Abstract

One example embodiment includes a PV module comprising a conductive backsheet, a non-conductive layer disposed on the conductive backsheet, a plurality of PV cells arranged in rows and collectively generating a first power output characterized by a first voltage, and a power conversion device. Each of the rows can include two or more PV cells. The PV cells within each row can be connected to eachother in parallel. The rows can be connected in series. A top row can be connected to the conductive backsheet. The power conversion device can be redundantly connected to a bottom row and to the conductive backsheet to form a complete circuit. The power conversion device can convert the first power output to a second power output characterized by a second voltage that is larger than the first voltage. The power conversion device can also maintain peak power of the PV cells.

Description

technical field [0001] The present invention generally relates to photovoltaic ("PV"; photovoltaic) systems. More specifically, embodiments of the present invention relate to PV modules adapted to operate under non-uniform lighting conditions. Background technique [0002] There are two main types of solar collectors commonly used in PV modules, including silicon and thin film, solar collectors are usually constructed from PV cells. Silicon is the predominant technology used today and is generally realized as monocrystalline or polycrystalline silicon cells encapsulated behind a transparent glass front. Thin-film technology is not as widely used as silicon technology because of its low efficiency, but it is also popular because of its lower cost. [0003] Currently, the solar industry is looking for ways to reduce the cost per unit of energy produced by PV modules. One way to reduce the cost per unit of energy is to increase the time a PV module is exposed to solar energy...
