Tandem architecture between organic (dye-sensitized solar cell, DSSC) and inorganic (CuInGaSe2 thin film solar cell, CIGS) single-junction solar cells was constructed particularly based on a solution process. Arc-plasma deposition was employed for the Pt interfacial layer to minimize the damage to the layers of the CIGS bottom cell. Solar cell efficiency of 13% was achieved, which is significan...

Organic–inorganic metal halide perovskite solar cells represent the fastest advancing cell technology in terms of energy conversion efficiency improvement, as seen last decade. This has become a promising for next-generation, low-cost, high-efficiency photovoltaics including multi-junction tandem concepts. Double-junction have much higher limits 45%, beyond Shockley–Queisser single-junction cel...

The conversion efficiency of thin-film silicon solar cells needs to be improved to be competitive with respect to other technologies. For a more efficient use of light across the solar spectrum, multi-junction architectures are being considered. Light-management considerations are also crucial in order to maximize light absorption in the active regions with a minimum of parasitic optical losses...

In this study, the environmental impacts of monolithic silicon heterojunction organometallic perovskite tandem cells (SHJ-PSC) and single junction organometallic perovskite solar cells (PSC) are compared with the impacts of crystalline silicon based solar cells using a prospective life cycle assessment with a time horizon of 2025. This approach provides a result range depending on key parameter...

III-Sb semiconductors cover the whole 0.29–1.64 eV bandgap range, allowing us to grow several subcells of a multi-junction solar cell lattice-matched GaSb. Among alloys, AlInAsSb exhibits broadest range direct bandgaps, making it promising material for photovoltaic applications. In this work, behavior two AlInAsSb/GaSb tandem cells is studied. Material characterization and physics-based 1D mode...

The first successful deposition of 'micromorph' silicon tandem solar cells of the n-i-p-n-i-p configuration is reported. In order to implement the 'micromorph' solar cell concept, four key elements had to be prepared: First, the deposition of mid-gap, intrinsic microcrystalline silicon (μc-Si:H) by the 'gas purifier method', second, the amorphous silicon (a-Si:H) n-i-p single junction solar cel...

Mixed-halide organolead perovskites (MAPbX3) are of great interest for both single-junction and tandem solar cells because their wide band gap. In this study, we investigate the family mixed ...

Thin film silicon tandem junction solar cells based on amorphous silicon (a-Si:H) and microcrystalline silicon (lc-Si:H) were developed with focus on high open-circuit voltages for the application as photocathodes in integrated photoelectrochemical cells for water electrolysis. By adjusting various parameters in the plasma enhanced chemical vapor deposition process of the individual lc-Si:H sin...
