In this study, a mechanical stacking technique has been used to bond together the GaInP/GaAs and poly-silicon (Si) solar wafers. A GaInP/GaAs/poly-Si triple-junction cell mechanically stacked using low-temperature bonding process which involves micro metal balls on line high-optical-transmission spin-coated glue material. Current–voltage measurements of cells have carried out at room temperatur...

We demonstrate a monolithic perovskite/CIGS tandem solar cell with certified power conversion efficiency (PCE) of 24.2%. The still exhibits photocurrent mismatch between the subcells; thus optical simulations are used to determine optimal device stack. Results reveal high potential optimized reaching short-circuit current density 19.9 mA cm–2 and 32% PCE based on semiempirical material properti...

Flexible perovskite-based tandem solar cells could be the game-changer for next-generation flexible photovoltaics.

The defect-free IDDQ has two major components: (i) the reverse biased p-n junction leakage current, and (ii) the transistor sub-threshold leakage (off) current. The reverse biased p-n junction leakage current can be further divided into two segments: state dependent, and state independent. The state dependent component p-n junction leakage current depends on the reverse biasing of the p-n junct...

Monolithic hybrid halide perovskite/crystalline silicon (c-Si) tandem solar cells have demonstrated their great potential to surpass the theoretical efficiency limit of single-junction devices. However, stability perovskite sub-cells is inferior that c-Si been commercialized, casting serious doubt about lifetime entire device. During device operation, light and heat are inevitable, which requir...

UNLABELLED A highly stable monolithic tandem solar cell was developed by combining the heterogeneous photovoltaic technologies of dye-sensitized solar cell (DSSC) and solution-processed CuInxGa1-xSeyS1-y (CIGS) thin film solar cells. The durability of the tandem cell was dramatically enhanced by replacing the redox couple from to [Co(bpy)3](2+) /[Co(bpy)3](3+)), accompanied by a well-matched co...

Tandem "Z-scheme" approaches to solar-to-chemical production afford the ability to independently develop and optimize reductive photocatalysts for CO2 reduction to multicarbon compounds and oxidative photocatalysts for O2 evolution. To connect the two redox processes, molecular redox shuttles, reminiscent of biological electron transfer, offer an additional level of facile chemical tunability t...
