Photoluminescence quenching and hot carrier transfer in nanocrystalline silicon
Author(s):Miller, Levi; Fields, Jeremy; Collins, Reuben T.; Taylor, P. Craig
The maximum efficiency of silicon photovoltaic cell is not 31% but 74%. Collecting hot carriers before they thermalize is a means to achieve this. In this regard, amorphous semiconductors are potentially useful materials. ...
