Data from Hankyong National University Provide New Insights into Applied Physics

June 17, 2014

By a News Reporter-Staff News Editor at Physics Week -- A new study on Applied Physics is now available. According to news reporting from Gyeonggi Do, South Korea, by VerticalNews journalists, research stated, "We present three dimensional (3-D) amorphous silicon (a-Si:H) thin-film solar cells with silver nano-rods as back electrodes, which are fabricated by low cost nano imprint lithography (NIL). After conformal deposition of thin metal and semiconductor layers, we can achieve a dome-shaped geometry, which is shown to be effective in reducing the reflectance at the front surface due to the graded refractive index effect."

The news correspondents obtained a quote from the research from Hankyong National University, "In addition, the enhancement of the diffused reflectance over a broad wavelength in this dome-shaped geometry provides light trapping due to the increase in the effective light propagation length. Using this 3-D solar cell, we achieved 54% increase in short circuit current density and 45% increase in the conversion efficiency compared to the control cells with flat Ag surfaces."

According to the news reporters, the research concluded: "This 3-D structure can be also used for improving light harvesting in various photovoltaic devices regardless of materials and structures."
