Abstract: ABSTRACT “A RADIATIVE COOLING FILM FOR A SOLAR CELL” The present invention relates to a radiative cooling film for a solar cell comprising of a flexible polymer substrate, polyethylene terephthalate (PET) substrate, and a stack of multilayers arranged in 14 alternating layers from top to bottom, where the radiative cooling film allow more incident photons to reach the perovskite, increasing absorbance and resulting in an absolute efficiency enhancement of 1.07%, integrating passive radiative cooling with selective reflection in the sub-bandgap wavelength range that reduces the calculated operating temperature by approximately 10°C, improving the absolute efficiency by 2.69%, thereby yielding a combined absolute power conversion efficiency enhancement of approximately 3.76%. Figure 1 on sheet no. 1 of the drawings may accompany the abstract when published.
