This study focuses on the photovoltaic performance of MoSe2 nanosheet-based bulk heterojunction polymer solar cells, with particular attention paid to power conversion efficiency (PCE) and other important parameters. The PCE values of the pure solar cell are 5.88%, while those of NS1, NS2, and NS3 are 6.61, 8.39, and 7.37%, respectively. The optimized MoSe2 NS2 hybrid at 5 wt % in the active layer exhibits the highest PCE of 8.39%, the highest short-circuit current density of 15.865 mA/cm(2), and the highest open-circuit voltage of 0.837 V which outperforming other configurations. Turning our attention to X-ray detectors, we find that the same concentration of MoSe2 NS2 works best, producing the highest sensitivity of 2.65 mA/Gy<middle dot>cm(2) and a collected current density of 8.85 mu A/cm(2). These results highlight how versatile MoSe2 NSs are in improving the performance of solar cells and X-ray detectors. MoSe2 NS2 at 5 wt % stands out as a particularly promising configuration for effective energy conversion and X-ray sensing applications.
