Abstract Following the 2nd release of “Emerging PV reports,” best achievements in performance emerging photovoltaic devices diverse research subjects are summarized, as reported peer‐reviewed articles academic journals since August 2021. Updated graphs, tables, and analyses provided with several parameters, e.g., power conversion efficiency, open‐circuit voltage, short‐circuit current density, fill factor, light utilization stability test energy yield. These parameters presented a function bandgap average visible transmittance for each technology application, put into perspective using, detailed balance efficiency limit. The 3rd installment reports” extends scope toward triple junction solar cells.

Tin halide perovskites are promising materials for real-world photovoltaic applications, and there is large room their performance to grow. We improved energy-level alignment between the perovskite electron transport layers by introducing 4-fluorophenethylamine hydrobromide as an interfacial dipole. Thus, open-circuit voltage of FASnI3 solar cells increased 0.974 V power conversion efficiency reached 15.7%, representing a significant advance in this field.

Abstract Tin halide perovskite solar cells (TPSCs) have attracted aggressive research interest in the emerging photovoltaic devices due to their eco‐friendliness as compared lead counterparts. However, easy Sn(II)/Sn(IV) oxidation of tin perovskites is a serious impediment development TPSCs. Therefore, clear understanding mechanisms, origins, and effects essential further boost performance stability Herein, systematic overview physicochemical process for TPSCs from starting precursors final presented. In addition, on are then reviewed crystal structure, defect chemistry, optoelectronic properties. More importantly, key issues suppress seriously discussed basis reported antioxidation strategies. Finally, challenges outlooks toward with higher power conversion efficiency proposed.

Abstract Sn perovskite solar cells have been regarded as one of the most promising alternatives to Pb‐based counterparts due their low toxicity and excellent optoelectronic properties. However, perovskites are notorious feature heavy p‐doping characteristics possess abundant vacancy defects, which result in under‐optimized interfacial energy level alignment severe nonradiative recombination. Here, we reported a synergic “electron defect compensation” strategy simultaneously modulate electronic structures profiles via incorporating traced amount (0.1 mol %) heterovalent metal halide salts. Consequently, doping modified was altered from p‐type weak (i.e. up‐shifting Fermi by ∼0.12 eV) that determinately reducing barrier charge extraction effectively suppressing recombination loss throughout bulk film at relevant interfaces. Pioneeringly, resultant device with electron compensation realized champion efficiency 14.02 %, is ∼46 % higher than control (9.56 %). Notably, record‐high photovoltage 1.013 V attained, corresponding lowest voltage deficit 0.38 eV date, narrowing gap analogues (∼0.30 V).

Abstract Four X‐shaped quinoxaline‐based organic dyes, PQx (1), TQx, (2), PQxD (3), and TQxD (4) (D = dye sensitizers) are developed served as p ‐type self‐assemble monolayer (SAM) for tin perovskite solar cells (TPSC). Thermal, optical, electrochemical properties of these SAMs thoroughly investigated characterized. Tin layers successfully deposited on four SAM surfaces according to a two‐step approach the devices exhibit power conversion efficiency in order (8.3%) > TQx (8.0%) (7.1%) (6.1%). With thiophene π‐extended conjugation unit structure, exhibits highest hole extraction rates, greatest mobilities, slowest charge recombination achieve great device performance 8.3%, which is current best result SAM‐based TPSC ever reported. Furthermore, all except shows enduring stability retaining ≈90% their original values shelf storage over 1600 h.

Abstract Tin halide perovskites have the general chemical formula ASnX 3 , where A is a monovalent cation and X anion. These semiconducting materials can be used to fabricate p-type transistors at low cost temperature could potentially integrated with n-type oxide-based create complementary circuits. However, suffer from crystallization controllability high film defect density, resulting in uncompetitive device performance. Here we show that pure-tin perovskite thin-film created using triple cations of caesium–formamidinium–phenethylammonium. The approach leads high-quality cascaded tin channel films low-defect, phase-pure perovskite/dielectric interfaces. optimized exhibit hole mobilities over 70 cm 2 V −1 s on/off current ratios 10 8 which are comparable commercial low-temperature polysilicon transistors. fabricated solution-processing methods temperatures no higher than 100 °C.
