The management of solar conversion by exploiting a wider regime of the solar spectrum was a key feature of many photovoltaics studies.¹ Spectral downshifting of highly energetic photons in the ultraviolet region was introduce previously in Luminescent solar concentrator technology to decrease the effect of thermalization in Si-related solar cells. Furthermore, the antireflection coating was used to decrease sunlight losses on the Si surface. Herein, we introduce novel hybrid organic (PEDOT: PSS)/inorganic (silicon nanotip) solar cells combined with Mn-doped CsPbCl₃ perovskite nanocrystals (NCs). This is the first report for the application of highly luminescent Mn-doped CsPbCl₃ perovskite NCs as downshifting functional materials. NCs of Mn doped CsPbCL₃ act as a radiative and nonradiative energy transfer centers.² This new energy transfer mechanism drastically enhanced the energy conversion efficiency from 10.6% to 13.4%.² The realization of highly efficient perovskite-based hybrid solar cells shows the potential application for the production of high efficiency, large-area, cost-effective and commercially feasible cell.
