How This Perovskite Breakthrough Could Change Solar Forever. What if solar panels could generate twice the power for a fraction of the cost, making them cheap enough that you`d actually want them on your roof? This is a solar cell made with both perovskites and graphene, the record-breaking result of a collaboration between three Aussie teams. This perovskite cell initially had an efficiency of 16.65%, behind the 20% efficiency range of standard silicon. The introduction of graphene, though, almost doubled that initial figure to 30.6% … all while cutting production costs by 80%. How is this possible? And more importantly, when might these actually end up on your roof?
