Pivotal Routes for Maximizing Semitransparent Perovskite Solar Cell Performance: Photon Propagation Management and Carrier Kinetics Regulation

Abstract

Figure 4. a) AVT (black lines) and negative-related J SC (red lines) for a 6 nm thick gold device. The effect of including a 100 nm LiF capping layer is illustrated (dashed lines). Such a capping layer modifies the field distribution inside the device, which affects the average reflected sunlight. Reproduced with permission.

Efficiency improvement of semi-transparent perovskite solar cellsviacrystallinity enhancement

“…According to the definition of LUE (LUE = AVT × PCE), a proper balance between PCE and AVT is essential to achieve high-performance of ST-PSCs. 40 Fig. 5f shows the corresponding relationship graph between LUE and AVT.…”

“…For comparison, the range of LUE values currently available for the entire ST-PSCs devices (including substrates and electrodes) under AM1.5G is 1.5-3.7. [47] Presently, the highest reported LUE is 3.7 [48] for ST-PSCs and 3.5 for ST-OSCs. [49] Furthermore, the partial PCEs of the previously reported ST-PVs were collected and plotted as a function of AVT, as shown in Figure S11 and Table S3 (Supporting Information).…”

Functional Layers of Inverted Flexible Perovskite Solar Cells and Effective Technologies for Device Commercialization

“…Semitransparent FPSCs are ideal candidates for multifunctional integrated buildings and vehicles owing to their excellent visible transparency. [ 225 ] Moreover, semitransparent FPSCs are suitable for the preparation of the top cell in four‐terminal tandem flexible devices due to their translucency and adjustable band gaps. [ 226 ] Therefore, semitransparent FPSCs have broad application prospects in multifunctional integrated devices and tandem flexible devices and are worthy of further study.…”

“…Color rendering index (CRI) and CIELAB color coordinates (a*, b*) are two key parameters for color regulation of semitransparent FPSCs. [ 225 ] Therefore, the above metrics should be comprehensively evaluated before the practical application of semitransparent inverted FPSCs.…”
