Abstract
Official abstract text for this publication.
Device structures, apparatuses, and methods are disclosed for photovoltaic cells that may be a single-junction or multijunction solar cells, with at least a first layer comprising a group-IV semiconductor in which part of the cell comprises a second layer comprising a III-V semiconductor or group-IV semiconductor having a different composition than the group-IV semiconductor of the first layer, such that a heterostructure is formed between the first and second layers.
First claim
Opening claim text (preview).
We claim: 1. A tunnel junction for a photovoltaic cell, said tunnel junction comprising: an epitaxially grown tunnel junction first layer comprising a group-IV material having p-type or n-type doping and having a first material composition; and an epitaxially grown tunnel junction second layer comprising a group-IV material having p-type or n-type doping and having a second material composition, said second material composition being different from the first layer group-IV mater…
