Despite the high efficiencies reached by heavily doped poly-Si/SiOx passivating contact solar cells, challenges like the high front parasitic absorption still limit their performance. Previously, we showed a wet etching technique using self-aligned metal grids to remove the front poly-Si in the non-metallized region. Here, we focus on the effective dielectric passivation on this tunneling oxide/n+ in-diffused region. The effect of poly-Si thickness was studied to balance between the passivation quality and the current gain. We then compared various dielectric passivation schemes using SiNx, Al2O3, and stacks thereof via injection-level dependent lifetime and the transfer length method. We demonstrate a SiNx/Al2O3 stack yielded the best passivation performance within device process limitation and obtained an improved front/back poly-Si/SiOx passivating contact device, with a short circuit current density of 41.8 mA/cm2 and an efficiency of 21.8%.

This work presents a method for decomposing realtime on-site measured plane of array (POA) and global horizontal (GHI) irradiance from pyranometers into beam and diffuse components. A machine learning method is applied in conjunction with typical metereological year (TMY) irradiance data to facilitate reliable irradiance decomposition of five minute measured data, a regime in which conventional decomposition methods like GTI-DIRINT sometimes struggle. The approach is combined with view factor models of rear side irradiance for bifacial systems to reliably calculate performance ratio and other metrics. Validation of the method on bifacial utility-scale solar power plant data shows credible results.

Controlled spalling is an emerging technique developed for fast, scalable wafer reuse, but for the commonly used (100) GaAs substrate system, the process leaves large facets ranging from 5-10 µm on the wafer surface. Removing them for wafer reuse requires a costly re-polishing step that limits the cost savings that can be achieved with spalling as a wafer reuse technique. In this study, we investigate facet suppression in spalling of (100) GaAs by redirecting the fracture front along features created by buried nanoimprint lithography (NIL)-patterned SiO2. We show successful facet suppression using patterns that result in favorable fracture along the SiO2/GaAs interface. The results from this work show NIL patterned interlayers are a promising method for faceting suppression in (100) GaAs spalling.

Solar cells in PV modules crack during field operation from environmental stressors, including extreme weather events, such as hailstorms and hurricanes. These cracks can lead to gradual or immediate acute power degradation. To directly address cell-crack-induced degradation, we have formulated a carbon nanotube additive for commercial screen printed silver pastes. We have shown in previous work that these metal matrix composites have little to no effect on the cell’s efficiency while enhancing the metallization’s fracture toughness and electrical gap-bridging capability. In this work, we focus on optimizing the composite metallization to achieve the best possible performance. We discover that reducing carbon nanotube agglomerations in the paste not only improves the printability for narrow gridlines, but also increases the modulus of toughness of the metallization by over 500%.

The long-term reliability of photovoltaic (PV) modules is essential to decrease the levelized cost of electricity and is dependent on module packaging choices. In this paper, we study the degradation of double glass (DG) and glass-backsheet (GB) PV modules with ethylene-vinyl acetate (EVA) and polyolefin elastomer (POE) encapsulants using multicrystalline PERC cells under accelerated exposures including modified damp heat (mDH) and mDH with full-spectrum light (FSL). The results showed that the modules with opaque rear encapsulant have greater power loss on average than those with UV-cutoff rear encapsulant for each module type. The dominant degradation mechanism was series resistance (Rs) increase indicating interconnect corrosion for most module types. In addition to the increased Rs, GB modules with UV-cutoff rear encapsulant experienced power loss by transmission loss, and the POE_GB type under mDH+FSL also had more cell shunting. For modules with opaque rear encapsulant, the POE_DG type under mDH+FSL had power loss dominated by transmission loss.

Organic solar cells in ternary architecture have gained recent importance owing to their superior photovoltaic performances. In this work, we report fabrication and characterization of thermally evaporated small molecule based ternary bulk hetero junction (BHJ) organic photovoltaic (OPV) cells. To this we have used DTDCTB as a donor material, ICBA and C70 are used as electron acceptors in the active layer. The fabricated ternary OPV devices were tested under AM 1.5 solar irradiation. The fabricated devices were optimized for better performance at different annealing temperatures. Ternary device DTDCTB:C70: ICBA (1:0.2:1) presented the best efficiency of 4.68% when annealed at 90°C for 30 minutes. The obtained ternary OPV results were compared with the binary host system and reported efficient ternary OPVs and they are batch to batch reproducible.

Still in many countries due to lack of electricity and not available of electrical infrastructure people is still using Diesel Genset (DG) for Agriculture activity. This DG set uses a diesel which is producing green house gases. Solar PV Smart Microgrid(SSM) system is best option of this DG set and it solve the energy and environment issue for this isolated community. This paper aims at analysing the techno-economic-environment sustainability of Solar PV Smart Microgrid(SSM) for sustainable rural electrification in Agriculture community. Modelling is used to perform optimization and sensitivity analysis. The analysis showed that SSM consist of solar photovoltaics (PV) is the least cost optimal system. This system ensures a reliable power supply without Conventional power and achieves 100% CO2 emissions reduction compared to a conventional power. Moreover, the study demonstrated that the most economical SSM depends strongly on the potential energy sources available at a location and power plant's remoteness from the beneficiary. The existing power supply configuration has also been compared to the best system after analyzing and investigating all technical and economic feasibility. The results show that the current diesel-based system is not viable for the village’s people, but rather a heavy burden to them due to the high cost of per unit electricity. In contrast, a Solar PV Smart Microgrid appeared to be the most feasible system. The proposed system is found to be around 33% inexpensive considering the net present cost and cost of energy, respectively, with a 100% share of renewable energy which reduces 63,750 kg carbon dioxide per year.

In this paper we are reporting a new approach by using thermoplastically and electrically conductive coated wires (so-called TECC wires) to interconnect solar cells – it is a modified multi-wire technology. The typical process temperature range is 130°C – 180°C which makes it suitable for temperature sensitive solar cells such as silicon heterojunction (SHJ) or silicon-perovskite tandem solar cells. The wires consist out of a round copper core with a diameter of 280 µm which is covered by a very thin layer of silver for corrosion protection, and then surrounded by about 40 µm coating of an electrically conductive thermoplastic material. As many as required wires can be applied on the busbarless solar cells.

Tandem technology has gained track during the last decade to surpass the theoretical efficiency of a single layer solar cell of 31%. However, there are some challenges that must be addressed before tandems can reach the commercialization level. A stable power conversion efficiency for a high bandgap solar cell compatible with a tandem structure is one of the main issues that prevents perovskites in reaching the market. Here, it is proposed the necessary steps to make stable tandem solar cells by having a 100% controlled process of a high bandgap perovskite solar cell, a hypothetical low bandgap perovskite solar cell, and their respective union into a tandem.
