“…For the optimized Dev 3, the values of the three parameters V OC , FF, and PCE decrease with increasing temperature from 300 to 400 K. The values of V OC , FF, and PCE are identified as 0.982 V, 85.01%, and 30.10%, respectively, for Dev 3 at 300 K, but the value of the parameter J SC for Dev 3 remains nearly unchanged with a value of 31.89 mA/cm 2 as the temperature increases. When the temperature reaches 400 K, the values of J SC , V OC , FF, and PCE become a minimum, and the values are estimated as 31.94 mA/cm 2 , 1.081 V, 80%, and 27.51% respectively at 400 K. The current simulation offers an improvement in all the output parameters of Dev 3 with dual active layers as compared to the previous work by Bhattarai et al…”

The present work represents a comparative modeling and performance optimization of three device configurations: ITO/ZnO/Cs2BiAgI6/Spiro-OMeTAD/Au, ITO/ZnO/CIGS/Spiro-OMeTAD/Au, and ITO/ZnO/Cs2BiAgI6/CIGS/Spiro-OMeTAD/Au. The concern of low light absorption by materials such as Cs2BiAgI6 and CIGS limits its application as a light absorber in photovoltaic devices. Nevertheless, the light absorption by the device can be enhanced by the inclusion of a second light active layer composed of the graded active layer of both Cs2BiAgI6/CIGS, which effectively boosts the efficiency of the device configuration. In this study, SCAPS-1D software was employed for analyzing the proposed solar cell models. The optimized output parameters achieved include J SC of 31.89 mA/cm2, V OC of 1.108 V, FF of 85.01%, and PCE of 30.10%, which approaches the Shockley-Queisser limit.

“…Researchers have also discovered the possibility of merging perovskite with quantum dots to increase stability and size compatibility [38][39][40]. Due to perovskite quantum dots (PQDs) comparatively simple synthesis, tunable bandgap and high optical absorption, chances for developing next-generation of optoelectronic devices as well as opportunities for investigating fundamental aspects at the nanoscale unit are created [41][42][43][44]. The best contender among all semiconductors for the creation of a highly efficient solar cell is PQD with a favorable nano-size effect, distinctive multi-exciton generation (MEG), increased phase stability, and exceptional cell hysteresis suppression [45].…”

Perovskite quantum dots (CsPbI3-PQDs), a translucent material, have gained great interest in the PV industries owing to their unified virtues of perovskites and quantum dots. However, researchers have found that perovskite solar cell (PSCs) suffer from issues like low stability at high relative humidity, energy states imbalance, severe hysteresis, and an easy decomposition under ultraviolet (UV) radiation that severely restrict their industrialization. Quantum dots (QDs) are excellent materials with numerous admirable traits that have been extensively employed in PSCs to overcome the aforementioned problems. To achieve high performance of the examined device, the CsPbI3-PQDs has been stacked between two charge transport layers, i.e., Cl@SnO2 (to facilitate electrons towards cathode) and P3HT (to facilitate holes towards anode). In this context, study of variations in different parameters such as thickness and acceptor density of the CsPbI3-PQDs absorber layer has been done. After varying the thickness and acceptor density of the CsPbI3-PQDs layer, the cell’s performance is optimized at thickness of 400 nm and acceptor density of 1×1017/cm3 delivering higher PV parameters power conversion efficiency (PCE):16.17 %, open circuit voltage (VOC):1.02 V, short circuit density (JSC):18.06 mA/cm2 and fill factor (FF): 87.06 % respectively. Thereafter, the effects of bulk defects in CsPbI3-PQDs and the interface between CsPbI3-PQDs and Cl@SnO2 have been explored in this work. For the cell to work at its best, the bulk defect density and interface defect density, respectively, should not be more than 1×1014 /cm3 and 1×1013 /cm2. Afterwards, a comprehensive study has been done by varying the front electrode transparency (from 40% to 95%) to improve the device performance. With 95% of front electrode transparency, the performance of device is improved due to increase in the photon coupling.
