Summary: This study investigates the impact of spontaneous and piezoelectric polarization on carrier dynamics in InGaN/GaN solar cells. Numerical simulations comparing structures with N-face and Ga-face polarity were conducted. The optimal device structure was identified by studying the dependency of device performance on indium fraction and non-radiative center density.

Summary: An efficient substrate-configuration p-i-n metal-halide perovskite solar cell is fabricated on a polymer-coated steel substrate. The optimized cell structure reaches a conversion efficiency close to that of the reference cell. The major optical losses come from several layers in the cell, especially the top ITO electrode and C60 layer.

Summary: Using the InGaN/GaN quantum wells model system, this study investigated the interfacial polarization and its synergic effect with the built-in electric field in solar cells. The generated polarized electric field was consistent with the built-in electric field on different surfaces, favoring electron-hole separation efficiency. Additionally, high-quality InGaN/GaN quantum wells were successfully grown on a specific surface. This atomic-scale investigation provides a fundamental understanding of the polarization-induced electric field and its interaction with the built-in electric field, applicable to polar material-based solar cells.

Summary: Through numerical simulation studies, it was found that interface defects have a significant impact on the performance of heterojunction solar cells, and increasing the bandgap of the absorber layer can improve the performance of the solar cells. Compared to n-TiO2/p-Cu2O heterojunction solar cells, n-TiO2/p-WS2 heterojunction solar cells showed an increase in performance of nearly 182%, and the performance was further enhanced by about 139% with the addition of a p-Cu2O hole transport layer. The best-simulated efficiency of the proposed hetero-structure solar cell was 28.86%.

Summary: Daily temperature variations challenge the stability of halide perovskites in solar cells. However, by using the ordered dipolar structure of beta-poly(1,1-difluoroethylene), we were able to stabilize the perovskite black phase and improve solar cell performance. Our p-i-n perovskite solar cells achieved a record power conversion efficiency of 24.6% and retained high efficiency after exposure to various temperatures and thermal cycling.

Summary: In this paper, a model based on material parameters and equations is proposed to describe the quantum efficiency of InGaN/GaN MQW solar cells. The study demonstrates that the proposed model can effectively reproduce the spectral response of the cells. Additionally, it is found that the p-GaN layer absorbs radiation, but the carriers generated in this region do not significantly contribute to device current.
