AbstractThe photovoltaic performance of perovskite solar cells (PSCs) can be improved by utilizing efficient front contact. However, it has always been a significant challenge for fabricating high-quality, scalable, controllable, and cost-effective front contact. This study proposes a realistic multi-layer front contact design to realize efficient single-junction PSCs and perovskite/perovskite tandem solar cells (TSCs). As a critical part of the front contact, we prepared a highly compact titanium oxide (TiO2) film by industrially viable Spray Pyrolysis Deposition (SPD), which acts as a potential electron transport layer (ETL) for the fabrication of PSCs. Optimization and reproducibility of the TiO2 ETL were discreetly investigated while fabricating a set of planar PSCs. As the front contact has a significant influence on the optoelectronic properties of PSCs, hence, we investigated the optics and electrical effects of PSCs by three-dimensional (3D) finite-difference time-domain (FDTD) and finite element method (FEM) rigorous simulations. The investigation allows us to compare experimental results with the outcome from simulations. Furthermore, an optimized single-junction PSC is designed to enhance the energy conversion efficiency (ECE) by > 30% compared to the planar reference PSC. Finally, the study has been progressed to the realization of all-perovskite TSC that can reach the ECE, exceeding 30%. Detailed guidance for the completion of high-performance PSCs is provided.

<p>The performance of methylammonium lead triiodide (CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>) based solar cells depends on its crystallization and controlled microstructure. In spite of its high performance, long-term stability is a paramount factor towards its large area fabrication and potential industrialization. Herein, we have employed poly(vinylidene fluoride−trifluoro ethylene) P(VDF-TrFE) as an additive into a low concentration based perovskite precursor solutions to control the crystallinity and microstructure. Perovskite layers of lower thickness can be derived from low precursor concentration, however it often suffers from severe voids and roughness. Introducing judicious quantities of P(VDF-TrFE) can improve the surface coverage, smoothness as well as reduces the grain boundaries in the perovskite. An array of characterization techniques were utilized to probe the structural, microstructural and spectroscopic properties. Impedance spectra suggests, the P(VDF-TrFE) can improve the carrier lifetimes and reduce the charge transfer resistance, which in turn allows to improve photovoltaic performance. For an optimized concentration of P(VDF-TrFE), the fabricated semi-transparent solar cells yielded power conversion efficiency in excess of 10%, which supersede pristine devices along with improved stability. The device architect and the fabrication technique provide an effective route to fabricate cost effective and visible-light-semi-transparent perovskite solar cells.</p>

<p>Developing cost-effective and rational hole transporting materials is critical for fabricating high-performance perovskite solar cells (PSCs) and to promote their commercial endeavor. We have designed and developed pyridine (core) bridging diphenylamine-substituted carbazole (arm) small molecules, named as <b>2,6PyDANCBZ </b>and <b>3,5PyDANCBZ</b>. The linking topology of core and arm on their photophysical, thermal, semiconducting and photovoltaic properties were probed systematically. We found that the <b>2,6PyDANCBZ </b>shows higher mobility and conductivity along with uniform film-forming ability as compared to <b>3,5PyDANCBZ</b>. The PSCs fabricated with <b>2,6PyDANCBZ </b>supersede the performance delivered by Spiro-OMeTAD, and importantly also gave improved long-term stability. Our findings put forward small molecules based on core-arm linking topology for cost-effective hole selective layers designing.</p>
