Abstract : This is a highly productive research project (27 papers in three years, on journals of Science, Nature Photonics, Nature Communications, Advanced Materials, JACS, Advanced Functional Materials, Advanced Energy Materials, Nano Letters, ACS Nano, Angewandte Chemie International Edition, etc. aiming to (1) develop novel low bandgap conjugated polymers for high efficiency tandem solar cell single junction cell with 9% PCE achieved (2) develop tandem solar cell structures both polymer only and hybrid tandem cells to constantly pushing the envelope of solution processed solar cell performance 11.6% polymer tandem cell, 7% transparent tandem polymer cell, and over 10% PCE hybrid tandem solar cells were achieved. In addition, AFOSR s final support also enabled us to explore novel hybrid perovskite solar cells in depth. For example, single junction cell efficiency of 19.3% under reverse bias was achieved and the results was published on Science.
