The present invention discloses a back contact solar cell. The back contact solar cell includes a semiconductor substrate having a front surface and a rear surface; a first conductive type semiconductor region having a first conductive type and a second conductive type semiconductor region having a second conductive type at an interval on the rear surface of the semiconductor substrate. Furthermore, the rear surface of the semiconductor substrate has a texturing structure at the interval between the first conductive type semiconductor region and the second conductive type semiconductor region.

Back contact solar cell and fabrication method thereof

The present invention discloses a back contact solar cell comprising: a first conductive type semiconductor substrate having a front surface and a rear surface of a texturing structure; an oxide layer formed on the front surface of the substrate; at least one first conductive type semiconductor region and second conductive type semiconductor region alternatively formed at predetermined intervals on the rear surface of the substrate; an oxide layer formed on the remaining rear surface of the substrate except for the first conductive type semiconductor region and the second conductive type semiconductor region; and electrodes formed on each of the first conductive type semiconductor region and the second conductive type semiconductor region.

An assembly for inserting an artificial disk is provided. The assembly includes an artificial disk, which includes a body which has a predetermined thickness to be inserted between vertebrae, and includes an incision recess incised on one side of the body in a sideways direction and a penetrating hole formed on the side on which the incision recess is formed in a vertical thickness direction, and a connecting unit which is inserted into the penetrating hole and serves as a shaft of a rotational movement of the body, and includes a connecting hole formed on a side surface of the connecting unit, and a guide protrusion, a first insertion tool which includes a connecting rod, and a handle, and a second insertion tool which includes a support rod, an insertion end, a support end, and a handle.

Artificial disk for transforaminal lumbar interbody fusion (TLIF) and insertion assembly thereof

Discussed is a fabrication method of a solar cell according to an embodiment of the invention, which includes forming an electrode material on a semiconductor substrate for the solar cell; and forming an electrode by heat treating the electrode material by laser irradiation, wherein the electrode material comprises at least one of an electrode paste, electrode ink and aerosol for the electrode.

Laser firing apparatus for high efficiency solar cell and fabrication method thereof

An automatic liquid dispenser is disclosed wherein a liquid adjustor is disposed to prevent liquid from splashing outside of a receptacle, thereby saving the automatic liquid dispenser from being polluted with splashed liquid. A receptacle and level detector emits ultrasound to the receptacle and detects the ultrasound reflected from the receptacle to generate a signal. A controller receives the signal from the receptacle and level detector to control the liquid adjusting unit, and an identifying mark at the receptacle accommodator facilitates the correct arranging of the receptacle.

Automatic liquid dispensers

Door on a laundry dryer/drum type washing machine including a door frame having a central opening, for opening/closing an opening in a front part of a cabinet for introduction/taking out of laundry, an outer window fixed to a front surface of the door frame, and an inner window fixed to a rear surface of the door frame, wherein the door frame has a front surface curved in left/right directions, and the outer window is curved the same with the door frame, thereby providing a good design of a door and improving washing and drying performance.

Door on drum type washing machine or laundry dryer

An automatic liquid dispenser and automatic liquid dispensing method are disclosed capable of transmitting ultrasonic to an upper surface of a receptacle, and receiving the ultrasonic reflected from the upper surface of the receptacle to detect a receptacle height, whereby the receptacle height may be freely detected regardless of shape, material and surface state of the receptacle, and regardless of a position where the receptacle is placed.

Automatic liquid dispenser and automatic liquid dispensing method

An automatic liquid dispenser and a refrigerator with the same is disclosed wherein a level of liquid to be ejected into a receptacle can be established, and a display module is mounted to thereby enhance a user convenience, and wherein the automatic liquid dispenser is mounted on the refrigerator to allow being independently driven and manufactured.
