Compared to conventional (p-i-n) organic photovoltaics (OPVs), inverted (n-i-p) OPVs hold promise for future commercial applications due to their advantages in printing process compatibility and environment robustness. The current bottleneck lies in the efficiency and light stability, which is closely related to the defects and the photocatalytic reactivity of metal oxides transport layer. This comment summarizes the recent progress on inverted OPV and outlines potential solutions to surmount the hurdles before the technology can be put into production.

Nonfullerene acceptor-based organic solar cells have recently taken a milestone leap with power conversion efficiencies approaching 20%. A key to further boost the efficiencies up to the Shockley-Queisser limit rests upon attaining a delicate balance between exciton dissociation and charge transport. This perspective presents two seminal and reciprocal strategies developed by our group and others to reconcile the intricacy of charge carrier dynamics, spanning from intrinsic molecular structure design to extrinsic dopant exploitation.

Perovskite materials have revolutionized optoelectronics by virtue of their tunable bandgaps, exceptional optoelectronic properties, and structural flexibility. Notably, the state-of-the-art performance of perovskite solar cells has reached 27%, making perovskite materials a promising candidate for next-generation photovoltaic technology. Although numerous reviews regarding perovskite materials have been published, the existing reviews generally focus on individual material systems (e.

The photovoltaic performance of CuZnSn(S,Se) is limited by open-circuit voltage losses (ΔV) in the radiative (ΔV) and non-radiative (ΔV) limits, due to sub-bandgap absorption and deep defects, respectively. Recently, several devices with power conversion efficiencies approaching 15% have been reported, prompting renewed interest in the possibility that the key performance-limiting factors have been addressed. In this work, we analyze the sources of ΔV in these devices and offer directions for future research.

The number of polymeric and small-molecular acceptors for organic photovoltaics has exploded in the past decade. As a result, physical insights and efforts aiming at elucidating the coupling between composition and behaviour are required more than ever. Here we present an encompassing study into the phase behaviour of 55 polymer:small-molecular acceptor blends, pivotal in determining device performance and stability.

Bifunctional integration of indoor organic photovoltaics (OPVs) and photodetectors (OPDs) faces fundamental challenges because of incompatible interfacial thermodynamics: indoor OPVs require unimpeded charge extraction under low-light conditions (200-1000 lx), whereas OPDs require stringent suppression of noise current. Conventional hole transport layers (HTLs) fail to satisfy these opposing charge-dynamic requirements concurrently with commercial practicality (large-area uniformity, photostability, and cost-effective manufacturability). This study introduces benzene-phosphonic acid (BPA)-a minimalist self-assembled monolayer (SAM)-based HTL with a benzene core and phosphonic acid anchoring group-enabling cost-effective synthesis and excellent ITO interfacial properties such as energy alignment, uniform monolayer, and stability.
