Here, we have proposed some ways to enhance the efficiency of Perovskite colloidal quantum dots (PCQDSCs). At first, we have modeled experimental J–V results from a valid reference, and we examined our proposal. For the achievement of the highly efficient PCQDSCs, different materials as electron and hole transport layers (ETLs and HTLs) are replaced in the validated solar cell device, and efficiency enhancement was seen for ZnO and NiO as ETL and HTL, respectively. In the real situations, may be our results are not reliable and it’s due to the interface effect that can be considered by the interface properties of these mentioned materials with other semiconductor materials in the device. For considering this effect, we have modeled the validated case by changing the interface properties such as surface defect density, electron–hole capture cross sections, defect energy level, and surface defect types. The results show that choosing materials such as ETLs and HTLs with the formation of good interfaces with absorber and buffer is necessary to achieve highly efficient PCQDSCs. The results were promising and show that the PCQDSCs can be achieved 21.39% efficiency which is very high and eager the researchers work on it using the PCQDSCs in industrial applications.
