▼ [17a-Z18-7] Efficient Energy Management in Hybrid Organic Silicon Solar Cell by Downshifting using Mn doped CsPbCl3 QDs
Keywords:Si Nanotips, Perovskite, Quantum Dots
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.
