Understanding the Impact of Bromide on the Photovoltaic Performance of CH3NH3PbI3 Solar Cells
An optimum amount of lead bromide (1%) can enhance the power conversion efficiency of CH3NH3PbI3-xBrx (where x approximate to 0) devices from 14.7% to 16.9% without altering the bandgap of the perovskite material.
