The present teachings relate to hybrid organic-inorganic perovskite solar cells including a hole-transport layer in contact with the perovskite light-absorbing layer, where the hole-transport layer (HTL) is a pristine (undoped) polymer. More specifically, the HTL comprises a copolymer including a ...
which is superior to those fabricated with doped P3HT (25%). The results of this study demonstrate that the high-mobility thiophene-based conjugated polymers can act as highly efficient and stable dopant-free HTL materials in PSCs.
000 rpm for 30 s. The doped Spiro-OMeTAD solution was prepared by dissolving Spiro-OMeTAD (32 mg), PEDOT:complex HTL Solar 3 (0.5 ml) and tris(pentafluorophenyl)borane (8 mg) in chlorobenzene (1 ml). A 5-nm-thick layer of MoO3was thermally evaporated...

The proton donor (DMPA) was covalently conjugated into the polyurethane backbone, which made the proton donor more difficult to leach out with time or electrical stimulus compared with those free dopants physically mixed in conductive polymers. Furthermore, because of the water absorption ability of...
Dopant-free methoxy substituted copper(II) phthalocyanine for highly efficient and stable perovskite solar cells Many researches manifest that the presences of dopant and additive in hole transport layer (HTL) accelerate the degradation of perovskite solar cell (PSC)... XD A,CA Cheng,TB Li,......
Ultimately, the Spiro-BD-T-doped Spiro-OMeTAD HTL showed a homogeneous and pinhole-free morphology with improved composition stability. The resultant pero-SCs exhibited an excellent PCE of 24.2% with significantly promoted long-term stability. 展开 ...
Silicon (Si) heterojunction (HJ) solar cells (SCs) with dopant‐free interdigitated back contacts (IBCs) for both polarities have attracted considerable attention because of their potential for high efficiency performance combined with a simplified process flow. However, the lack of a thorough ...
The impact of fluorine atoms on a triphenylamine-based dopant-free hole-selective layer for perovskite solar cells For industrial use, perovskite solar cells (PSCs) require long-term stability and a cost-effective hole-transport layer (HTL). The PSC stability can be sub... A Ghaderian,M Pegu...
