| Summary: | A recent study suggested that the implementation of nanocones, nanotubes, nanorods, and nanopyramids on top of the glass protecting layer of a perovskite solar cell will improve total irradiation by around 3% compared to those of planar cells. However, this study was done under normal light incidence, and the angular dependence of said nanostructured perovskite solar cells was unknown. To estimate the performance of a nanostructured perovskite solar cell, angular dependence is an essential factor since the Sun moves across the sky as the day progresses. This research was aimed to analyze the relationship between the light incidence angle and the total irradiation of the mentioned nanostructures and find the most suitable nanostructure to be used in a perovskite solar cell. This research used a finite-element method using COMSOL Multiphysics software to analyze how the absorption spectrum of nanostructured solar cells was related to the light incidence angle, after which the absorption spectrum was used to calculate the total irradiation of the nanostructured solar cells. The total irradiation of each solar cell was then used to obtain the daily solar energy absorption of each solar cell model. It was confirmed that the total irradiation of each nanostructured perovskite solar cell is higher than that of a planar perovskite solar cell by about 3% at normal incidence. However, this value quickly diminishes as the light incidence angle moves away from normal and becomes lower than that of a planar solar cell on zenith angles above 33°. It was found that planar architecture is the best model for perovskite solar cells as it has the highest daily solar energy absorption value at around 4.2 kWh/m2. However, if a solar tracking system is available for use, nanostructured solar cells can produce the highest daily solar energy absorption since their absorption is higher at low incidence angles. |
