Abstract ：
The optimization of the back interface is an important means of improving the power conversion efficiency (PCE) of Cu2ZnSn(S,Se)4 (CZTSSe) solar cells. Here, a CuO sacrificial layer is introduced into the Mo/CZTSSe back interface to improve device efficiency. The insertion of the CuO sacrificial layer inhibits the formation of Sn(S,Se)2 secondary phases in the CZTSSe film. Meanwhile, the interfacial trap state (N IT) is reduced by about 22%. Furthermore, the 75 nm CuO sacrificial layer can reduce the thickness of the MoSe2 layer, leading to a 33.18 meV reduction in the back interfacial barrier. This design enhances the back interfacial transport characteristics and suppresses defects. Finally, the flexible CZTSSe solar cell achieve the efficiency of 10.57%.

Abstract ：
2D perovskite materials are ideal candidates for indoor photovoltaic (IPV) applications due to their tunable bandgap, high absorption coefficients, and enhanced stability. However, attaining uniform crystallization and overcoming low carrier mobility remain key challenges for 2D perovskites, limiting their overall performance. In this study, a 2D perovskite light-absorbing layer is constructed using a Dion-Jacobson (DJ)-phase EDA(FA)(4)Pb5I16 (n = 5) and introduced butylammonium iodide (BAI) for interface modification, thereby creating a novel DJ/Ruddlesden-Popper (RP) dual 2D perovskite heterostructure. By adjusting the thickness of the BAI-based perovskite layer, the relationship between interfacial defect states and carrier mobility is investigated under varying indoor light intensities. The results indicate that, by achieving a balance between interfacial defect passivation and carrier transport, the optimized 2D perovskite device reaches a power conversion efficiency (PCE) of 30.30% and an open-circuit voltage (V-OC) of 936 mV under 1000 lux (3000 K LED). 2D-DJ/RP perovskite IPV exhibits a twentyfold increase in T-90 lifetime compared to 3D perovskite devices. It is the first time to systematically study 2D perovskites in IPV applications, demonstrating that rationally designed and optimized 2D perovskites hold significant potential for fabricating high-performance indoor PSCs.

Abstract ：
Antimony sulfide (Sb2S3) solar cells fabricated via hydrothermal deposition have attracted widespread attention. The annealing crystallization process plays a crucial role in achieving optimal crystallinity in hydrothermal Sb2S3 thin films. Nevertheless, incomplete crystallization and the loss of sulfur at high-temperature contribute to defect recombination, constraining device performance. Herein, a two-step rapid thermal processing (RTP) annealing strategy is proposed to improve the crystal quality and efficiency of Sb2S3 solar cells. The annealing process in Ar protection with atmospheric pressure can suppress S loss caused by saturated vapor pressure. The two-step RTP annealing with the 330°C low-temperature and 370°C high-temperature process ensures high crystallinity and vertical orientations of Sb2S3 thin films, accompanied by a reduction in defect concentration from 1.01 × 1012 to 5.97 × 1011 cm−3. The Sb2S3 solar cell achieves an efficiency of 8.20% with an enhanced open circuit voltage (VOC) of 784 mV. The build-in voltage (Vbi) of 1.17 V and irradiation-dependent ideal factor (n) of 1.48 demonstrate enhanced heterojunction quality and suppressed defect recombination in the devices. The presented two-step annealing strategy and physical mechanism study will open new prospects for high-performance Sb2S3 solar cells. © Science China Press 2024.

Abstract ：
Antimony sulfide (Sb2S3) photodetectors (PDs) possess extensive application prospects. Efficient carrier transport of a PD significantly affects the detectivity and response speed. Herein, we propose an all-inorganic self-powered Sb2S3 PD based on vertical TiO2 nanorods (NRs). The spray-coated 15-nm TiO2 thin film as a seed layer ensures the growth of compact vertical TiO2 nanorod arrays by the hydrothermal method. One-dimensional TiO2 nanorods facilitate photocarrier separation and transport to enhance device performance. Ultimately, the Sb2S3 PD achieves a responsivity of 0.29 A/W, a specific detectivity of 3.37 x 1012 Jones, and a response time of 7.8 mu s, showing great potential in commercial applications.

