Summary: Imide-functionalized arenes have shown great potential as acceptor units in organic solar cells (OSCs). However, the use of dithienophthalimide (DPI) has been limited due to the high cost of synthesis. In this study, the synthesis of DPI skeleton was simplified and the cost was significantly reduced using chromium-mediated cyclization. Two nonhalogenated D-A copolymers based on DPI were successfully synthesized. The binary OSCs based on pBDTT-DPI-Me : Y6 achieved a high power conversion efficiency of 16.55%, demonstrating DPI as an attractive A-unit for further exploration in OSCs.

Summary: Utilizing a trap-assisted compensation model, the study explains how polycrystalline Si passivating contacts achieve low leakage current in IBC monocrystalline Si solar cells through dopant compensation between the doped fingers. Analysis of dopant distribution in the isolation region reveals a well-compensated area between the doped fingers, preventing shunting losses. The compensation mechanism widens the compensated region significantly, resulting in a high-resistivity area and low shunt current, as demonstrated by simulations and measurements.

Summary: The quality of the electron transporting layer (ETL) is crucial for the performance and stability of perovskite solar cells (PSC). Defects in the ETL can lead to charge recombination losses and device instability. This study proposes the use of bilayered crystalline chromium-doped zinc stannate (Cr-doped Zn2SnO4) nanoparticles with a compact zinc tin oxide (c-ZTO) as an efficient ETL in PSC. It was found that the incorporation of Cr improved the quality of the ZTO crystal, resulting in a perovskite film with larger grains and enhanced device stability.

Summary: Si-based photovoltaic solar power is rapidly developing as a renewable and green energy source. Traditional chemical methods for preparing solar-grade Si and recycling Si waste have limitations, while metallurgical methods show promise but have challenges. Solvent refining is the most promising and environmentally friendly approach for obtaining low-cost solar-grade Si. A simple and green approach combining solvent refining, slag treatment, or vacuum directional solidification is proposed for low-cost Si preparation.

Summary: Safe implementation of reusable crucibles in the silicon PV industry requires a thorough understanding of reactions to avoid liquid infiltration and crucible failure. By adding colloidal silica to silicon nitride coating, the oxygen concentration can be controlled, crucible degradation can be avoided, and the pre-oxidation step can be eliminated. An analytical model was used to quantify the effect of oxygen content in the coating on the depletion rate, providing insight into hindering liquid infiltration by forming and stabilizing silicon oxynitride in the coating.

Summary: This study demonstrated the combined use of white light interferometry (WLI) and Laue X-ray crystallography scanner characterisation to investigate the chemical etching response of diamond cut multi-crystalline Si (mc-Si) wafers. The topography of mc-Si surfaces before and after etching was examined to evaluate the effect of different texturing additives. The results illustrated the influence of different crystal orientations on the etching rate, with the etching speed increasing with the crystallographic similarity to the main (hkl) planes (100,110,111). The comparison of isopropyl alcohol (IPA) and sodium hypochlorite (NaOCl) additives showed NaOCl to be favorable for polishing mc-Si wafers, while IPA can only be used for crystal grains close to the (111) orientation.

Summary: The effects of boron at various concentrations on low copper spheroidal graphite iron (SGI) were investigated. It was found that boron had no noticeable effect on the size distributions, number densities, or morphologies of microparticle populations, as well as the size distributions or number densities of graphite nodules at concentrations of 130 to 140 ppm. However, even at concentrations as low as 24 ppm, boron was observed to cause rough surface morphology of graphite nodules.

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.
