Organic additives in all-inorganic perovskite solar cells and modules: from moisture endurance to enhanced efficiency and operational stability

Out‐of‐Glovebox Integration of Recyclable Europium‐Doped CsPbI3 in Triple‐Mesoscopic Carbon‐Based Solar Cells Exceeding 9% Efficiency

“…For this reason, the perovskite material is not prepared in ambient air but N 2 ‐filled glovebox, [ 13 ] hindering the chances for scaling up and future commercialization. To overcome this issue, different strategies have been implemented like the use of dopants [ 14 ] (organic, inorganic, elemental doping) in the CsPbI 3 precursor solution which improves the morphological and structural properties of the CsPbI 3 thin film, [ 15 ] resulting in better stability in air and enhanced device performances.…”

Synergistic Approach toward Erbium-Passivated Triple-Anion Organic-Free Perovskite Solar Cells with Excellent Performance for Agrivoltaics Application

“…Figure 1a shows the statistical view comparing theoretical and practical PCEs for CsPbX 3 -based PSCs attained to date. 42 Hot solution dropping as an optimized protocol can thermodynamically sustain the supersaturation of the precursor solution, which further helps improve the precursor solution's entropy with control over nucleation and crystallization of PAL. Figure 1b illustrates the schematics for pre-heated solution dropping onto an ITO/NiO substrate.…”

Van der Waals Epitaxial Growth for High Performance Organic‐Free Perovskite Solar Cell: Experimental and Theoretical Insights

“…[ 14 ] CsPbIBr 2 with a wide bandgap of 2.03 eV is a nice choice with enhanced phase stability, suitable absorption threshold and its immunity to withstand heat, illumination, and humidity mishmashes, [ 17,18 ] which is also the research focus of this work. As the matter of fact, the highest reported PCE of CsPbIBr 2 is still far away from its theoretical values (17.25%), [ 7,8 ] which is attributed to substantial nonradiative and interface recombination of photo‐enhanced charge carriers. Phase segregation within the perovskite active layer (PAL) is a notorious phenomenon leading to the ionic migration and polaron formation beside the heterojunction of PAL with carrier selective layers (CSL).…”

“…[ 4–6 ] All‐inorganic (CsPbX 3 ) PSCs on the other hand, are comparatively more stable against the degradation entities such as heat, illumination, and moisture, but their PCEs are far from their theoretical values. [ 7,8 ] In general, CsPbX 3 comprised of CsPbI 3 , CsPbI 2 Br, CsPbIBr 2 , and CsPbBr 3 , among them the CsPbI 3 and CsPbI 2 Br have relatively shorter bandgaps of 1.73 and 1.92 eV, respectively. [ 8–10 ] Despite the poor immunity to sustain their cubic structure at room temperature‐humidity ambience, the PCEs are still very attractive for CsPbI 3 (20.37%) [ 11 ] and for CsPbI 2 Br (17.45%).…”
