Effect of Sb-Bi alloying on electron-hole recombination time of CsAgBiBr double perovskite.

The double perovskite material CsAgBiBr, characterized by high stability, low toxicity, and excellent optoelectronic properties, has emerged as a promising alternative to lead-based halide perovskites in photovoltaic applications. However, its photovoltaic conversion efficiency after integration into solar cell devices is less than 3%, significantly lower than that of traditional perovskite solar cells. While alloying methods have been widely applied in the design of photovoltaic materials, their specific role in modulating the lifetime of photo-generated charge carriers in double-perovskite solar cells remains inadequately explored.

Second-line treatment of PD-1 and CTLA-4 blockade combined with liposomal irinotecan plus leucovorin and fluorouracil for advanced cholangiocarcinoma: study protocol of a single-arm, prospective phase II trial.
