Natural dye from Argemone mexicana flower is used as the photosensitizer for fabricating dye-sensitized solar cells (DSSCs). The cells were fabricated using TiO₂ as the semiconducting layer deposited on the transparent fluorine-doped tin oxide (FTO) conductive glass. Microwave processing is used for annealing the TiO₂-coated FTO glass. The UV–Vis absorption spectra, FTIR and Raman Spectral studies were carried out to check the suitability of the dyes. The I–V characteristic curves of all the fabricated DSSCs were measured and analyzed. The photovoltaic parameters, short-circuit current (I_sc), open-circuit voltage (V_oc), fill factor (FF) and efficiency (η) of microwave annealed DSSCs are calculated and reported in this paper. Optimum values were observed for solar cells prepared with blocking layer and irradiated with microwave for 7 min, short-circuit current = 2.71 mA, open-circuit voltage = 0.47 mV, fill factor=0.54 and efficiency = 0.69.

来自Argemone mexicana花的天然染料用作制造染料敏化太阳能电池 (DSSC) 的光敏剂。电池是使用 TiO ₂作为半导体层制造的，沉积在透明的掺氟氧化锡 (FTO) 导电玻璃上。微波处理用于对涂覆有TiO ₂的FTO玻璃进行退火。进行紫外-可见吸收光谱、FTIR 和拉曼光谱研究以检查染料的适用性。测量和分析了所有制造的 DSSC的I - V特性曲线。光伏参数、短路电流（I _sc）、开路电压（V _oc)、微波退火 DSSC 的填充因子 (FF) 和效率 ( η ) 计算并报告在本文中。观察到具有阻挡层的太阳能电池的最佳值并用微波照射 7 分钟，短路电流 = 2.71 mA，开路电压 = 0.47 mV，填充因子 = 0.54 和效率 = 0.69。
