Dataset of Optical efficiency measurements for a building-integrated concentrator PV module

This dataset contains the data of the optical efficiency of the building-integrated concentrator PV module presented at 42nd European Photovoltaic Solar Energy Conference in Bilbao (EUPVSEC 2025) through the oral presentation "Fabrication of a Novel Semi-Translucent BIPV Module Providing High Power Density and Active Daylight Management" by Almudena Garcia-Sanchez. This dataset includes measurements of optical efficiency obtained using a collimated solar simulator (Helios 3198):• Optical efficiency of each lens at a concentration of 2.8 suns (with an 8 mm cell width). See Figure 8 in the conference proceedings manuscript.• X-axis scans using a 1 mm cell width for different angles of incidence (AOIT). See page 020258-016 in the conference proceedings presentation.• Optical efficiency evaluated at different sun concentrations at AOIT=17º. See page 020258-016 in the conference proceedings presentation. The authors gratefully acknowledge the support from project grants: MICROBEAM ref.
