The steady-state integrated power values are 0.63, 0.72, 0.74 and 0.66 for the nanospheres with 0, 1, 3, 5 stacks, respectively. The results indicate that properly increasing the stacking number of nanospheres leads to the maximized enhancement of optical absorption by the solar cell.
Here, we report that boosting radiation in the full device stack is an effective way for reaching the radiative limit of power conversion efficiency (PCE) by demonstrating the correlation between external photoluminescence quantum efficiency (PLQE) of the full device stack and PCE of the devices.
The simulation result agrees with the experimental observation that photocurrents of the InGaN/GaN MQW solar cell is noticeably increased upon the application of stacking PS nanospheres (1–3 layers), leading to the η enhancement of ~31%.
Furthermore, a combination of KFSO and KFPV significantly improved the thermal stability of the device. Our approach represents the cornerstone to effectively boosting radiation of the stacked perovskite layer for achieving the theoretical radiative limit of PSCs.
As a consequence, the ternary APSC with the PPHJ structure obtained a champion efficiency of 17.94%, and also exhibited excellent shelf stability and photostability. Overall, this work reveals that the use of a well-miscible third component can induce orderly D/A stacking, and has great potential for helping create high-performance APSCs.
