“…The widespread use of renewable energy is essential for achieving carbon neutrality. Photovoltaic (PV) technology, a renewable energy source, experiences increasing power generation each year. , Silicon-based solar cells and modules are the most commercialized in the PV market . Silicon heterojunction (SHJ) solar cells, which belong to the category of silicon-based solar cells, exhibit high open-circuit voltages because of high-quality passivation of crystalline silicon (c-Si) surfaces by intrinsic hydrogenated amorphous silicon (i-a-Si:H) films. − An extremely high conversion efficiency of 26.81% has been recently reported for the SHJ solar cells .…”

High-quality passivation with intrinsic hydrogenated amorphous Si (i-a-Si:H) is essential for achieving highefficiency Si heterojunction (SHJ) solar cells. The formation of i-a-Si:H with a high passivation quality requires strict control of the hydrogen content and film density. In this study, we report the effective discovery of i-a-Si:H deposition conditions through catalytic chemical vapor deposition using Bayesian optimization (BO) to maximize the passivation performance. Another contribution of this study to materials science is the establishment of a practical BO scheme consisting of several prediction models in order to account for the practical constraints. By applying the BO scheme, effective minority carrier lifetime (τ eff ) is maximized within the deposition condition range, while being constrained by the i-a-Si:H thickness and the capabilities of the experimental setup. We achieved a high passivation performance of τ eff > 2.6 ms with only 8 cycles in BO, starting with 14 initial samples. Within the investigated range, the deposition conditions were further explored over 20 cycles. The BO provided not only optimal deposition conditions but also scientific knowledge. Contour plots of the predicted τ eff values obtained through the BO process demonstrated that there is a band-like high τ eff condition in the parameter space between the substrate temperature and SiH 4 flow rate. The high void fraction and epitaxial growth were inhibited by controlling the substrate temperature and SiH 4 flow rate, resulting in a high passivation quality. This indicates that the combination of the SiH 4 flow rate and substrate temperature parameters is crucial to passivation quality. These results can be applied to determine the deposition conditions for a good a-Si:H layer without a high void fraction or epitaxial growth. The research methods shown in this study, practical BO scheme, and further analysis based on the optimized results will be also useful to optimize and analyze the process conditions of semiconductor processes including plasmaenhanced chemical vapor deposition for SHJ solar cells.

Metal halide hybrid perovskites solar cell (PSCs) have received considerable attention over the past decade owing to their potential for low‐cost, solution‐processable, earth‐abundant, and high‐performance superiority, increasing power conversion efficiencies of up to 25.7%. Solar energy conversion into electricity is highly efficient and sustainable, but direct utilisation, storage, and poor energy diversity are difficult to achieve, resulting in a potential waste of resources. Considering its convenience and feasibility, converting solar energy into chemical fuels is regarded as a promising pathway for boosting energy diversity and expanding its utilisation. In addition, the energy conversion‐storage integrated system can efficiently sequentially capture, convert, and store energy in electrochemical energy storage devices. However, a comprehensive overview focusing on PSC‐self‐driven integrated devices with a discussion of their development and limitations remains lacking. In this review, we focus on the development of representative configurations of emerging PSCs‐based photo‐electrochemical devices including self‐charging power packs, unassisted solar water splitting/CO2 reduction. We also summarise the advanced progress in this field, including configuration design, key parameters, working principles, integration strategies, electrode materials, and their performance evaluations. Finally, scientific challenges and future perspectives for ongoing research in this field are presented.This article is protected by copyright. All rights reserved

“…As a representative of renewable and clean energy, solar energy can be effectively exploited and converted into electricity, which has become an ideal source of energy [2] . Since their development in 1970, silicon‐based solar cells have been the most widely researched and used solar cells to date, but their indirect optical bandgap results in the need for a thick active layer for solar energy conversion, thus requiring expensive large‐area materials to manufacture, limiting their scope for practical applications [3,4] . Alternative types of silicon‐based solar cells, such as organic solar cells (OSCs), [5–7] dye‐synthesized solar cells (DSSCs) [8,9] and perovskite solar cells (PSCs), [10–12] have therefore been extensively investigated.…”

As industrial development and over‐consumption of fossil fuel resources lead to an increasing demand for renewable and sustainable energy sources, making solar energy an ideal source of energy. Graphene has attracted much attention in the field of solar cells due to its unique electronic, optical, thermal, and mechanical properties, as well as its high specific surface area, high carrier mobility, and high Young's modulus. In this comprehensive review article, we summarize the theoretical advances of graphene and its derivatives, such as graphene oxide, reduced graphene oxide, graphene quantum dots, hybridized graphene, and graphene doped with heteroatoms, in the field of solar cells. The observed enhancement of solar cell performance due to the incorporation of graphene and its derivatives is explained in detail by first‐principles. The purpose of this paper is to analyze the fundamental mechanisms of the interactions between graphene and its derivatives solar cells through first‐principles to provide theoretical support for their continued development in the field of solar cells, while paving the way for the creation of new strategies to improve solar cell performance and advance the development of sustainable energy technologies.
