| Abstract Scope |
We have designed a synergistic Photothermal (PT)-Thermoelectric (TE)-Photovoltaic (PV) module for energy generation by utilizing the full spectrum of solar light. The core component is a transparent photothermal spectral modulator (TPSM) that captures solar light and segregates photon energies proportionally for PT, TE, and PV. Spectral modulation is achieved by structural design of nano hybrids of porphyrin and iron oxide compounds with unique optical absorptions. The IR portion is photothermally converted to heat up the TE hot end, creating the temperature span for generation of electricity, while the UV/visible part is directed towards PV to improve power conversion efficiency (PCE). By removing IR, the PV surface temperature is lowered, resulting in a PCE increase from 16.3% to 19.4% after 120 minutes of solar irradiation. When combined with commercial thermoelectric generators (TEG), the system achieves a total efficiency of 21.8%, surpassing the average efficiency of the commercial silicon PV panel. |
