PHOTOVOLTAIC CELL, IN PARTICULAR SOLAR CELL, AND METHOD OF PRODUCING A PHOTOVOLTAIC CELL

摘要

The invention relates to a photovoltaic cell, in particular a solar cell, comprising a absorber layer which is arranged in front of an anti-reflection layer, wherein the anti-reflection layer comprises a nanostructured layer with periodically arranged antenna elements of an electrically conductive material being arranged at a distance of 1 to 50 nanometers from the absorber layer.

主权项

1. A photovoltaic cell, comprising:
an absorber layer; an anti-reflection layer is arranged in front of said absorber layer, said anti-reflection layer comprising:
a nanostructured layer having periodically arranged antenna elements made of an electrically conductive material, said antenna elements being arranged in a regular pattern at a distance of 1 to 50 nanometers from said absorber layer and being is at least partially received within said anti-reflection layer;wherein said nanostructured layer together with a back contact of said photovoltaic cell forms an optical resonator;wherein said antenna elements are arranged at a distance of 2 to 20 nanometers from said absorber layer;wherein said antenna elements are arranged periodically with respect to each other at distances of 200 to 800 nanometers; andwherein said antenna elements have a height of 10 to 200 nanometers.
