New Materials for Hybrid Photovoltaics
Wed, 13/04/2016 - 16:00 to 17:00
Location:
Speaker:
Prof. Neil Robertson
Affiliation:
University of Edinburgh
Synopsis:
The talk will address new materials for perovskite solar cells (PSC) and solid-state dye-sensitised solar cells (ssDSSC). PSCs have brought a paradigm shift in efficiencies of solution based photovoltaics. Triarylamine (TAA)-based materials, especially Spiro-OMeTAD, have been the most promising hole-transport materials (HTM), however Spiro-OMeTAD is one of the most costly layers of the PSCs. Considering this, we have prepared novel triarylamines with varying oxidation potentials and varying alkyl chain length, which exhibit excellent performance when tested in PSCs. Analogues with different oxidation potentials have been studied in both perovskite and solid-state dye-sensitised solar cells to understand the role of driving force in hole extraction. For ssDSSCs, we have also explored a range of new dyes with design that differs from the common donor-pi-acceptor motif that is ubiquitous in the literature.
