The invention is a method for efficiently preparing alkali cellulose having a uniform alkali distribution therein. More specifically, pulp and an excess alkali metal hydroxide solution are introduced continuously in a screw conveyor type contactor and brought into contact with each other in the screw conveyor type reactor. By changing at least one factor selected from the group consisting of a rotation speed of the screw conveyor, a screw pitch and a length of immersion zone, a ratio of an alkali to cellulose in the alkali cellulose obtained by draining is controlled. The alkali cellulose thus obtained is etherified into the corresponding cellulose ether.

The polishing apparatus has a polishing unit capable of polishing a peripheral portion of the substrate to form a right-angled cross section. The polishing apparatus includes: a substrate holder that holds and rotates the substrate; guide rollers that support a polishing tape; and a polishing head having a pressing member that presses an edge of the polishing tape against the peripheral portion of the substrate from above. The guide rollers are arranged such that the polishing tape extends parallel to a tangential direction of the substrate and a polishing surface of the polishing tape is parallel to a surface of the substrate. The substrate holder includes: a holding stage that holds the substrate; and a supporting stage that supports a lower surface of the peripheral portion of the substrate in its entirety. The supporting stage rotates in unison with the holding stage.

Disclosed is a method of manufacturing a photoelectric conversion element including a substrate and a stacked body configured of a plurality of compound semiconductor layers of different compositions sequentially stacked on the substrate, and having at least one pn junction in the stacked body. This method includes the steps of forming the stacked body configured of the plurality of compound semiconductor layers of different compositions sequentially stacked on the substrate; forming a protective film on the stacked body; forming a groove by removing at least a portion of the stacked body by at least one method selected from the group consisting of a mechanical removing method, dry etching and laser scribing; etching a side wall of the groove using an etching solution after forming the protective film and the groove; and cutting a portion corresponding to the groove for separation into a plurality of photoelectric conversion elements. Also disclosed is a photoelectric conversion element obtained by this method.

In a solar cell, a body portion that includes at least one PN junction portion that is formed by laminating a P layer and an N layer in the front to back direction is formed. End faces of the PN junction portion form part of side faces of the body portion, and a surface electrode is formed on a surface of the body portion and a back surface electrode is formed on a back surface of the body portion. The surface electrode includes a terminal attachment portion to which a surface electrode connecting lead wire through which an electromotive force is extracted is bonded by wire-bonding or spot-welding. An anti-reflection film is formed on a surface of the surface electrode that includes the terminal attachment portion and the surface of the body portion other than a portion where the surface electrode is formed.
