Summary: This study investigates the thermoelectric properties of materials based on the chalcopyrite structure. The properties can be controlled by doping with different types and concentrations of dopants. CuInS2 exhibits n-type behavior, which can be changed to p-type by doping with Cd and Ni. CuInSe2 shows n-type behavior, but can also be changed to p-type by doping with Cd and Ni. CuInTe2 has improved thermoelectric performance with low concentrations of Cd doping.

Summary: Leaching studies of chalcopyrite can reach divergent conclusions due to the natural variability in the properties of chalcopyrite samples, such as chemical, crystallographic, and electromagnetic properties. Chalcopyrite can accommodate various galvanically active trace elements that can catalyze or inhibit leaching. While most chalcopyrites are n-type semiconductors, some are weak to moderate p-type semiconductors, which may affect leaching behavior.

Summary: Cu2SnS3 is a promising thermoelectric material for medium-temperature power generation with low-cost and environmental-benign features. Analog alloying with CuInSe2 is adopted to optimize its electrical resistivity and lattice thermal conductivity, resulting in greatly enhanced power factor and reduced lattice thermal conductivity. A peak ZT value of 1.14 at 773 K is achieved for Cu2SnS3 - 9 mol.% CuInSe2, which is one of the highest among Cu2SnS3-based thermoelectric materials. The study demonstrates that analog alloying with CuInSe2 is an effective route to unleash superior thermoelectric performance of Cu2SnS3.

Summary: This work presents an experimental study on the effects of proton irradiation on the properties of CIGS solar cells. It is found that the irradiation induces changes in the electronic structure, resulting in a decrease in photoluminescence and power conversion efficiency. A recovery strategy using multiple annealing steps is proposed, which successfully recovers the efficiency of the cells. This work highlights the potential of CIGS technology in space applications.

Summary: The antiferromagnetic semiconductor CuFeS2 is a magnetic material that is compatible with Si, making it suitable for integration with nonmagnetic semiconductors for spintronics applications. Through ab initio calculations and symmetry analysis, we find that CuFeS2 exhibits spin-polarized bands and allows for the anomalous Hall effect. We propose using cyclotron resonance to verify the effective mass tensors at specific band extrema.

Summary: This study demonstrates the successful metallization of a PERC silicon solar cell using screen-printable copper (Cu) paste. The Cu paste contains antioxidant additives and diffusion inhibitors to prevent oxidation and diffusion of Cu. The Cu-printed cells achieved an efficiency of 19% and showed no Cu diffusion after characterization tests. The long-term stability and effectiveness of the Cu diffusion barrier were also confirmed.

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.

Summary: In this study, a highly reflective ohmic contact to p-type c-Ge material is demonstrated, which can improve the efficiency of thermophotovoltaic devices. The experimental results show that this contact can simultaneously meet the requirements of good back surface passivation, low electrical resistivity, and high reflectivity. Moreover, simulations suggest that implementing these back contacts has the potential to achieve conversion efficiencies comparable to high-efficiency c-Ge TPV cells.

Summary: This study found that decorating subwavelength arrays with SiO2 quasi-nanolenses (qNL arrays) can enhance the absorption of the solar spectrum. Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
