Nanostructures can be used at the front surface of the solar cell to offer an efficient pathway to couple the incoming light into the absorber layer and thus reduce reflection.
Here we report the first monolithic hierarchical micro/nanostructured perovskite/silicon tandem solar cell with a solution-processed thin perovskite absorber conformally covering the textured silicon surface, showcasing a certified steady-state power conversion efficiency of 30.1% alongside a record fill factor of 84.5%.
Enhancing light absorption and reducing electric loss are the keys to improving the overall conversion efficiency of solar cells and reducing raw material costs. The former can be achieved by using micro/nanostructures and other surface features, while the latter can be realized by surface passivation.
In this review, we discuss some of the recent developments in the design and implementation of nanostructures for light trapping in solar cells. These include the development of solar cells containing photonic and plasmonic nanostructures. The distinct benefits and challenges of these schemes are also explained and discussed.
This study clarifies the mechanism and advantages of common micro/nano structures in photovoltaic devices as well as the synergistic effect of multiple OMNSs, which provides the possibility of customized use of OMNSs for the performance improvement of PSCs and various optoelectronic devices.
Here, the use of plasmonic nanostructures for solar cells should be properly engineered to improve the scattering and reduce the parasitic losses over a broad wavelength range significant for light trapping.
