PROBLEM TO BE SOLVED: To provide an integrated optical conversion device which uses a high-performance optical conversion element cell, and a method of manufacturing the integrated optical conversion device that decreases the number of processes and reduces the cost. SOLUTION: The optical conversion element cell 20 includes a plurality of unit cell elements 15a, 15b, 15c and 15d which are insulated and separated on a common substrate 8 with separation grooves 14a, 14b and 14c having a predetermined width, and electrically connected in series, each of the unit cell elements comprising a back electrode layer formed on the substrate 8 and provided with a back electrode lead-out portion, a crystalline semiconductor layer formed on a surface of a part, other than the back electrode lead-out portion, of the back electrode layer, and generating a pn junction by light irradiation, and a transparent surface electrode layer formed on the crystalline semiconductor layer and provided with a grid electrode. A plurality of optical conversion element cells 20 are electrically connected in series to obtain the integrated optical conversion device. COPYRIGHT: (C)2010,JPO&INPIT
