Abstract:
A photoelectric conversion element comprising a substrate, a lower conductive layer, a first doped layer, an i-layer, a second doped layer, and an upper conductive layer, whereina surface of said lower conductive layer has an uneven shape,said i-layer contains prismatic crystalline grains,longitudinal directions of the prismatic crystalline grains are inclined with respect to a direction of a normal line to said substrate,a percentage of an overall volume of the prismatic crystalline grains, each having a below-defined angle of 20.degree. or less, is 70% or more with respect to an overall volume of the i-layer, andsaid angle is an angle made between a straight line A passing said prismatic crystalline grain and being parallel to a longitudinal direction thereof and a straight line B passing said prismatic crystalline grain out of straight lines taking shortest courses between interface 1 between the first doped layer and said i-layer and interface 2 between the second doped layer and the i-layer.
