Summary: This paper presents the performance evaluation of a modified indirect solar dual collector dryer (MIS2CD) integrated with a thermal storage system for drying myrobalan slices. The findings show that the thermal efficiency and energy supply period of MIS2CD increased by 12+/-2% and 41+/-1.2%, respectively. The drying characteristics of myrobalan slices in MIS2CD were compared to TD and OSD methods, and a two-term exponential model best explains the drying kinetics in MIS2CD. The CO2 emissions and CO2 reduction for drying myrobalan in MIS2CD were calculated for a lifetime of 20 years, resulting in 67.85 kg and 20.65 tons, respectively. The economic evaluation showed a total benefit of 22,622 INR (annually) and a benefit-cost ratio of 2.08 for myrobalan dried in MIS2CD compared to TD. The payback period of MIS2CD was evaluated as 2.18 years, much less than the dryer's lifetime.

Summary: Experimental investigation on two solar air collectors (SACs) with modified absorber plates shows that the cross-corrugated trapezoidal SAC produces up to 7.72% more energy than the reverse trapezoidal SAC. Energy efficiency increases with tilt angle and a threefold increase in air mass flow rate leads to 100-105% increase in energy and exergy efficiencies. Overall, the environmental impact factor of the type-II SAC is significantly lower than that of the type-I SAC.

Summary: This study investigates the effect of an innovative turbulator with different geometric shapes and two-phase Cu-GO/water hybrid nanofluid on the thermal-hydraulic performance, exergy efficiency, and energy efficiency of a flat plate solar collector (FPSC). The use of the turbulator improves the thermal-hydraulic performance of the FPSC, and increasing the curvature angle significantly affects the heat transfer rate and pressure drop enhancement. Energy and exergy efficiencies are influenced by various factors such as inlet velocity, turbulator geometric shape, and FPSC boundary conditions.

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.
