Summary: The versatile nonfullerene perylene diimide-based electron acceptor showed good device performance in inverted organic solar cells and organic photodetectors. The ZnO films were modified with different materials to enhance electron transportation. The efficiency of the inverted device using ZnO/EG as the electron transporting layer was improved to 3.61%, with a higher Jsc of 10.06 mA/cm2. The interfacial modification also reduced the dark current of the organic photodetector and improved its external quantum efficiency.

Summary: In this study, small molecules based on PDI with amino N-oxide, dimethyldipropylenetriamino, and ethyl tosylate were used as the cathode buffer layer (CBL) in inverted type organic solar cells (OSCs). The thermal instability of PDIN-O, when used as the CBL, was addressed by introducing the side groups dimethyldipropylenetriamino and tosylate. The devices with PDIN-O, PDIN-N, and PDIN-OTs exhibited power conversion efficiencies (PCE) of 12.5%, 13.3%, and 14.2%, respectively. The ability to modulate the CBL in nonfullerene organic solar cells by introducing side groups to tune the work function at the cathode interface was demonstrated in this study. PDIN-OTs showed promise as a CBL material in inverted type devices and can be further explored by changing the counterion or side group.

Summary: Donor-acceptor Stenhouse adducts (DASAs) are a new class of negative photochromic compounds that offer high coloration and rapid photo-switching speeds. However, the relationship between binder properties and photo-switching behavior of DASAs in films is not well understood. This study investigated the rate constants of seven DASAs in five polymer binders and found a complex relationship between the glass transition temperature (Tg) of the binder, the solubility parameters of the matrix, and the push-pull nature of the donor and acceptor moieties. The rate constants of photo-switching steps that require large degrees of molecular motion were highly dependent on the Tg of the polymer binder, with higher Tg binders resulting in slower switching rates and impacting changes in color intensity. Strong relationships were also observed between the sum of the polarity and hydrogen bonding parameters and the actinic and thermal carbon-carbon double bond rotations.

Summary: The energy levels between PTB7-Th/ITIC and ZnO in a photovoltaic device are well aligned, and a double dipole is formed between PTB7-Th/ZnO. ZnO is commonly used as a cathode interface layer due to its ability to extract electrons from the active layer. This study focuses on the electronic structure of the interface between ZnO and an active layer containing PTB7-Th and ITIC. Various electron spectroscopy techniques were used to determine the energy levels of these materials at their interface. The findings show that PTB7-Th and ITIC are well aligned with ZnO, and two dipoles are formed at the PTB7-Th/ZnO interface.

The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.
