Some organic materials cannot be utilized similarly to silicon semiconductors in optoelectronics. Whether in solar cells, light-emitting diodes, or in transistors, what is important is the bandgap, i.e. the difference in energy level between electrons in the valence band (bound state) and the conduction band (mobile state). Charge carriers can be raised from the valence band into the conduction band by means of light or an electrical voltage. This is the principle behind how all electronic components operate. Bandgaps of one to two electron volts are ideal.
