The various embodiments herein provide an energy efficient DC off-grid home system and a method for operating the same. The system generates, stores and delivers the solar energy to the connected equipments in a controlled and efficient manner. The system has several solar panels, a battery bank, a home control unit, several appliances and equipments which run on electric power and a remote terminal unit. The solar panels are used to capture maximum solar energy from the sun. The battery bank has several batteries arranged in series and parallel combinations to store maximum electrical energy. The home control unit is a central control station which assists in storing energy in the battery bank, delivering optimum energy to the electrical appliances and monitoring the healthy operating status of the entire system.

Intelligent and efficient off-grid solar home energy system and method thereof

A very thin photovoltaic cell is formed by implanting gas ions below the surface of a donor body such as a semiconductor wafer. Ion implantation defines a cleave plane, and a subsequent step exfoliates a thin lamina from the wafer at the cleave plane. A photovoltaic cell, or all or a portion of the base or emitter of a photovoltaic cell, is formed within the lamina. In preferred embodiments, the wafer is affixed to a receiver before the cleaving step. Electrical contact can be formed to both surfaces of the lamina, or to one surface only.

Method to form a photovoltaic cell comprising a thin lamina

Methods for bonding a donor wafer to a receiver element and transferring a lamina from the donor wafer to the receiver element are disclosed herein. The donor wafer may be, for example, a monocrystalline silicon wafer with a thickness of from about 300 microns to about 1000 microns, and the lamina may be may be less than 100 microns thick. The receiver element may be composed of, for example, metal or glass, and the receiver element may have dissimilar thermal expansion properties from the lamina. Although the lamina and the receiver element may have dissimilar thermal expansion properties, the methods disclosed herein maintain the integrity of the bond between the lamina and the receiver element.
