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 effects of various wafer properties and geometric features on the performance of heterojunction back-contact (HBC) crystalline silicon (c-Si) solar cell based on n-type c-Si wafer were systematically studied using Quokka simulation. Preferred values of parameters for high efficiency of the HBC solar cell were proposed, including emitter percentage, total pitch of P and N regions, wafer thickness, wafer resistivity, wafer bulk lifetime, and contact ratio of the TCO film. Higher cell efficiency can be obtained with an emitter percentage of 80%, a total pitch of P and N regions of 1.6 mm, a wafer thickness in the range of 90-120 μm, a wafer resistivity of 0.5 Ω·cm-0.9 Ω·cm, a wafer bulk lifetime not less than 4 ms, and a larger contact ratio of the TCO.

Summary: Monolithically stacked tandem solar cells offer the opportunity to absorb more solar radiation with reduced energy loss, with carefully adjusted bandgaps to avoid competition for photons. Two-terminal tandem solar cells using wide bandgap amorphous silicon and narrow bandgap NFA bulk-heterojunction show high power conversion efficiencies exceeding 15%, with interface engineering allowing for stability across a wide range of light intensities. The addition of an inorganic silicon subcell enhances operational stability and reduces light-stress on the bulk heterojunction, addressing a longstanding challenge in organic photovoltaic research.

Summary: The solar-driven calcium looping process (CaL) has great potential for thermochemical energy storage, but the calcium-based particles used as energy carriers are prone to fragmentation, which significantly reduces the efficiency and stability of energy storage. In this study, a particle scale model is proposed to investigate the characteristics of energy storage performance. The model confirms that stress failure at the particle center is the main cause of energy carrier fragmentation due to high radial tensile stress. The study also explores the operation conditions and modified particle properties to improve energy storage performance.
