<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive and reliable photoelectric converter. <P>SOLUTION: The photoelectric converter includes: a large number of granular crystal semiconductors 2 exhibiting one conductivity type which are arranged on a substrate 1 serving as one electrode; an insulator 3 which is interposed between the granular crystal semiconductors 2; a semiconductor layer 4 exhibiting the opposite conductivity type which is formed on the granular crystal semiconductors 2; and a conductive layer 5 serving as the other electrode, which is formed on the semiconductor layer 4 exhibiting the opposite conductivity type. Since the insulator 3 consists of polyimide curing at 250°C or lower and is interposed between the semiconductor layer 4 and the conductive layer 5 in lower portions of the granular crystal semiconductors, a clean and large PN junction surface can be assured and the insulator 3 can be obtained without causing any thermal damage to the PN junction. Accordingly, compared with a conventional photoelectric converter, the photoelectric converter having a high conversion efficiency can be manufactured easily at a low cost. Thus, the reliable photoelectric converter can be provided. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
