Effects of photon recycling and scattering in high-performance perovskite solar cells

Abstract

The contributions of photon recycling and light scattering to the performance of perovskite solar cells are quantified.

Arrays of spherical nanostructured oxide particles for photon management enhancement in photovoltaic devices

“…The absorption in each layer was obtained by the power integral over the entire volume of the observed material layer. 56 As shown in Fig. 4a–c, with reference comparison, the quantitative analysis results are consistent with the above-mentioned trends of the light field interference plots.…”

Nano-optical designs for high-efficiency monolithic perovskite–silicon tandem solar cells

“…Further, the EL emission of perovskite in the nanotextured devices is slightly skewed (Fig. 4c , inset), which might suggest enhanced photon recycling 40 . We note that the implied performance of both silicon subcells is identical and that the efficiency potential obtained with the nanostructured device is almost 32%.…”

Taking a closer look – how the microstructure of Dion–Jacobson perovskites governs their photophysics

“…We attribute this red-shift to the repeated absorption and reemission undergone by waveguided photons that travel laterally (photon recycling) and subsequently become out-coupled at these pinholes or the trenches mentioned above. 21,22 As noted above, these observations can generally also be made when considering a lower magnification. Importantly, though, an insufficient resolution of the small spots creates the impression of bright grains appearing uniformly bright at long wavelengths (Fig.…”
