A BIPV / T system based on nanofluidic spectral beam splitting PV / T components and independently controllable thermoelectric cooling.

Abstract

This invention discloses a BIPV / T system based on nanofluidic spectral beam splitting PV / T modules and independent thermoelectric and cooling control, belonging to the field of integrated solar photovoltaic and photothermal applications in buildings. This system utilizes the spectral frequency division characteristics of nanofluids to precisely split incident sunlight at the bandgap wavelength of photovoltaic cells, allowing different wavelengths of light to be used for power generation and heat generation respectively. This achieves effective decoupling of the photovoltaic and photothermal components, thereby balancing the photovoltaic and photothermal conversion performance, achieving efficient utilization of the entire spectrum, and thus improving the overall utilization efficiency of solar energy. This invention can also regulate the building's demand for heating and cooling loads. Through optimization of the supply and demand sides, it achieves dynamic matching between supply and demand. The BIPV / T system based on nanofluidic spectral beam splitting and independent thermoelectric and cooling control changes the traditional building energy supply method, providing a new path and solution for green, low-carbon, and sustainable building development.
