Summary: Bulky N-substituents of 4-(hexyloxy) phenyl-substituted and 4-(hexylthio)phenyl-substituted triphenylamine were successfully introduced into double-anchored phenothiazine dyes as capping moieties for metal-free organic sensitizers in dye-sensitized solar cells. The N-substituent of 4-(hexyloxy)phenyl-substituted TPA provided the best steric matching and resulted in a compact dye packing and an integrated shelter layer on the TiO2 surface. The DSSC performance achieved with this modification was higher than that of the reference N719-based and HL5-based DSSCs.

Summary: Solar-to-electrochemical energy storage is an important solar utilization technology, which includes solar cell and photocatalysis cell. While integrated solar batteries achieve indirect solar energy storage, the emerging coupled solar batteries allow direct solar energy storage. However, issues of rapid charge recombination and misaligned band energy have hampered the efficiency and development of coupled solar batteries. This review discusses the design of photoelectrochemical storage materials and coupled solar batteries to promote coupling between photogenerated charges and redox reactions for high efficiency, along with opportunities for new devices with matched band alignments.

Summary: Replacing pyrrole ring with pyrrolo[3,2-b]pyrrole in unidirectionally extended fused-ring electron acceptors significantly improves their performance. The designed nonfullerene acceptors 1PIC and 2PIC have red-shifted absorption peak, higher energy levels, and improved electron mobility. Photovoltaic devices based on the blend of PM6 donor and 2PIC acceptor achieve a higher power conversion efficiency due to more efficient exciton generation and dissociation, faster and more balanced carrier transport, and less charge recombination.

Summary: The control over singlet and triplet exciton populations is crucial for organic semiconductor technologies. This study investigates the rate of intersystem crossing (ISC) and demonstrates the occurrence of intramolecular triplet formation in both solution and solid state. It is found that structural distortions in disordered films lead to increased spin-orbit coupling, enabling rapid ISC. The proposal also reveals the role of rotational flexibility and conformational disorder in accelerating ISC. Overall, this work sheds light on the factors affecting ISC and provides a framework for molecular control over spin states.

Summary: This study investigated the performance evaluation parameters of semitransparent organic solar cells (ST-OSCs), namely, the average visible transmittance (AVT) and power conversion efficiency (PCE). By reducing the donor content, light absorption in the visible region can be decreased and the AVT values of ST-OSCs can be increased. However, a lower donor content affects exciton generation, exciton dissociation, and charge transport, thereby limiting the PCEs of the cells.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. 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. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

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.
