Abstract:
1. A solar photovoltaic energy conversion apparatus, comprising: a substrate, said substrate being selected from the group consisting of glass, quartz and mono-crystalline aluminum oxide; a transparent conductive oxide thin film layer being formed on said substrate; a p-type transparent conductive oxide layer being formed on said transparent conductive oxide thin film layer; a plurality of protrusions with fixed spacing being formed on said p-type transparent conductive oxide layer, wherein every protrusion containing a separated p-type silicon semiconductor layer formed under a separated n-type silicon semiconductor layer; a n-type transparent conductive oxide layer being formed over and covering said protrusions and said p-type transparent conductive oxide layer, wherein said p-type transparent conductive oxide layer directly contacting said n-type transparent conductive oxide layer so that a plurality of transparent p-n junctions formed between said p-type transparent conductive oxide layer and said n-type transparent conductive oxide layer; and an anti-reflective layer being formed on said n-type transparent conductive oxide layer to form the solar photovoltaic energy conversion apparatus.
