How is direct to diffuse solar transmittance calculated?

Using the individual transmittance calculated for the outer glass pane, PMMA capillary cells, and inner glass pane with the presented mathematical models, the direct to diffuse solar transmittance through the entire TI-system was calculated by evaluating and multiplying each individual transmittance to give a combined transmittance value.

What are transparent photovoltaics (TPVs)?

Transparent photovoltaics (TPVs), which combine visible transparency and solar energy conversion, are being developed for applications in which conventional opaque solar cells are unlikely to be feasible, such as windows of buildings or vehicles.

What is the solar transmittance of PMMA capillary cells at 0° incidence angle?

The calculated transmittance for the PMMA capillary cells at 0° incidence angle was 0.8264 with overall solar transmittance of up to 0.66 calculated for the whole TI-system, a value which is consistent with that found in previous research.

What happens when solar beam radiation passes through the TI-system?

When solar beam radiation passed through the TI-system, the solar transmittance, absorptance and reflectance that occurred in the system were calculated. Optical interactions at each layer in the TI-system were numerically modelled for five incidence angles.

How is a solar ray transmitted through multiple PMMA capillary cells?

When a solar ray was transmitted through multiple PMMA capillary cells at an incidence angle of θi, a direct to diffuse transmittance was predicted. The solar ray was either reflected or transmitted towards the inner glass pane, resulting in scattering of the light over a large area.

What is a solution based transmittance spectrometer?

Historically, solution-based transmittance measurements have utilized solvent-only cuvettes in double-beam spectrometer as a reference to (nearly perfectly) subtract all reflectance and arrive at absorbance spectra (Figure 1 D).
