Tandem Solar Cells Edge Towards 30% Efficiency
The production of more efficient solar cells is heating up with recent announcements that a commercially available solar cell is able to produce energy with record 29.52% efficiency. While new materials called Perovskites seem to be the future for solar cell construction, new tandem materials where Perovskites and silicon work in tandem are beginning to push boundaries.
Local researchers are also working on Perovskites, researchers from the University of Queensland have used titanium carbide nanosheets doped with cesium (Cs) to fabricate perovskite solar cells which they claim deliver a PV efficiency of up to 21.57% with “excellent thermal stability”.
