“…Figure 1 shows a cross-section of a GOCRSH concentrator. The detailed information on how to produce GOCRSH was discussed recently by Freier Raine et al [12] and will not be covered in this paper. To simplify the analysis, a specific GOCRSH concentrator design, labelled as GOCRSH_A, will be used, and its characteristics are presented in Table 1.…”

“…This paper aims at assessing the embodied energy and cost impacts of a static concentrating photovoltaic (CPV) module relative to a flat photovoltaic (PV) module. The CPV module employs a specific concentrator design from the Genetically Optimised Circular Rotational Square Hyperboloid (GOCRSH) concentrators proposed by Freier Raine et al [12]. A "cradle-to-grave" analysis of the GOCRSH_A module is out of scope for this paper, due to the limited time allocated to this project.…”

This paper focuses on the embodied energy and cost assessments of a static concentrating photovoltaic (CPV) module in comparison to the flat photovoltaic (PV) module. The CPV module employs a specific concentrator design from the Genetically Optimised Circular Rotational Square Hyperboloid (GOCRSH) concentrators, labelled as GOCRSH_A. Firstly, it discussed previous research on life cycle analyses for PV and CPV modules. Next, it compared the energy embodied in the materials of the GOCRSH_A module to the energy embodied in the materials of a flat PV module of the same electrical output. Lastly, a comparison in terms of cost is presented between the analysed GOCRSH_A module and the flat PV module. It was found that the GOCRSH_A module showed a reduction in embodied energy of 17% which indicates a reduction in embodied carbon. In terms of cost, the costs for the GOCRSH_A module were calculated to be 1.71 times higher than the flat PV module of the same electrical output. It is concluded that a trade-off is required between the embodied energy and cost impacts in order to bring this CPV technology into the market.

“…Based on the ray tracing analysis of the CRSH they concluded that a maximum optical concentration gain of 3.94x can be achieved. The CRSH was recently optimized using genetic algorithms, and the new design is known as genetically optimized circular rotational square hyperboloid (GOCRSH) concentrator (Freier Raine et al, 2020).…”

Photovoltaics (PV) is one of the most promising renewable energy technologies thanks to the ubiquitous access to solar radiation around the globe, as well as the development of multijunction PV that has increased power conversion efficiency (PCE) above the single junction limits in the past half century. [1,2] To fully realize the power production potential of PV, solar cells with higher PCEs and deployment in greater areas are required. Although the costs of silicon solar cells have been dramatically reduced in recent years, their application potential in new areas such as buildingintegrated PV, mobile power, and transportation is limited since standard silicon panels are simply too bulky, heavy, rigid, and inefficient for these applications. Multijunction solar cell technologies based on III-V semiconductors with the highest PCEs still suffer from large unit costs due to expensive materials and complicated fabrication processes, and are therefore used almost exclusively in space applications or small installations that are impractical for large-scale terrestrial power production. [3][4][5] Concentrator photovoltaics (CPV) systems have long been considered a potential solution to such difficulties. [6] Implementing optical concentrators allows for cost-efficient harvesting of solar radiation from a much larger area than that of the PV device, since it replaces expensive semiconductor photoelectronic materials with less expensive materials for the concentrator optics. [7] Moreover, it is well known that solar cells made from high-mobility crystalline materials can benefit from higher incident radiation intensities to produce higher PCEs at increased open-circuit voltages (V oc ), making concentrators almost a necessary component for large-scale commercialization and terrestrial deployment of III-V high-PCE multijunction solar cells. [8][9][10] Building-integrated photovoltaics (BIPV) is a popular nextgeneration implementation of PV systems with unique requirements. [11] Direct integration of PV into the building envelope enables the utilization of a large portion of existing building surface area to generate power, and reduces costs related to electricity transportation and distribution. [12] The utilization of BIPV systems as building envelope materials has the potential to not only enable cost savings, but also become a source of income for a building.
