Chinese Chemical Letters 2022年第4期33卷 1772-1778页

Organic metal halide perovskite materials have excellent photoelectric properties, and the power conversion efficiency(pCE) of the perovskite solar cells(pSCs) has increased from 3.8% to more than 25%. In the development of pSCs, innovative architectures were being proposed constantly. However, the use of the electron transport layer(ETL) and hole transport layer(HTL) increases manufacturing costs and process complexity. perovskite material has ambipolar charge transport characteristics, so it could functionalize as both the optical absorption layer and carrier transport layer(CTL). In this review, we analyzed the p/n-type perovskite materials, perovskite p-n homojunction solar cells, and carrier transport layers-free(CTLs-free) devices. Finally, we propose some innovative device architectures. We hope that this mini review could pave way for the simplification of the architectures, promote the preparation of the low-cost and high-efficiency devices, and accelerate the commercialization of the pSCs.

第六届新型太阳能电池材料科学与技术学术研讨会

Surface modification is a practical approach to reduce carrier recombination at the surface and subsurface of the perovskite films caused by the trap states and the intrinsic nature of polycrystalline organometallic perovskites. Organic-inorganic hybrid perovskite solar cells(pSCs) contain several interfaces in the device structure. Herein, an F4TCnQ interfacial layer is introduced at the interface of HTM layer and perovskite absorber layer, which possess dual function, i.e., surface passivation and interfacial doping of the perovskite. pSCs with the dual function interfacial layer exhibit remarkable improvement in device performance and show enhanced long-term stability in ambient air without device encapsulation. The structure of the perovskite solar cells is another critical factor influencing the device performance of perovskite solar cells. We present a novel perovskite p-n homojunction structure for highly-efficient and stable pSCs. The presence of perovskite homojunction in perovskite devices could promote the separation of carriers by the build-in electronic field of the p-n homojunction, and improve the electron extraction in pSCs. The efficiency increasing from 17.7% for planar structure to 20.8% for the MApbI-based pSCs with the p-n homojunction. Meanwhile, by employing the cation-immobilized perovskite materials to fabricate pSCs, the champion efficiency of 20.86 % with negligible hysteresis is acquired.
