摘要： Provided is a resist composition for pattern printing containing a resin (A) component that contains a combination of at least two or more types of amino group-containing resins each containing an amino group of different amine numbers respectively, the entire resin (A) component having an amine number of 1.5 to 10.0, a compound (B) component that generates an amine by means of moisture and/or light, a thickener (C) component, and a diluent (D) component. The resist composition has high resistance to an alkaline etchant, can be easily peeled off by an aqueous acid solution, and enables a protective pattern to be formed by printing.

摘要： The present invention relates to a solar cell 10 that includes: a semiconductor substrate 11; and a first conductive layer 12 and a second conductive layer 13 that are disposed on one principal surface of the semiconductor substrate 11. A first electrode 17 is disposed on the first conductive layer 12, and a second electrode 18 is disposed on the second conductive layer 13. The first electrode 17 and the second electrode 18 are electrically separated, and an island-shaped conductive layer 16 is disposed between the first electrode 17 and the second electrode 18.
