Photon energy loss and management in perovskite solar cells
Energy losses in solar cells intuitively originate from two components: low-energy photons cannot be absorbed, and high-energy photons cannot be effectively utilized (Fig. 1 a). For the former, low-energy photons are not energetic enough to excite effective electron-hole pair generation in the active layer [ 29, 30 ].
