Summary: A multi-deposited CdS photoelectrode was prepared by chemical bath deposition process, and it showed significantly higher steady-state photocurrents compared to the single-deposited CdS. This improvement was attributed to the formation of a porous structure, which increased the surface area of CdS and resulted in a thicker deposition on the electrode substrate, causing a redshift of absorption edge and enhancing the photoanodic output.

Summary: Chemical bath deposition (CBD) is commonly used to fabricate SnO2 electron-transport layers in perovskite solar cells. However, long deposition times pose a significant limitation for commercialization. By utilizing ultrasonication, the CBD process can be accelerated without sacrificing coverage. The optimal duration for ultrasonication-assisted CBD was determined to be 30 minutes with current parameters.

Summary: Chemical bath deposition (CBD) is an effective method to fabricate high-quality SnO2 electron transport layer (ETL) for large-area perovskite solar cells (PSCs). However, surface defects on the SnO2 films coated by CBD process have negative impacts on the device performance. In this study, a simple periodic acid post-treatment (PAPT) method is developed to modify the SnO2 layer and improve the energy level alignment between SnO2 and perovskite layers. The PAPT method also inhibits nonradiative recombination and enhances charge transportation, resulting in a champion power conversion efficiency (PCE) of 22.25% for PSCs and 18.10% for perovskite mini-modules.

Summary: The formation of Cd-free Zn1-xSnxOy (ZTO) thin film buffer layers for CIGSe solar cells was studied using chemical bath deposition. By modifying the deposition procedure, flatter ZTO films were obtained with inhibited columnar growth. Increasing the concentration of Sn in the chemical bath resulted in a nontrivial increase in the bandgap. Using a 20% Sn concentration, the CIGSe solar cells achieved similar performance to those with a CdS buffer layer, with a maximum efficiency of 10.4% and an average efficiency of 9%.

Summary: The polycrystalline CdS/CdTe thin film solar cell is an important photovoltaic device for generating solar electricity at a lower cost. The quality of interphases in the CdTe solar cell has a strong impact on its photovoltaic efficiency. Treatment of CdS and CdTe with heat improves the open circuit voltage and efficiency, reducing diffusion of S and Cd. Solar cells with a Te and ZnTe interlayer achieve an efficiency of 12%, with low diffusion of Cu along the absorbent material, creating a stable back contact. Diffusion and intermixing at each junction limit element diffusion in CdTe solar cells.
