High Performance All-Polymer Solar Cells with 11.66% Efficiency and Long-Term Stability by Employing Novel π-Conjugated Donor Polymer with Nonhalogenated Green Solvent |
| 초록 |
All-polymer solar cells (All-PSCs) exhibit excellent long-term device stability and tunable good active layer morphology processed from different nonhalogenated solvents by different conditions. In this work, we found that the photovoltaic performance of all-PSCs can be further developed to a benchmark PCE of 11.66% using novel p-type π-conjugated donor polymer (Nap-SiBTz) and n-type acceptor polymer (N2200). This strategy of novel π-conjugated donor polymer enhancing the absorption coefficient, increasing the charge carrier mobility, and elements distribution are beneficial in achieving high photovoltaic performance with thick active layer. Notably, to overcome the severe charge recombination and energy losses, a 1-phenylnapthalene (1-PN) additive is used to well-ordered micro-structure, molecular packing that inherently suppresses the optoelectronic defects. Importantly, this is the highest reported PCE for a nonhalogenated solvent-processed all-PSCs so far. |
