    Abstract: A method for manufacturing a solar cell is discussed. The method may include injecting first impurity ions at a first surface of a substrate by using a first ion implantation method to form a first impurity region, the substrate having a first conductivity type and the first impurity ions having a second conductivity type, and the first impurity region having the second conductivity type; heating the substrate with the first impurity region to activate the first impurity region to form an emitter region from the first impurity region; etching the emitter region from a surface of the emitter region to a predetermined depth to form an emitter part from the emitter region; and forming a first electrode on the emitter part to connect to the emitter part and a second electrode on a second surface of the substrate to connect to the second surface of the substrate.

    Abstract: A nozzle for a cleaner may comprise a nozzle housing and a rotation cleaning unit rotatably disposed under the nozzle housing. The rotation cleaning unit may comprise a mop configured to clean a floor and a rotation plate coupled to the mop. The nozzle may comprise a driving device disposed in the nozzle housing and comprising a motor configured to drive the rotation cleaning unit, and a water tank mounted on the nozzle housing and configured to store water. The mop may comprise a floor cleaning portion, an attaching portion disposed above the floor cleaning portion to be coupled to the rotation plate, and an upper absorbing portion disposed above the floor cleaning portion and at least partially overlapping the attaching portion. The upper absorbing portion may be sewn to the attaching portion and may be configured to absorb water from the water tank.

    Abstract: A nozzle for a cleaner includes a nozzle housing that has a suction flow path that allows air containing dust to flow therethrough. The nozzle also includes a driving device including a driving motor. Further the nozzle includes a rotation cleaning unit including a rotation plate which is connected to the driving device at a lower side of the nozzle housing. The nozzle also includes a mop attached to a lower side of the rotation plate. In addition, the nozzle includes a water tank mounted on an upper side of the nozzle housing and configured to store water. The water tank is separable from the nozzle housing. An upper side wall of the water tank forms an upper surface of the nozzle when the water tank is mounted on the nozzle housing, and a portion of a bottom wall of the water tank is configured to surround the driving device.

    Abstract: A fluid compressor includes a case, a fixed scroll, an orbiting scroll, a motor, and at least one anti-rotation unit. The case is configured to form an external appearance thereof. The fixed scroll is fixed in the case. The orbiting scroll is engaged with the fixed scroll at one side of the fixed scroll, and performs partitioning of a compression chamber. The motor provides the orbiting scroll with drive power. The anti-rotation unit is coupled to a side surface of the orbiting scroll so as to prevent rotation of the orbiting scroll.
