigated Both designs will be characterised indoors under simulated solar radiation and outdoors under real conditions After characterisation improvements in the design of the integrated LDSCPC will be undertakenThis will be completed under task 17
