Symmetric Dopant‐Free Si Solar Cells Enabled by TiOx Nanolayers: An In‐Depth Study on Bipolar Carrier Selectivity

Symmetric Dopant‐Free Si Solar Cells Enabled by TiOx Nanolayers: An In‐Depth Study on Bipolar Carrier Selectivity

Abstract High‐efficiency solar cells require two contact structures, engineered for efficient extraction of photogenerated holes and electrons at the respective electrodes. Herein, crystalline Si solar cell featuring hole‐ and electron‐selective passivating contacts composed entirely of a single mat...
