Amorphous-SI photovoltaics for commercial buildings

Objective



Objectives

Amorphous silicon (a-Si) photovoltaics (PV) is a promising option in the energy and environment conscious design of commercial buildings with large facade areas, as it may be potentially competitive with conventional premium building claddings in terms of effective cost per area. In order to exploit this potential, the objective of the project is to develop technologies and optimised system concepts for large scale deployment of a-Si PV in commercial buildings.


Technical Approach

The project aims, as a multidisciplinary effort, at developing a-Si PV-elements for use as building components, acceptable to the building community in terms of cost and technical and architectural quality, through the following actions:
- Modification of the present a-Si module production technologies towards building-specific products.
- Studying the generic architectural and electrical integration of a-Si PV in buildings.
- Developing computational tools for analysing the feasibility of a-Si options in the building environment considering also trade-off questions with other solar technologies.
- Constructing test facades and analysing the regulations related to the use of a-Si PV in buildings.


Expected Achievements and Exploitation

The following key project results are expected:

- Samples of large area multi-functional a-Si PV-elements. - A quantitative methodology, including design tools, for optimising the a-Si PV use in commercial buildings.
- Optimum electrical, building and architectural integration methods specifically for a-Si.
- Regulatory acceptability of a-Si components in accordance with European building codes.
- Generic guidelines for the deployment of a-Si PV in building projects and for the basis of further R&D&D.
