“…Compared with the absorptance spectrum in fib3b, the EQE shown has a slightly reduced performance from 5 to 10%. On one hand, the ITO/Ag back reflector directed all transmitted light back to the absorbing layer, creating a doubled or even multiplied light propagation length which favors the absorption 48 . On the other hand, parasitic absorptions of top ITO and ITO/Ag back reflectors brought down the performance 37 .…”

Photon management strategies are crucial to improve the efficiency of perovskite thin film (PTF) solar cell. In this work, a nano-cone (NC) based 2D photonic nanostructure is designed and simulated aiming at achieve superior light trapping performance by introducing strong light scattering and interferences within perovskite active layer. Compared to the planar PTF solar cell, the NC nanostructured device with 45 degrees half apex angle obtains highest short-circuit current density, which improved over 20% from 15.00 mA/cm2 to 18.09 mA/cm2. This work offers an alternative design towards effective light trapping performance using 2D photonic nanostructure for PTF solar cell and could potentially be adopted as the nano-structuring strategy for the future perovskite solar cell industry.

“…The performance is compared with that of a standard PSC configuration with metallic back reflector (MBR). Similar studies [27,28] have explored the use of LBR in MAPbI 3 PSCs in the standard n-i-p configuration combining Monte-Carlo technique and transfer-matrix method to model the diffuse and coherent light propagation respectively. We extend these works to explore optimization in both n-i-p and p-i-n (inverted) structures, and also study the effect of photon recycling in these cells.…”

In this study, the effectiveness of a Lambertian back reflector for trapping light in a MAPbI3 perovskite solar cell has been investigated. The propagation of collimated and diffuse light in the cell has been modelled using the transfer-matrix method and the radiative transfer equation respectively. We show that in the presence of such a reflector, the population of tail states at wavelengths beyond the band-edge of a conventional cell can be substantially increased. As a result of this enhanced light absorption, the power conversion efficiency of a 600 nm thick active layer in a conventional n-i-p (p-i-n) cell is shown to be attainable with a reduced thickness of 300 nm (200 nm) in the presence of light trapping. The effect of photon recycling to increase the open circuit voltage in these structures has also been studied for different thicknesses of the active layer. An increased open circuit voltage in the range 125-145 mV is observed for a Lambertian back reflector as compared to155-170 mV increase seen in a conventional cell with metallic back reflector.
