4-Tert-butylpyridine-assisted low-cost and soluble copper phthalocyanine as dopant-free hole transport layer for efficient Pb- and Sn-based perovskite solar cells

Phthalocyanines, porphyrins and other porphyrinoids as components of perovskite solar cells

“…Compared with doped spiro-OMeTAD, CuPc-OBu -based devices were efficient enough (PCE= 19.01% vs. 19.96% for spiro-OMeTAD-based devices) and more stable than the spiro-OMeTAD-based devices when subjected to 85 °C with 45% RH for 1000 h. Besides, in Sn-based 3D PSCs, and comparing it this time with the polymer PTAA, CuPc-OBu -based devices were more efficient and more stable than its polymeric counterpart. 54 In a work published by Yu et al in 2021, a really interesting comparison can be found between Pcs with different central metals but with the same peripheral methoxyethoxy substituents ( CoPc , NiPc , CuPc , ZnPc and H 2 Pc ; Fig. 9f and Table 3).…”

PCE of 21.23% (certified 21.03%), in contrast to the maximum PCE of 5.41% that was obtained with CoPc-based devices.…”

Phthalocyanine in perovskite solar cells: a review

“…The photovoltaic properties of some selected perovskite devices using Pc compounds as additives in the perovskite layer are summarized in Table 4. 139–147…”

“…The photovoltaic properties of some selected perovskite devices using Pc compounds as additives in the perovskite layer are summarized in Table 4. [139][140][141][142][143][144][145][146][147] Tang and coworkers explored the impact of post-treating the MAPbI 3 perovskite layer using tetra-ammonium-substituted ZnPc on the device performance. 144 The two-dimensional (ZnPc) 0.5 MA nÀ1 Pb n I 3n+1 was constructed in the grain boundaries of the MAPbI 3 film by immersing the as-fabricated perovskite layer in an isopropanol solution of the ZnPc derivative (71), resulting in the successful passivation of defects and reduced trap-assisted recombination.…”

Stable perovskite solar cells with efficiency of 22.6% via quinoxaline-based polymeric hole transport material

“…Conjugated polymers, with their excellent intrinsic stability and easily tunable photoelectric properties, have been used as efficient and stable HTMs for pero-SCs [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49]. In the conjugated polymers, planar structured D-A copolymers composed of an electron-donating (D) unit and an electronaccepting (A) unit possess the advantages of high hole mobility and tunable electronic energy levels by selecting different D-unit and different A-unit with different side chains.…”
