Hot carrier solar cells: Challenges and recent progress.
In: "35th IEEE Photovoltaic Specialists Conference, PVSC 2010", 20/06/2010 - 25/06/2010, Hawaii, EEUU. ISBN 978-1-4244-5890-5.
The limiting efficiency on the conversion efficiency of terrestrial global sunlight is not circa 31%, as commonly assumed, but 74%. To reach the lowest possible costs and hence to attain its intrinsic potential as a major source of future sustainable energy supplies, it would appear photovoltaics has to evolve to devices targeting the latter efficiency rather than the former. The hot carrier solar cell, although presenting substantial device challenges, is arguably the highest efficiency photovoltaic device concept yet suggested and hence worthy of efforts to investigate its practicality. Challenges in the implementation of hot carrier cells are identified and progress in overcoming these are discussed.
