Within the silicon photovoltaics (PV) community, there are many approaches, tools, and input parameters for simulating solar cells, making it difficult for newcomers to establish a complete and representative starting point and imposing high requirements on experts to tediously state all assumptions and inputs for replication. In this review, we address these problems by providing complete and representative input parameter sets to simulate six major types of crystalline silicon solar cells. Where possible, the inputs are justified and up-to-date for the respective cell types, and they produce representative measurable cell characteristics. Details of the modeling approaches that can replicate the simulations are presented as well. The input parameters listed here provide a sensible and consistent reference point for researchers on which to base their refinements and extensions.
Tandem solar cells
(SCs) based on perovskite and silicon represent
an exciting possibility for a breakthrough in photovoltaics, enhancing
SC power conversion efficiency (PCE) beyond the single-junction limit
while keeping the production cost low. A critical aspect to push the
tandem PCE close to its theoretical limit is the development of high-performing
semitransparent perovskite top cells, which also allow suitable near-infrared
transmission. Here, we have developed highly efficient semitransparent
perovskite SCs (PSCs) based on both mesoporous and planar architectures,
employing Cs0.05(MA0.17FA0.83)0.95Pb(I0.83Br0.17)3 and FA0.87Cs0.13PbI2Br perovskites with band
gaps of 1.58 and 1.72 eV, respectively, which achieved PCEs well above
17 and 14% by detailed control of the deposition methods, thickness,
and optical transparency of the interlayers and the semitransparent
electrode. By combining our champion 1.58 eV PSCs (PCE of 17.7%) with
an industrial-relevant low-cost n-type Si SCs, a four-terminal (4T)
tandem efficiency of 25.5% has been achieved. Moreover, for the first
time, 4T tandem SCs’ performances have been measured in the
low light intensity regime, achieving a PCE of 26.6%, corresponding
to revealing a relative improvement above 9% compared to the standard
1 sun illumination condition. These results are very promising for
their implementation under field-operating conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
