Spectral Transmittance of Di-methyl Silicon Oil as a Heat Transfer Material for Concentrator Solar Cells

The accelerated life test was carded out to investigate the change of spectral transmittance of di-methyl silicon oil and the effects on the electrical performance of silicon solar cell. The di-methyl silicon oil samples be- fore and after accelerated life test were analyzed by FT-IR, GC-MS and LC-MS. The ring compounds and linear compounds with larger molecular weight were detected. The spectral transmittance of di-methyl silicon oil de- creased because the chromophore and auxochrome of the products made a sunlight receive decrease on the surface of the solar celt, and resulted in the reduction of cell performance. According to the decrease of spectral transmit- tance of di-methyl silicon oil, two recovery methods were proposed. The results showed that extraction was supe- rior to vacuum distillation in recovering the aged di-methyl silicon oil.
