The perovskite solar cells (PSCs) paved the way towards cost-effective and high-performance PV technology. High absorption coefficients, high electron and hole mobilities, and long charge carrier diffusion lengths are the key parameters attributed to highly efficient PSCs [ 3 ].
The progressive increase in the power conversion efficiency (PCE) of solution-processed perovskite solar cells (PSCs) (1, 2) has been enabled in part by strategies to passivate the grain boundaries and interfaces between the perovskite absorber and the charge transport layers (3 – 9).
On the other hand, the operating mechanics of silicon solar cells, DSCs, and perovskite solar cells differ. The performance of silicon solar cells is described using the dopant density and distribution, which is modelled as a p-n junction with doping. The redox level in electrolytes impacts the output voltage of a device in DSCs.
Each component layer of the perovskite solar cell, including their energy level, cathode and anode work function, defect density, doping density, etc., affects the device's optoelectronic properties. For the numerical modelling of perovskite solar cells, we used SETFOS-Fluxim, a commercially available piece of software.
As a result, we observe a net gain in the device V OC reaching 1.21 V, the highest value reported to date for highly efficient perovskite PVs, leading to a champion efficiency of 24%. Modeling depicts a coherent matching of the crystal and electronic structure at the interface, robust to defect states and molecular reorientation.
