Design and Simulation of ETL-Free Perovskite/Si Tandem Cell with 33% Efficiency

Abstract

Multi-junction (tandem) cell using MAPbI3-xClx and silicon as absorbers has been designed and simulated in this paper. The thickness of the silicon layer in the bottom cell is 2 μm allowing it to absorb the transmitted spectrum from the perovskite subcell as much as possible. The thickness of the MAPbI3-xClx layer is optimized using a proposed algorithm. The output metrics show that the optimum thickness of the MAPbI3-xClx layer was 205 nm. The simulation outputs showed that the proposed tandem cell has an efficiency of 33.09% with an open circuit voltage of 1.9 V and a short circuit current of 19.95 mA/cm2 .

Large-Scale Rooftop Solar Photovoltaic Power Production Potential Assessment: A Case Study for Tehran Metropolitan Area, Iran

“…Here, we consider the most widely used PV technology, a standard 60-cell mono-crystalline silicon panel with a size of 1.63 m 2 , which has a cell efficiency of 22.9% and a rating power of 300 W. There are different technologies with various cell efficiency values ranging from above 40% to 12%. We chose a commonly used type of PV module for this potential assessment task [44]. However, the panel efficiency was assumed to be C PVe f f = 0.22 to be on the safe side.…”
