Lightweight flexible perovskite solar cells are promising for building integrated photovoltaics, wearable electronics, portable energy systems and aerospace applications. However, their highest certified efficiency of 19.9% lags behind their rigid counte
Tandem solar cells use two absorbers instead of one, each specializing in a region of the solar spectrum, raising the theoretical efficiency to 46%2. This helps reduce the energy lost to electron-phonon scattering events (thermalization), the most prominent intrinsic loss mechanism in solar cells...
All-perovskite four-terminal (4T) tandem solar cells have gained great attention because of solution-processability and potentially high efficiency without a need for current-matching between subcells. To make the best use of a tandem architecture, the subcell bandgaps and thicknesses must be ...

"The HTLs based on SAMs are emerging as a hot topic in perovskite community recently, and our approach opens a new way of using SAM molecules for more efficient perovskite solar cells," Tan added. "We will now further reduce the interfacial losses of other interfaces in flexible all-perovski...
Among them, all-perovskite tandem solar cells exhibit unique advantages of both low-cost fabrication and high efficiency. They have advanced rapidly in these years, due to the realization of stable and efficient narrow-bandgap perovskites. In this work, we review the development of monolithic all-...
This approach results in all-perovskite tandem solar cells with improved fill factor, voltage, and stable efficiencies of up to 23.1%. Using the flex-compatible nature of the recombination layer developed, we also build devices on flexible plastic substrates, attaining efficiencies of 21.3%. These ...
All-perovskite tandem solar cells hold the promise of surpassing the efficiency limits of single-junction solar cells; however, until now, the best-performing all-perovskite tandems have exhibited lower certified efficiency than have single-junction perovskite solar cells. A thick mixed Pb-Sn narrow...
The fabrication of scalable all-perovskite tandem solar cells is considered an attractive route to commercialize perovskite photovoltaic modules1. However, the certified efficiency of 1-cm2-scale all-perovskite tandem solar cells lags behind their small-area (approximately 0.05-cm2) counterparts2,3. ...
