TiO2 Composite Films with Nanoparticles and Nanotubes for Efficient Light Harvesting in Perovskite Solar Cells |
초록 |
The flakes of TiO2 nanotube arrays (TiO2 NA’s) have been incorporated into mesoporous TiO2 films in perovskite solar cells and we investigated them for light harvesting. Both normalized reflectance and incident photon-to-current efficiency (IPCE) were increased at longer wavelengths (570–800 nm) by the presence of the flakes of TiO2 NA’s in the cells, implying that the main role of the flakes of TiO2 NA’s is that of light harvesting in perovskite solar cells. We determined that the best energy conversion efficiency of the perovskite solar cells with the flakes of TiO2 NA’s is 15.335%, which occurs for 9wt% the flakes of TiO2 NA’s in a composite layer. This is an improvement of 8.28%, arising from light harvesting, compared to perovskite solar cells without the flakes of TiO2 NA’s. |
