Abstract

Solution-processed organic solar cells (OSCs) are promising low-cost, flexible,
portable renewable sources for future energy supply. The state-of-the-art OSCs
are typically fabricated from a bulk-heterojunction (BHJ) active layer
containing well-mixed donor and acceptor molecules in the nanometer regime.
However, BHJ solar cells suffer from stability problems caused by the severe
morphological changes upon thermal or illumination stress. In comparison,
single-component organic solar cells (SCOSCs) based on a double-cable
conjugated polymer with a covalently stabilized microstructure is suggested to
be a key strategy for superior long-term stability. Here, the thermal- and
photostability of SCOSCs based on a model double-cable polymer is
systematically investigated. It is encouraging to find that under 90 °C & 1
sun illumination, the performance of SCOSCs remains substantially stable.
Transport measurements show that charge generation and recombination (lifetime
and recombination order) hardly change during the aging process. Particularly,
the SCOSCs exhibit ultrahigh long-term thermal stability with 100% PCE
remaining after heating at temperature up to 160 °C for over 400 h, indicating
an excellent candidate for extremely rugged applications
