Evaluation of concentrating photovoltaic performance under different homogeniser materials

K9 glass material is 20% higher luminous transmission than the crystal resin materials. [Display omitted] •Two different homogeniser materials were characterised using spectrometer.•K9 glass homogeniser module performs higher electrical power than the crystal resin.•Homogeniser made of K9 glass experiences higher temperature than the crystal resin. In concentrating photovoltaic (CPV), increasing the incoming sunlight to the solar cell influences the performance of the solar cells. The optical efficiency of the CPV components is a key factor to improve the electrical efficiency. Two types of homogeniser materials (K9 glass and crystal resin) were investigated in the CPV application. The results show a higher power generation of the CPV module when using K9 glass homogeniser compared to the crystal resin homogeniser by 27% due to the high transmittance value of the K9 glass material. In addition, the K9 glass material shows an excellent resistance to the heat produced by the concentrated sunlight compared to the crystal resin material.
