Building Integrated Concentrated Photovoltaic (BICPV) systems are one of the options to reduce the dependency on fossil fuels and minimise energy consumption in buildings. These systems not only contribute to the generation of electricity, but also to the reduction of energy consumption by allowing the passage of ambient light and by making use of the cogenerated heat for indoor heating and/or cooling. This paper presents a novel optical concentrator called Rotationally Asymmetric Dielectric Totally Internally Reflecting Concentrator (RADTIRC) for use in BICPV systems. The RADTIRC-PV structure is capable of providing a maximum power concentration of 4.2x. Key benefits of this technology include: reduction of cost of BICPV systems, flexibility of design, and higher electrical power outputs
