Graphene – an allotrope of carbon which is strong, transparent and a good conductor of heat and electricity. An obvious use for this material is in the manufacture of light emitting diode bulbs. Currently LED’s have a light output limited by the heat they generate which adversely affects the semiconductor. Hitherto this material is held between metal electrode – the downside being that metals are opaque and light is absorbed and turned into heat. Graphene electrodes do not suffer this disadvantage yet can be made smaller since they are stronger and can still conduct the heat away. Hence a probable saving of 20% in power wastage over current LED bulbs.
I predict a similar improvement by the adoption of graphene in the electrodes of solar panels ……. for the same reasons.
