<P>PROBLEM TO BE SOLVED: To provide a photoelectric transducer not only attaining a lightening and the reduction of a cost by decreasing the use of a semiconductor but also being capable of sufficiently collecting a light to crystal semiconductor grains. <P>SOLUTION: The photoelectric transducer has a conductive substrate 1, a large number of spherical first conductivity type crystal semiconductor grains 2 forming second conductive type semiconductor sections 3 on surface layers and being mutually joined at intervals on the conductive substrate 1 and insulating layers 4 formed among the crystal semiconductor grains 2 on the conductive substrate 1. The photoelectric transducer further has light reflecting members 7 being formed on the insulating layers 4 and having recessed surface-shaped light reflecting surfaces collecting a light to the crystal semiconductor grains 2 and opening sections exposing the upper sections of the crystal semiconductor grains 2 at the lower end sections of the light reflecting surfaces and light-transmitting conductive layers 5 continuously coated on the crystal semiconductor grains 2 and the light reflecting members 7. <P>COPYRIGHT: (C)2008,JPO&INPIT |
