The influence of ambient light spectrum (LED, INC, CFL, Xenon…) on the efficiency of perovskite indoor photovoltaic solar cells for Internet of Things (IoT) applications

Perovskite solar cells PSCs show excellent performance for outdoor applications; Nevertheless, they hold significant potential for application under artificial lighting. However, both experimental and theoretical research about the use of PSCs for indoor light harvesting remain overlooked. In this work, a PSC has been designed as FTO/TiO2/MAGeI3/Spiro-OMeTAD and investigated under air mass 1.5G light (Sun), LED light, and Incandescent light (INC), Compact Fluorescent Light (CFL), Flashlight, and Xenon illumination employing SCAPS-1D. Initially, the efficiency is 15.47 % 34.23 % 15.01 % 33.92 % 32.40 % 21.40 % under Sun, LED, INC, CFL, Flash, Xenon, respectively. After that, the effect of the thickness and bap gap of the MAGeI3 absorber under the studied ambient lights has also been studied and reached 16.09 % 36.09 % 17.8 % 35.25 % 35.17 % and 22.92 % as a PCE, respectively. This inspection of MAGeI3-based perovskite for indoor application supports the deployment of indoor PSCs for Internet of Things devices.
