Latest Patents

One of Chensha Li's latest patents is a method of storing electron hole pairs. This invention provides a device for harvesting and storing solar energy by converting solar energy to electrical energy through the photovoltaic effect. The device features a pair of electrodes, with at least one being transparent to allow solar energy to pass through. A medium is placed between the electrodes, exhibiting a combination of photovoltaic and ferroelectric properties. When solar energy passes through the transparent electrode and is absorbed by the medium, electron-hole pairs create a voltage potential between the electrodes via the photovoltaic effect. This voltage potential can be retained, and the mobile charge can be stored in the absence of solar energy through the ferroelectric effect.

Another notable patent is a passive solar tracking system designed to enhance solar cell output. This system includes a panel with at least one solar cell for solar-to-electric conversion and an actuator that moves the panel to adjust its facing direction. The actuator is directly driven by light, such as sunlight, enabling the panel to passively track and continuously face the sun. The actuator may be constructed from a composite material that includes a matrix of liquid crystal elastomer material with carbon nanotubes and an elastic skeleton defined by a 3D polyurethane fiber-network. Additionally, the actuator housing is designed to enhance stimulus delivery to the actuator, incorporating a heat collector and a light concentrator to facilitate actuation.
