Latest Patents

One of Qi Xu's latest patents is a "Transmissive concentrated photovoltaic module with cooling system." This innovative design proposes a spectrum-splitting, transmissive concentrating photovoltaic (tCPV) module intended for a hybrid photovoltaic-solar thermal (PV/T) system. The system is designed to fully utilize the incoming sunlight spectrum. By employing III-V triple junction solar cells with specific bandgaps, the module effectively converts ultraviolet and visible light into electricity while allowing infrared light to pass through to a solar thermal receiver. This design can achieve an overall power conversion efficiency exceeding 43.5% under standard solar conditions. Additionally, the module incorporates both passive and active cooling methods to maintain optimal cell temperatures.

Another significant patent by Qi Xu is "Infrared transmissive concentrated photovoltaics for coupling solar electric energy conversion to solar thermal energy utilization." This invention addresses the limitations of traditional photovoltaic cells by providing a high-efficiency solar power system that can supply electricity competitively. The device combines aspects of concentrated solar power and concentrated photovoltaics, allowing for efficient sunlight conversion and thermal energy transmission. The use of a multijunction PV cell mounted on a transparent base enables the absorption of high-energy light while transmitting lower-energy light to thermal storage devices.
