High efficiency photovoltaic roof tiles with static concentrators
- Univ. of New South Wales, Sydney, New South Wales (Australia). Centre for Photovoltaic Devices and Systems
The use of static concentrators provides a level of concentration sufficient for significant cost reductions, without any of the problems of high concentration systems. There is no need for expensive tracking, most of the diffuse light is collected and passive cooling can be used for the cells. Following the construction of prototypes that confirm computer ray tracing predictions a structure has been designed for the manufacture of a 1 kW roof top array in association with the state power authority. Two manufacturing techniques for the array and potential commercial production are described. The pilot line at the University of New South Wales has commenced production of bifacial buried contact solar cells for the project. These cells provide the necessary high efficiency and low cost. Measurements have been made on the amount of dust likely to be present on a typical module, the effect on total internal reflection and thus the concentrator performance.
