Customer ServiceHowever, when it was fabricated into a complete device, the AVT of the cell increased to 7.04 %. This means that the transmittance of the CdTe film when converted into a device, not only did not decrease but increased, which is highly beneficial for the BIPV application of the solar cell.
Firstly, the transmittance of the full solar spectrum by commonly used glass materials in buildings was investigated, and the transmittance characteristics of five glass materials to the solar spectrum by different wavelengths were discussed, and then the transmittance model are established.
The results clearly show that the emerging thin-film TPVs are a promising solution to the dilemma of high energy demand and limited space in urban areas. However, the emerging thin-film TPVs are still at their infancy stage, with the PCE lagging behind their opaque counterparts and transparency below the application requirements.
Finally, as shown in Fig. 11 (a), we successfully fabricated a semitransparent CdTe solar cell with an average transmittance of 14.21 % in the wavelength range of 500 nm to 800 nm, meeting the usage requirements for BIPV.
The effect of different inclination angles of the glass on the solar spectrum transmittance is investigated using the control variable method. The control glass material was a single-pane clear glass and was adjusted for the inclination angle. The modified values were calculated using Eq.
Secondly, the solar radiation transmittance at different wavelengths is tested by considering both the glass material and the inclination angle, and a solar radiation transmittance modified model (SRTM model) that can be modified to the SRTB model is established.