Abstract ：
光电探测器能够利用自身结构实现自供电,广泛应用于环境监测、光通信和航空航天等领域,由于硫化锑(Sb_2S_3)无毒、储量丰富、在可见光范围内具有良好的吸光能力,完美符合制备光电探测器的材料要求。因此,我们采用低成本的水热法合成TiO_2纳米棒阵列(NRs),通过快速热蒸发法(RTE)制备Sb_2S_3薄膜。水热法合成的TiO_2-NRs可以增加器件的并联电阻来抑制漏电流。并且可以调控RTE法制备的Sb_2S_3薄膜取向,进而减少链间电荷跳变和复合,有利于光生载流子输运,增强光电响应速度。制备的器件结构为FTO/TiO_2-NRs/Sb_2S_3/Au,可在无外加偏压情况下表现出良好的光电性能,在波长为625 nm、光功率密度为400μW/cm~2的光照条件下,器件的响应度为0.6 A/W,响应时间接近1μs。该Sb_2S_3光伏型探测器将会为光通信提供器件基础。

Abstract ：
物联网行业的发展带动室内能源消耗的提升,光伏电池在室内环境应用的需求也逐步增加。不同于传统户外太阳光照射条件,室内光源针对于人眼设计,主要波长分布在可见光范围,理论计算所得的最佳带隙为1.9 eV~([1]);同时室内环境的光照强度相较于室外弱了2-3个数量级,两者较大的光照条件差异使得老牌的诸如硅基等光伏电池在室内环境的表现并不理想。硫化锑薄膜电池的带隙为1.7 eV,与室内光伏的最佳带隙较为匹配,同时拥有较大的吸收系数(10~(5 )cm~(-1))~([2]),针对于弱光环境实现一个良好的吸光效果,是一种可应用于室内光伏的优秀材料。在常用的室内照明用台灯的照射下,基础的硫化锑薄膜电池(FTO/TiO_2/Sb_2S_3/Au)实现了1000 lux照度下超过10%的光电转换效率(AM 1.5G下5%)。对于室内光照的特定环境,再针对硫化锑薄膜电池进行带隙提升、界面改性等处理,有望实现在室内弱光环境下的更高光电转换效率~([3])。

Abstract ：
Efficient ternary organic solar cells were achieved by utilizing an ultra-narrow bandgap material, IEICO-4 F, mixed with the fullerene material PC71BM as the acceptor and PTB7-Th polymer as the donor. The different weights of IEICO-4 F were dropped into the active layer to adjust the ratio of acceptor and donor, optimizing the performance of the cells. The results showed the ternary organic solar cells with 10wt% IEICO-4 F could obtain a higher short-circuit current density resulting in the power conversion efficiency (PCE) up to 9.56%. MoO3/Ag/MoO3 as the transparent electrodes of the semitransparent organic solar cell (ST-OSCs) were prepared. The different thicknesses of Ag impacts on the performance of the ST-OSCs were investigated. The PCE of the ternary ST-OSCs was increased to 7.34% and the average visible light transmittance (AVT) was increased to 28.74% when Ag was 10 nm thickness. The ternary ST-OSCs presented both a good light transmittance and a high PCE. In addition, the light utilization efficiency of the ST-OSCs was increased to 2.1%, and the color reproduction index was improved too. The PCE and AVT of the ST-OSCs could improve simultaneously due to the appropriate ratio of the acceptor and donor as well as the optimized transparent electrodes.

Abstract ：
Antimony selenosulfide (Sb-2(S,Se)(3)) solar cells have achieved an efficiency of over 10.0%. However, the uncontrollable hydrothermal process makes preparing high-quality Sb-2(S,Se)(3) thin films a bottleneck for efficient Sb-2(S,Se)(3) solar cell. To address this problem, triethanolamine (TEA) additive is innovatively utilized to regulate the reaction kinetic process of Sb-2(S,Se)(3) thin films in this work. The results show that TEA chelator can realize the time-domain control of the reaction process, optimizing the Se/(S+Se) elemental distribution of Sb-2(S,Se)(3) thin film and shrinking the bandgap offset of Sb-2(S,Se)(3) thin film. Meanwhile, the (021) and (061) crystal orientation of Sb-2(S,Se)(3) thin film are enhanced and the harmful V-Se1 defects in Sb-2(S,Se)(3) solar cells are passivated. Interestingly, a uniform back surface gradient for Sb-2(S,Se)(3) thin film is formed to reduce the minority carrier recombination at the back contact, increase the photocurrent and decrease the diode current of Sb-2(S,Se)(3) solar cells. Finally, the J(sc) and FF of Sb-2(S,Se)(3) solar cells are significantly improved by 8.6% and 5.5% respectively, and the open-circuit voltage deficit of the device is reduced by 44 mV, which leads to an efficiency of 9.94% which is the highest values of Sb-2(S,Se)(3) solar cells by sodium selenosulfate system.
