Customer ServiceAmorphous silicon (a-Si:H) thin-film solar cells in particular show promise for cost reduction because of their low material consumption, relatively low production heat requirements, and low temperature coefficient of solar cell performance [6].
Customer ServiceThe thin-film silicon solar cell has a long history of developing multijunction solutions to make use of these advantages. The efficiency improvement by additional subcells has been shown up to the triple-junction configuration. 10 - 17 In organic photovoltaics, the absorber materials have rather narrow absorption spectra.
To name a few notable examples, the perovskite/crystalline silicon tandem, 21 - 24 perovskite/copper indium gallium selenide (CIGS) tandem 25 and hydrogenated amorphous silicon (a-Si:H)/organic double- and triple-junction solar cells 26 have all demonstrated the potential of exceeding the efficiency of the component single-junction cells.
Double-junction solar devices featuring wide-bandgap and narrow-bandgap sub-cells are capable of boosting performance and efficiency compared to single-junction photovoltaic (PV) technologies. To achieve the best performance of a double-junction device, careful selection and optimization of each sub-cell is crucial.
For thin-film silicon solar cells, the optimum happens to be the triple-junction configuration. Beyond triple-junction, the additional losses become comparable to or even more than the gain in voltage. The loss mechanisms investigated in this work are common to all two-terminal multijunction solar cells.
Five different structures of multijunction thin-film silicon solar cells with up to four subcells were studied.
The loss mechanisms consume the potential gains in efficiency of multijunction cells. For thin-film silicon, the triple-junction is confirmed to be the best performing structure.
