Systems and methods are provided for wirelessly transferring power to a multi-junction photovoltaic cell of a space apparatus via a light emission system. The light emission system uses multiple lasers emitting different wavelengths and/or photon energies to produce electron-hole pairs in each layer of the multi-junction photovoltaic cell to prompt power generation by the multi-junction photovoltaic cell. The light emission system may be located on Earth or on another space apparatus. The multi-junction photovoltaic cell can convert sunlight and the light emitted by the light emission system into electrical energy.
