Abstract:
The time dependences of the key characteristic of $a$-Si:H solar cells over daylight hours are theoretically simulated. The model is used to calculate the time dependences for an arbitrary geographic latitude in the interval 30$^\circ$–60$^\circ$ and arbitrary day of the year. The calculated results are illustrated for a geographic latitude of 45$^\circ$ and equinox. The relative variations in the characteristics of the $a$-Si:H solar cells are valid with a relatively high accuracy for the solar cells based on alternative semiconductors provided that their efficiency ranges form 7 to 20%.
