Perovskite materials offer a great potential in the application of semitransparent solar cells, owing to the tunable bandgap, ease of preparation and excellent photovoltaic property. A majority of works exhibit high average visible‐light transmittance (AVT) for semitransparent perovskite solar cells (ST‐PSCs) through decreasing perovskite thickness, leading to sacrificing the power conversion efficiency (PCE) of the device. Herein, a wide‐bandgap (WBG) perovskite of Cs0.2FA0.8Pb(I0.6Br0.4)3 is applied as absorber in ST‐PSCs, which is a tremendous progress to balance both large PCE and high AVT. Moreover, a strategy of simultaneous interfacial modification and defect passivation is provided to enhance the performance of WBG ST‐PSCs. Consequently, an inverted planar structure WBG perovskite solar cell (PSC) achieves 15.06% of PCE with excellent stability by restraining the interfacial energy loss and suppressing the nonradiative recombination. Furthermore, the ST‐PSC obtains high PCE of 14.40% with an AVT of 38% by means of optimizing the transparent electrode. This work provides an efficient and simple method to improve the performance and AVT of ST‐PSCs for the application in building‐integrated photovoltaics.

“…Generally, the optimization of ST-PSCs is evaluated using light use efficiency (LUE = AVT × η × 100). [11] However, the AVT value is more influential than the PCE value because AVT is more likely to have higher values than PCE. Therefore, we suggest the PCE priority LUE (PLUE = AVT × η 2 × 100) value, which yields a figure of merit for ST-PSCs.…”

Transparent electrodes are essential to allow optical transparency for realizing semitransparent perovskite solar cells (ST-PSCs). This study addresses gallium-and titanium-doped indium oxide (IO:GT) between the electron transport layer (ETL) and top electrode to potentially replace conventional indium tin oxide (ITO) used in inverted ST-PSCs. The shallower work function (−4.23 eV) of IO:GT than that (−4.69 eV) of conventional ITO contributes to suppressing the formation of the Schottky barrier and enhancing the charge transport at the ETL/cathode interface. By adopting IO:GT, the ST-PSC exhibits an enhancement in power conversion efficiency (PCE) from 8.59% to 17.90% (certified 17.53%) with an average visible transmittance (AVT) of 21.9%, which is the record PCE at similar AVT among all ST-PSCs reported to date. Moreover, combining these ST-PSCs as the top cell, a four-terminal perovskite-perovskite tandem solar cell is realized, showing a high PCE of 23.35%. Furthermore, the stability of the ST-PSCs is confirmed excellent, maintaining over 96% of the initial PCE after 1864 h (≈77 days) in air ambient without encapsulation, which is better than the device employing a metal cathode. Therefore, these results demonstrate that the adoption of IO:GT can be a promising route for efficient and stable inverted ST-PSCs with preferred transparency.

“…36 Moreover, polymer chains in general are known to reside at the grain boundaries of perovskite domains. [51][52][53] We suspect that the spatial steric bulk and thermal mobility of the polymer backbones of the cellulose derivatives affected the crystal formation of MAPbI 3 , thereby decreasing the average size of the perovskite crystals. 36 Moreover, the average sizes of the crystal grains of the PQ-Cl/MAPbI 3 composite lms were larger than those of the PQ-F/MAPbI 3 and PQ-Br/MAPbI 3 composite lms.…”

“…46,47 The incorporation of ethyl cellulose or cellulose acetate into the perovskite lm can signicantly improve its moisture stability, thermal stability, and photostability by forming hydrogen bonds with MAPbI 3 to stabilize its crystal structure. [51][52][53] Moreover, we expected the quaternary ammonium ions to passivate only the MA + vacancies by occupying cuboctahedral sites, thereby compensating for MA + loss at the surfaces of the perovskite lms. 17 Because the uoride (F À ), chloride (Cl À ), and bromide (Br À ) ions in the quaternary ammonium salts are more electronegative and have smaller ionic radii than iodide (I À ) anions, they form ionic bonds with Pb 2+ cations that are stronger than the Pb-I bonds in perovskite lms.…”
