Summary: This study introduces a method to calculate the current matching loss of bifacial tandem solar cells through analyzing the current characteristics of bifacial sub-cells, with verification of reliability. Energy yield and loss are predicted for the application of bifacial tandem solar cells in different latitudes, along with possible solutions for increasing yield and reducing costs. The research establishes a base for calculating and predicting the photovoltaic performance of bifacial perovskite/c-Si tandem solar cells.

Summary: In this study, an Au-rGO/TiO2 photoelectrode was fabricated by loading Au nanoparticles and rGO onto TiO2 nanoring-nanotube arrays. The temperature field of Au nanoparticles was simulated and calculated using COMSOL Multiphysics, and the obtained data was further predicted using an artificial neural network model. The predicted results were consistent with the measured temperature rises of the reaction system.

Summary: This article reports an elegant method to integrate perovskites and Si-heterojunction tandem solar cells using an ultra-thin indium tin oxide (ITO) interlayer, which overcomes the efficiency limit of single junction solar cells. It is found that a 1.7 nm ITO interlayer provides efficient interfacing between the silicon and perovskite subcells. Thinner ITO interlayers result in discontinuous films, while thicker ITO interlayers are less effective in localizing shunts.

Summary: Cu2O is introduced to the surface of TiO2 photoelectrode to improve battery performance. The successful deposition of Cu2O on the surface of TiO2 photoelectrode is confirmed, and Cu2O enhances and broadens the absorption and utilization of UV range sunlight by the TiO2 photoelectrode. Electrochemical test results show that the Cu2O-TiO2 photoelectrode possesses a higher carrier concentration under illumination conditions.

Summary: This paper presents a detailed analysis of the energy gain and module design requirements of bifacial HIT-Perovskite tandem cells in globally deployed solar farms. The results show that row-to-row shading significantly affects the efficiency and relative gain of two-terminal tandem cells, and that optimal albedo and design optimization are crucial for maximizing the energy yield potential of fixed-tilt and solar-tracking systems.

Summary: This study demonstrated high-efficiency four-terminal tandem solar cells composed of thin GaAs films stacked onto silicon solar cells, with optimal thickness of the GaAs subcell absorber layer investigated. Tandem cells with different absorber layer thicknesses all showed efficiencies above 30%, with the 2.8 μm absorber layer cell exhibiting the highest efficiency. Optical modeling and equations were utilized to show the enhancement of photon recycling and cell performance due to a low-index glass interlayer.

Summary: The control of surface recombination has been a key factor in improving the efficiency of solar cells in recent years. In this study, a unique heating treatment method called Scanning Zone Annealing (SZA) was used to reduce surface recombination at a TiO2/Si interface, leading to a significant increase in the minority carrier lifetime of the cells. It was found that the thickness of the natively formed SiOx interlayer at the interface could be controlled at the nanometer scale by adjusting the amount of heat transferred during SZA treatment.

Summary: This study presents a two-terminal thin-film tandem solar cell composed of a polymer-based top sub cell and a thin crystalline silicon bottom sub cell. Through calibration against experimental studies, the power conversion efficiency (PCE) of the top sub cell is 9.88% and the PCE of the bottom sub cell is 14.26%. When both sub cells are incorporated into the polymer/Si tandem solar cell, the resulting cell exhibits a PCE of 20.45%. Further optimization of the tandem performance improves the short circuit current density (J(sc)) and PCE to 16.43 mA/cm(2) and 28.41% respectively. Based on TCAD simulation, this all thin-film tandem configuration is feasible for wearable electronics applications.
