The Potential for Hot Carrier Collection from an Amorphous Absorber

What is it about?

The quest for clean, inexpensive sources of energy has produced intense interest in low-cost methods for dramatically increasing the efficiencies of solar cells. Standard solar cells have limitations3 on their theoretical efficiencies in part due to the fact that carriers excited by light with energies above the semiconductor’s band gap quickly lose some of their energy to heat (thermalize), which can be overcome by collecting the carriers before they thermalize. However, since carriers therma

Why is it important?

The ability to absorb light and create carriers of electricity in a wide variety of highly absorbing amorphous matrices and then collect these carriers in a highly efficient collection of nano-sized crystals will dramatically increase the efficiencies of thin film solar cells.
