Flexible micromorph tandem a-Si/ c-Si solar cells
The deposition of a stack of amorphous a-Si:H and microcrystalline c-Si:H tandem thin film silicon solar cells micromorph requires at least twice the time used for a single junction a-Si:H cell. However, micromorph devices have a higher potential efficiency, thanks to the broader absorption spectrum of c-Si:H material. High efficiencies can only be achieved by mitigating the nanocracks in the c...
متن کاملRecent Progress of the "micromorph" Tandem Solar Cells
The paper gives an overview over recent results and future potentials of the cornbined ainorphous silicon/microcrys~alline silicon "micromorph" tandem cell technology. The reported results include replacement of boron-microdoping compensation by employment of gas-purification to obtain mid-gap iriicrocrystailine silicon, leading to tne fabrication of a 3.6 ~m thick microcrystalline silicon p-i-...
متن کاملMICROMORPH (MICROCRYSTALLINE / AMORPHOUS SILICON) TANDEM SOLAR CELLS: Status Report and Future Perspectives
Hydrogenated microcrystalline silicon (μc-Si:H) as deposited by PECVD at low temperatures (around 200°C) can be used to fabricate stable pin-type solar cells with conversion efficiencies over 8 %. The variety of growth forms and microstructural patterns observed for different deposition conditions is described; the requirements to be met by layers for use in μc-Si:H solar cells are listed. A pa...
متن کاملNanopyramid structure for ultrathin c-Si tandem solar cells.
Recently, ultrathin crystalline silicon solar cells have gained tremendous interest because they are deemed to dramatically reduce material usage. However, the resulting conversion efficiency is still limited by the incomplete light absorption in such ultrathin devices. In this letter, we propose ultrathin a-Si/c-Si tandem solar cells with an efficient light trapping design, where a nanopyramid...
متن کاملSimulation study of GaAsP/Si tandem solar cells
A model, adapted from the Shockley-Queisser detailed balance model to tandem solar cells with a monolithically grown GaAsxP1-x top junction on a Si bottom junction, has been developed. Updated data have been used for the absorption spectrums. Two surface geometries, flat and ideally textured, have been investigated. As an important improvement over existing models, the effects of threading-disl...
