The transmittance of PV glass, which is the ratio of the light transmitted through it to the incident light varies with different PV coverage rates (area proportion of photovoltaic cells) and different materials of PV modules.
Lowered PV glass transmittance and the realization of natural ventilation through the DSF structure would both contribute to the reduction of solar heat gain into the room context.
This will in turn influence the PV module temperature and thus the power generation efficiency . The glass transmittance acts as an important factor affecting both the thermo-optical properties of the STPV unit itself and the overall performance of the combined system (STPV-DSF).
The outer skin with PV glass always absorbed more heat than the clear glass, resulting in a maximum temperature increase of about 4 °C. Temperature profiles of STPV-DSFs with glass transmittance of 20% and 40% presented similar trends, indicating no significant influence of the PV transmittance on the temperature distributions of STPV-DSFs.
The transmittance of conventional uncoated solar glass at a vertical incidence of light is approximately 91%. The front reflects around 4%, around 4% on the back, and 1% absorption. In addition, there are double reflections within the glass, which is in the order of 0.2%.
One approach is to consider the light-scattering effects of dust when measuring the transmittance of soiled glass samples and the differing light paths in glass samples and PV modules. The transmittance of conventional uncoated solar glass at a vertical incidence of light is approximately 91%.
