Summary: Controlling the morphology of BHJ films in solution processed polymer solar cells (PSCs) is crucial for enhancing their performance. In this study, bis(5-chlorothiophen-2-yl)alkanes (BCTA-m) with varying lengths of alkane chains (m = 3, 4, 5, and 6) were used as solvent additives to fabricate inverted PM6:Y6 PSCs. It was observed that the BCTA-4 additive resulted in the highest power conversion efficiency (PCE) of 15.59% compared to other BCTA-m additives and similar to the reference additive 1-chloronaphthlene (CN, PCE = 15.62%). The BCTA-4 device showed improved exciton generation and dissociation, charge transport, and suppressed charge recombination. This work demonstrates the potential of BCTA-4 additive for high-performance inverted PSCs based on Y6-type acceptors.

Summary: In this study, a novel multinitrogen derivative interlayer, Anth-hpp2, was designed and synthesized between the PCBM and top Ag electrode in inverted perovskite solar cells. The superbase group in Anth-hpp2 effectively contacts the silver electrode, reducing the work function of Ag. As a result, the power conversion efficiency of the Anth-hpp2-based device improved from 16.05% to 20.37%, along with enhancements in short-circuit current and fill factor. The stabilities of perovskite solar cells with Anth-hpp2 were also greatly improved.

Summary: By introducing the humidity-assisted polymerizable additive MMDS, efficient CsPbI3 perovskite solar cells (PSCs) can be fabricated in common air without humidity control. MMDS molecules can react with water in the air and self-polymerize to form a water-resistant polymer at grain boundaries, preventing further moisture invasion. The -SH group in MMDS can passivate under-coordinated Pb2+ and reduce trap density in CsPbI3 films. As a result, high efficiencies of >18% are achieved in inverted CsPbI3 PSCs regardless of the relative humidity between 40% and 80%.

Summary: Compared to linear NFAs, multi-dimensional NFAs with extended conjugated structures in multiple directions show potential for improving absorption, molecular packing, and charge transport dynamics in organic solar cells. In this study, a conjugated-skeleton connection mode is developed, extending linear molecular structures towards three-dimensions. The resulting 3D NFAs exhibit low reorganization energy, fibrillar network film morphology, enhanced charge transport behavior, and improved stability. By optimizing the molecular geometry using fluorine-induced noncovalent conformational locks, a remarkable efficiency of 17.05% is achieved in binary bulk-heterojunction OSCs based on CH8-1, which represents the highest value for multi-dimensional acceptors to date. This work paves the way for further molecular structural optimization of state-of-the-art NFAs.

Summary: This study compared the conventional and inverted BHJ solar cells composed of a non-polymeric donor and [6,6]-phenyl-C71 butyric acid methyl ester (PC71BM) as the acceptor. It was found that the conventional device structure had higher power conversion efficiencies due to a smaller component of bimolecular recombination. The larger bimolecular recombination losses in the inverted device were caused by the phase separation of PC71BM, resulting in reduced hole extraction efficiency.

Summary: Efficient surface passivation of perovskite solar cells is achieved by introducing synthesized amine-functionalized fullerenes with increasing carbon chain lengths as interface passivation layers. The longer chain length amine-functionalized fullerene exhibits a more beneficial effect on device performance, resulting in a high power conversion efficiency of 21.2%. The surface energy, perovskite crystallite size, and electron transfer capacity are correlated with the linker chain length. This study unravels the mechanism of the passivation effect through amine-induced anchored crystallization of perovskite.

In this study, a phosphine-based solid additive was used to modify the phase-separated morphology of a photoactive layer, resulting in improved device performance. The fluorine bonding interaction and volatilization of the additive induced the rearrangement of the bulk heterojunction nanostructure, leading to larger crystalline sizes and enhanced charge separation and transport properties. With an optimal concentration of the solid additive, the power conversion efficiency of the devices significantly increased from 15.1% to 16.9%.

The results show that higher absorptivity increases heating rate and steady state temperature of the elytra. There is significant variation in absorptivity, which is achieved through different combinations of reflectivity and transmissivity. Size plays a role in predicting temperature change, while the presence of elytra reduces heating of the body.

The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements.
