New benchmark in p-type dye-sensitised solar cell performance

摘要

The development of renewable energy technologies is vital for meeting the increasing energy demands of the modern world and for lowering greenhouse gas emissions and environmental pollution from fossil fuel combustion. Towards this end, many approaches to harvesting solar energy have been explored. The dye-sensitised solar cell (DSC) is one promising device that can potentially be constructed at low cost and with environmentally friendly components. Efforts are being made to develop n-type and p-type DSCs that can be combined into high-efficiency tandem DSC devices. But the poor efficiency of p-DSCs has hampered the performance of such tandem devices.
