Summary: In the past years, high-performance organic solar cells have emerged, reducing the amount of energetic disorder in structurally disordered semiconductors. It is crucial to accurately characterize this disorder when searching for future high-efficiency material systems. Common techniques include optical excitation and external voltage measurements, with the former yielding lower values of energetic disorder compared to the latter. Electrical measurements probe different energy ranges than optical measurements due to subband-gap density of states. Limitations and discrepancies between measurement techniques are explained based on electronic parameters.

Summary: Organic semiconductor nanoparticle dispersions are effectively stabilized with small amounts of the p-doping agent 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F(4)TCNQ), eliminating the need for surfactants. This concept can be applied to synthesize dispersions from various light-harvesting benzodithiophene-based copolymers. The resulting dispersions are used to fabricate organic solar cells (OSCs) without any detrimental effect on device performance. This approach enables the eco-friendly fabrication of high-efficiency light-harvesting semiconductor-based OSCs by eliminating environmentally hazardous solvents.

Summary: Solar-blind photodetectors based on p-organic/n-Ga2O3 hybrid heterojunctions have been investigated. A multifunctional photodetector based on p-PCDTBT/n-Ga2O3 is fabricated and shown to work in both phototransistor mode and self-powered mode. The introduction of PCDTBT reduces the dark current and enhances the photoresponse parameters of the photodetector to solar-blind UV light. Moreover, the built-in field in the heterojunction enables self-powered behavior.

Summary: Insight into the identity and origin of defects in organic semiconductors is crucial for targeted strategies to overcome them. The study focuses on PM6:Y6 organic solar cells and reveals that defects are formed by a trace constituent in ambient air and O-3. Aging in H2O-saturated compressed air also increases the defect response by modifying the work function of MoO3. Measurement of energy resolved-electrochemical impedance spectroscopy and different cell structures confirm that defects mainly originate from PM6 and are located near the top electrode.

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: 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.
