Advanced Photovoltaics

Principal Investigator Jeehwan Kim


Over the past few decades, the levelized cost of energy for solar cells has decreased rapidly leading to the global average solar module cost of ~1 $/W. However, despite these advances, grid parity remains a goal for the future. There is still a substantial room for improving the solar cell efficiency, as the performance gap between the best research cell and the Shockley–Queisser limit is still 20-50%. Our group investigate nanotechnology for reducing both this performance gap and the module cost by increasing the efficiency of low-cost solar cells. Our current interests are as following: i) Geometry modification for efficiency enhancement via constructing high aspect-ratio three-dimensional solar cells, ii) Work-function engineering of carbon-based transparent electrode via plasmonic gold nanodots, and iii) Monolithic integration of organic-inorganic hybrids
