The film quality of the electron transport layer (ETL) plays an important role in improving the performance of perovskite solar cells (PSCs). In order to reduce the effect of rough fluorine-doped SnO2 (FTO)substrate on the film quality of the TiO2 ETL, multiple cycles of spin-coating were employed to realize optimized TiO2 film and improve the performance of PSCs with rough FTO. The results show that TiO2 ETL was optimized most effectively using two spin-coating cycles, obtaining the best performance of PSCs with rough FTO. The carbon electrode-based PSCs were then demonstrated. Our work discusses the feasibility of low-quality rough FTO for the fabrication of PSCs and photodetectors to reduce costs.

“…An extensive study using several methods on a single-junction GaAs cell was conducted by Papež et al, which dealt with the degradation of GaAs cells over the past few years. Degradation after thermal processing [ 70 , 71 ], after cooling [ 6 ], after exposure to gamma radiation [ 50 , 72 ], and after exposure to broadband radiation was studied [ 73 ]. An unstressed sample was also observed, and defects and contamination after fabrication were examined [ 74 ].…”

“…The occurrence of surface defects and an evident change in morphology were obvious in Figure 9 . However, it can be expected that the loss of solar cell performance is not only caused by a different surface structure but also by internal degradation processes [ 70 , 71 , 75 ].…”

As widely-available silicon solar cells, the development of GaAs-based solar cells has been ongoing for many years. Although cells on the gallium arsenide basis today achieve the highest efficiency of all, they are not very widespread. They have particular specifications that make them attractive, especially for certain areas. Thanks to their durability under challenging conditions, it is possible to operate them in places where other solar cells have already undergone significant degradation. This review summarizes past, present, and future uses of GaAs photovoltaic cells. It examines advances in their development, performance, and various current implementations and modifications.

This article focuses on processing of data acquired by the atomic force microscopy (AFM) method using tools of MATLAB programming language. The basic examples are presented as codes for two-dimensional (2D) and three-dimensional (3D) images of surface microstructure, heights histograms and S parameters. Furthermore, these examples can be applied to other scanning probe microscopy methods. The advantage of such processing over the software which is supplied to the microscope is complete freedom to work with the obtained data.
