Solar cells have attracted much attention since they can convert solar energy directly into electricity, and have been widely utilized in manufacturing industry and people's daily life. Although the power conversion efficiency (PCE) of single-junction solar cells has gradually improved in recent years, its maximum efficiency is restricted by the Shockley-Queisser (SQ) limit of single-junction solar cells. To exceed the SQ limit and further obtain high efficiency solar cells, researchers have proposed the concept of tandem solar cells. In this work, a systematic theoretical study of chalcopyrite CuGaSe2/CuInSe2 tandem solar cells was carried out by combining first-principle calculations and SCAPS-1D device simulations. Firstly, the electronic structure, defect properties and corresponding macroscopic performance parameters of CuGaSe2 (CGS) were obtained by first-principles calculations, which were adopted as input parameters for subsequent device simulations of CGS solar cells. Subsequently, the simulations of single-junction CGS and CuInSe2 (CIS) solar cells were carried out using SCAPS-1D software, respectively. The simulation results for the single junction CIS solar cells are in good agreement with the experimental values. For single-junction CGS cells, the device simulations revealed that CGS single-junction solar cells had the highest short-circuit current (Jsc) and PCE at the growth condition of Cu-rich, Ga-rich and Se-poor chemical growth condition. Further optimization found that the open-circuit voltage (Voc) and PCE of CGS solar cells can be improved by replacing the electron transport layer (ETL) with ZnSe after the devices with the highest short-circuit current (Jsc). Finally, after the optimized CGS and CIS solar cells were connected in series with two-terminal (2T) monolithic tandem solar cell, the device simulation results show that under the growth temperature of 700 K and the growth environment of Cu-rich, Ga-rich, and Se-poor, with ZnSe as the ETL, the CGS thickness of 2000 nm and the CIS thickness of 1336 nm, the PCE of 2T monolithic CGS/CIS tandem solar cell can reach 28.91 %, which is higher than the recorded efficiency of the current single-junction solar cells, and shows a good application prospect.

“…The PCE of single-junction PSCs utilizing perovskites as photosensitive layers have witnessed a rapid ascent, escalating from an initial 3.85% to the current 26.14% . The wide-bandgap PSC is an ideal candidate top cell for tandem solar cells, but as present suffers from large open-circuit voltage loss. − To this end, diverse methods such as additive engineering, − passivation engineering, − and component manipulation − have been employed to enhance film morphology. Nevertheless, the precise regulation of perovskite crystallization kinetics remains challenging due to the inherent randomness in nucleation and disordered diffusion growth during spontaneous solution chemical reactions …”

The seed method stands out as a straightforward and efficient approach for fabricating high-performance perovskite solar cells (PSCs). In this study, we propose the utilization of an antisolvent as an additive to induce crystal seeding, thereby facilitating the growth of wide-bandgap perovskite grains. Specifically, we introduce three commonly used antisolvents�ethyl acetate (EA), isopropanol (IPA), and chlorobenzene (CB)�directly into the perovskite precursor solution to generate perovskite seeds, which serve to promote subsequent nucleation. This antisolvent−crystal seeding method (ACSM) results in increased grain sizes, reduced film defects, and overall improved film quality. Consequently, the power conversion efficiencies (PCEs) of 1.647 eV PSCs with EA, IPA, and CB additives are recorded at 19.86%, 20.61%, and 20.45%, respectively, surpassing that of the reference device with a PCE of 18.83%. Furthermore, the stability of the PSCs prepared through ACSM is notably enhanced. Notably, PSCs optimized with IPA retain 75% of the original PCE after being stored in ambient air conditions (25 °C, RH ∼ 15%) for 30 days, better than the CB-added (64%) and the EA-added devices (53%), while the reference devices only retain 31% of the initial PCE. Moreover, even after continuous thermal annealing at 50 °C for 200 h, IPA-assisted devices demonstrate the best stability, followed by those with CB and EA, with the reference exhibiting the poorest stability.

Developing high‐quality wide bandgap (WBG) perovskites with ≈1.7 eV bandgap (Eg) is critical to couple with silicon and create efficient silicon/perovskite tandem devices. The sufferings of large open‐circuit voltage (VOC) loss and unstable power output under operation continuously highlight the criticality to fully develop high‐quality WBG perovskite films. In this study, rubidium and thiocyanate as additive regulators in WBG perovskites are incorporated, significantly reducing non‐radiative recombination, ion‐migration, and phase segregation. The optimized 1.66 eV Eg perovskite solar cells achieved state‐of‐art 1.3 V VOC (0.36 V deficit), and delivered a stabilized power conversion efficiency of 24.3%, along with good device stability (20% degradation (T80) after over 994 h of operation under 1 sun at ≈65°C). When integrated with a flat front side silicon cell, silicon/perovskite two‐terminal tandem device (30% efficient) is obtained with a 1.97 V VOC, and T90 operational lifetime of more than 600 h at room temperature.
