Therefore, anti-reflection film with grating has better anti-reflection performance and is appropriate for photovoltaic applications. In addition, grating anti-reflection film prepared by vibration-assisted nanoimprinting can increase the Jsc of solar cells by 4%, from 26.33 mA/cm2 to 27.38 mA/cm 2.
The increase of PCE is explained as a reduction in incident reflection loss by grating anti-reflection film, which promotes the light capture ability of solar cells. Therefore, anti-reflection film with grating has better anti-reflection performance and is appropriate for photovoltaic applications.
This unique property suggests that anti-reflection grating film has an attractive self-cleaning property for Si solar cells. The anti-reflection grating film has superior AR and self-cleaning properties, making it an excellent choice for the AR film.
Photovoltaic (PV) modules are regularly subjected to environmental stressors such as dust build-up and wear from rain and snow.
It is clear that grating anti-reflection film increases Jsc of solar cells from 21.06 mA/cm2 to 26.33 mA/cm 2, indicating that Jsc is increased by 25% while filling factor (FF) and Voc show a small increase. Therefore, the PCE of solar cells with and without grating anti-reflection film are calculated as 6.68% and 8.47%, respectively.
One promising approach involves the application of antireflective coatings to the surface of the photovoltaic glass to improve its transmittance. However, balancing mechanical durability, self-cleaning characteristics, and optical performance for photovoltaic applications remains challenging.
