Electron/Hole Effective Mass vs Solar Cell efficiency

[jnguyen7]

Hi. I'm doing research relating to solar cells and came about the topic related to effective masses. The wiki article stated how effective mass (solid state materials) influences the efficiency of solar cells, but doing more research I couldn't find any solid examples of an effective mass vs. solar cell efficiency relationship. Can someone explain how effective mass influences solar cell efficiency? Does a materials' less effective mass really increase solar cell efficiency (possible due to faster carrier velocities)?

No one? This should be a basic question for anyone who has worked in semiconductors.
