PVTree: 3D photovoltaicA joint Particle Physics and Product

Design (WMG) project

R. Cain, E. Dimitrokali, G. Jones, J. Mackrill and Y. Ramachers

Summary of current research

• Current funding: Energy GRP (£10k) and Innovative Manufacturing GRP (£10k)

• Exploratory study, interdisciplinary (Physics, WMG). • Tasked to exhibit at University Anniversary 2015• Topics:

– Computational geometry optimization– Perception of a new energy harvesting structure– Added functionality, aesthetics, efficiency, all design influences

to explore and combine– Many diverse environments (urban, rural, deserts) as additional

stimulus for structure design

Summary of current research• Project on track• Computational study well advanced.• Two workshops since October.• First data analysis in progress.• Preparations for University-wide survey this term started.

PVTreeExamples:- Ternary- Helical

Future opportunities

• EPSRC Manufacturing the Future call for investigator-led proposals (Febr. or Aug.).

• EPSRC Responsive mode - open deadline• ERC consolidator or starting grant - deadline

12th March 2015 (Rebecca Cain)• For any of the above, we’ll need to bring in

additional disciplines and create a larger project team.

Backup

ApproachPart 1: Low fidelity prototype workshops (n=10)

Aim to elicit initial insights into concept and gather initial design ideas for the PVtree to create parameters for the computational model

Thematic analysis to create parameters

Part 2: High fidelity prototype workshops (n=14)Aim to refine parameters and come to a consensus

as to the form of the PVtree

Thematic analysis to refine parameters

3D printed model for evaluation

User perceptions workshops

ResultsStructure:Branch structure was that of a traditional tree with 3-5 branches rather than a number. This was a clear ‘tree’ structure of trunk and branches

Aesthetics:Natural elements were seen as a requirement, this may be through green colouring but also through growing plants up the structure. Aesthetics the same for rural/urban spaces.

PV panel form:Large PV panels. Spherical with participants commenting that this would capture a greater range of light (dispersed from other objects) and also improve the aesthetic of the panelling.

Function:The overriding function was that of seating and a form of shelter.
