“…This makes PPA an excellent candidate for performing a comprehensive investigation of PHS as a function of both temperature and light intensity, as it has potential to uncover a complex behavior that can eventually lead to a better understanding of this important phenomenon. In addition, the investigation of PHS over a wide range of temperature and illumination intensities is important as the solar cells operating outdoors will be exposed to a wide range of conditions and those operating indoors (perovskite solar cells are particularly promising for indoor applications , ) are operating at significantly lower illumination intensities compared to 1 sun (100 mW/cm 2 ).…”

Photoinduced halide segregation (PHS) is a process of critical importance for the performance of perovskite solar cells with mixed halide absorber layers. However, PHS is still not well understood, especially in the case of layered mixed halide perovskites (MHPs), which are less commonly studied compared to their 3D counterparts. Here, we investigated temperature-and light-induced PHS in 2D MHPs with a phenylpropylammonium (PPA) spacer. We found that 2D PPAbased MHPs exhibited complex segregation behavior dependence on temperature and illumination intensity with the suppression of segregation observed at high temperature (attributed to the highly exothermic nature of the process) as well as moderate illumination intensities, illustrating the importance of additional processes present in this particular material, which exhibits distinctly different behavior compared to 2D MHPs with other aromatic cations.

“…The device without encapsulation was measured in controlled dry-air conditions (20 °C, RH ∼ 5%) at the maximum-power points with bias voltages of 0.925 and 1.043 V, respectively. To the best of our knowledge, the champion f-PSC achieved the highest PCE reported to date for f-PSCs under these specific illumination conditions . In addition, the weight of the 2 × 2 cm 2 f-PSC (0.071 g) was 16 times lighter than that of the glass-based PCS (1.145g), as shown in Figure S22a–d.…”

Van der Waals Force-Assisted Heat-Transfer Engineering for Overcoming Limited Efficiency of Flexible Perovskite Solar Cells

et al. 2022

Flexible perovskite solar cells (f-PSCs) have attracted increasing attention for a variety of applications because of their desirable form factor and improved durability. However, the f-PSC fabrication process has not been optimized, resulting in their uneven efficiency. We report a van der Waals stacking (vdWS) process that yields uniform and highly crystalline perovskite films on flexible substrates by uniform heat transfer during the perovskite annealing process. In addition, the surface and grain boundary defects on the perovskite film were effectively minimized with the vacuum-assisted passivation post-treatment; accordingly, the environmental and mechanical stabilities of f-PSCs were enhanced. Also, the best f-PSC with an active area of 0.14 cm2 achieved power conversion efficiencies (PCEs) of 41.23% and 22.54% under 1000 lx and 1 sun illuminations, respectively. Furthermore, the vdWS process showed scalable uniformity through flexible perovskite solar minimodules with a certified PCE of 18.35% in an active area of 48.90 cm2.

“…[48][49][50][51][52] Therefore, despite revealing high performance under various ambient light intensity conditions, these traditional device configurations raise concerns about achieving the stable and infinite functioning lifetime expected for futuristic self-powered electronic devices, IoT, and sensor applications. [6,[53][54][55] Contrary to these traditional configurations of PSC technology, hole-conductor-free carbon-based triple mesoscopic printable perovskite solar cells (CPSCs) [56,57] offer unique opportunities including low cost of fabrication with established scalable methods such as screen-or inkjet-based printing techniques. [58,59] Moreover, their robust and long-term PV operational stability outperforms other reported traditional device configurations of PSC technology, as frequently proven under various simulated and natural environmental conditions since they were first reported.…”

Energy harvesting technologies collect various forms of ambient energies such as heat, light, or vibrations to generate electricity at micro scales. [1,2] Provided that the wasted energy dissipated in the environment is ubiquitous, energy harvesters present the potential to be self-sustaining with an ideal infinite functioning lifetime. Therefore, they have been considered a potential alternative to the traditional battery-based energy solutions presently enforced to energize electronic consumer goods, the Internet of Things (IoT), or other distributed electronic-based ecosystems. [3,4] Since many of these electronic devices are typically located inside buildings, there is great potential for energizing them via integrating photovoltaics (PVs) that can harvest abundantly available ambient indoor light energy from LED, halogen, and FL lamps or other types of light sources. This promising approach can be used to achieve sustainability within portable electronic devices, as well as in advanced-distributed electronic environments. [3,[5][6][7][8][9] Keeping this motivation in mind, established silicon (Si) solar cell-based PV technologies have initially been deployed to harvest ambient light energy for energizing various low-powered electronic appliances such as calculators, digital thermometers, and electronic clocks. [10] However, the low power conversion efficiency under lowlight conditions, combined with high production costs have limited their widespread use in indoor applications. [7,8,11] In contrast to Si-based PVs, third-generation-based solar cell technologies such as organic solar cells (OSC) or dye-sensitized solar cells (DSSC) have shown striking performance with higher conversion efficiencies when tested under indoor light conditions. [12][13][14][15][16][17][18][19] Similar to these third-generation-based PV technologies, the escalating conversion efficiencies of perovskite solar cells (PSCs) under standard illumination conditions [20,21] consequently motivated research labs worldwide to also examine their PV performance under various ambient light intensities. [6,[22][23][24][25][26] As expected, the striking conversion efficiencies of PSCs achieved in recent years (Table 1) under these ambient light intensity conditions provide preliminary evidence for considering them as another potential light-harvesting solution for energizing
