Solar energy has become crucial in producing electrical because it is inexhaustible and sustainable. However, its uncertain generation causes problems power system operation. Therefore, solar irradiance forecasting significant for suitable controlling operation, organizing the transmission expansion planning, dispatching generation. Nonetheless, performance can be decreased due to unfitted prediction model lacked preprocessing. To deal with mentioned issues, this paper proposes Meta-Learning Extreme Learning Machine optimized Golden Eagle Optimization Logistic Map (MGEL-ELM) Same Datetime Interval Averaged Imputation algorithm (SAME) improving of incomplete time series datasets. Thus, proposed method not only imputing data but also achieving accuracy. The experimental result dataset Thailand indicates that achieve highest coefficient determination value up 0.9307 compared state-of-the-art models. Furthermore, consumes less than deep learning model.

The cosensitization process is an effective way to improve the performance of dye‐sensitized solar cells (DSSCs), especially for tandem that employ complementary light harvest ranges different dyes. Herein, various cosensitized DSSCs are prepared using D35, XY1b, and Y123 dyes employed construct cobalt DSSCs. First, single with without scattering layers studied. results show D35 + XY1b have higher power conversion efficiency (PCE) than others, attributed their longer absorption wavelength charge recombination resistance. Furthermore, cell has significantly open circuit voltage ( V oc ) but slightly lower current density J sc those cell. systems further utilized prepare cells. Photoelectrodes used as top bottom cells, respectively. It shows by (higher sensitizers respectively, a PCE high 36.27% can be achieved under fluorescent lighting. these long‐term stability at room temperature.
