How does morphology of donor acceptor blend of organic solar cell affect the long term stability?
Best insight from top research papers
The morphology of the donor-acceptor blend in organic solar cells (OSCs) significantly impacts long-term stability. Various strategies have been explored to enhance stability, such as tailoring blend morphology, introducing symmetry-asymmetry dual-acceptor systems, and utilizing size-controlled V-shaped blades for film fabrication. These approaches aim to optimize the morphology of the active layer to prevent phase separation, enhance molecular packing, and reduce trap-assisted recombination. By achieving well-mixed morphologies, optimized crystallinity, and suppressed phase separation, OSCs exhibit improved stability under thermal stress, maintaining high efficiencies even after extended periods. These advancements highlight the critical role of morphology control in enhancing the long-term stability of OSCs .

How can the stability of perovskite solar cells be improved?5 answersThe stability of perovskite solar cells (PSCs) can be improved through various strategies. One approach is to eliminate excess lead(II) iodide (PbI2) formation, as it accelerates perovskite degradation. This can be achieved by controlling the vapor pressure and stoichiometry of precursor solutions, which eliminates PbI2 inclusions and improves the phase stability of the perovskite film. Another strategy involves addressing stability concerns in each functional layer of PSCs. This includes using metal oxide electron transport materials with reduced surface defects, hole-conductor-free device configurations, and stable back electrodes. Surface modifications with self-assembled monolayers (SAMs) can also enhance stability, with the combination of ethanolamine and [2-(9H-carbazol-9-yl)ethyl]phosphonic acid (2PACz) showing improved interfacial defect passivation and significantly enhanced device stability. Additionally, the microstructure, charge transport, and stability of tin-based perovskite solar cells (TPSCs) can be improved by introducing piperazine iodide (PI) into the precursor solution, which regulates crystallization, inhibits Sn2+ oxidation, and reduces trap states. These strategies contribute to the overall improvement of stability in PSCs.
