Abstract: We developed a high-performance photodetector based on (CHNH)SbI (MASbI) microsingle crystals (MSCs). The MASbI single crystals exhibit a low-trap state density of ∼10 cm and a long carrier diffusion length reaching 3.0 μm, suggesting its great potential for optoelectronic applications. However, the centimeter single crystal (CSC)-based photodetector exhibits low responsivity (10 A/W under 1 sun illumination) due to low charge-carrier collection efficiency. By constructing the MSC photodetector with efficient … Show more

“…This shows that the application of perovskite single crystal devices in imaging sensing has a promising prospect. [52][53][54][55] Nanowires and nanorods are also special single crystal structures. However, owing to large specific surface area, defect-free single crystal and high crystal quality.…”

“…[22] Although much higher responsivity and gain can be achieved in PDs by introducing heterostructures in the devices, [22][23][24][25] the additional processing steps and materials involved in the devices may complicate the fabrication procedure and increase the cost. [27][28][29][30][31] For instance, Waleed et al fabricated a MASnI 3 nanowire-array PD by using a vapor phase chemical reaction method with porous alumina template, exhibiting a responsivity and detectivity of only 0.47 A W −1 and 8.80 × 10 10 Jones, respectively. [26] In light of this, some works have been done on lead-free perovskite-based PDs, yet satisfactory results are still lacking.…”

“…The preferred formation of 0D and 2D structure depends on the sample preparation technique as well as an addition of additives ,,. The bulk phase of Sb based perovskites are explored in the specific form of Cs 3 Sb 2 Cl 9 (hexagonal P321), Cs 3 Sb 2 Br 9 (trigonal P3m1 ), MA 3 Sb 2 I 9 (hexagonal P 6 3 / mmc ), MA 3 Sb 2 Br 9 (trigonal P3m1 ) and (NH 4 ) 3 Sb 2 I x Br 9− x (0≤ x ≤9) (Monoclinic P121/n1) ,.

“…[14,77,78] The bulk phase of Sb based perovskites are explored in the specific form of Cs 3 Sb 2 Cl 9 (hexagonal P321), Cs 3 Sb 2 Br 9 (trigonal P � 3m1), MA 3 Sb 2 I 9 (hexagonal P6 3 /mmc), MA 3 Sb 2 Br 9 (trigonal P � 3m1) and (NH 4 ) 3 Sb 2 I x Br 9À x (0 � x � 9) (Monoclinic P121/n1). [28,[79][80][81] A solar cell based on (NH 4 ) 3 Sb 2 I 9 as the active light absorber shows a PCE of 0.51%. MA 3 Sb 2 I 9 and MA 3 Sb 2 Br 9 single crystals show low trap-state densities, high charge-carrier mobilities, and long charge-carrier diffusion lengths compared to other known lead-free perovskites, shows high gain and gain-bandwidth photoresponse.…”
