All-perovskite tandem solar cells have been at the forefront of perovskite research, offering transformative potential for the solar photovoltaic (PV) industry. Our latest review paper, “Recent Progress in All-Perovskite Tandem Solar Cells: Redefining Limits,” published in Progress in Materials Science, provides a comprehensive overview of the most recent breakthroughs and emerging trends in this rapidly advancing field. I extend my sincere thanks to all co-authors for their valuable contributions in making this work possible.

🔓 Unlocking the Power of Passivation in Perovskite Silicon Tandem Solar Cells Together with PV researchers from the University of Freiburg and KAUST (King Abdullah University of Science and Technology), Juliane Borchert's research group on #perovskites proved that surface passivation of perovskite top cells is possible in combination with today's industry standard for silicon solar cells. Those solar cells have a textured, pyramid-like surface and a high-quality passivation on the consequently also uneven perovskite surface had not yet been accomplished. The findings have been published in Science Magazine. Main author Oussama ER-RAJI and his colleagues in addition discovered that the passivation affects the entire perovskite layer – unlike silicon, where surface treatment only influences the upper layers – leading to further efficiency improvements. Co-author professor Stefan Glunz explains: “Surface passivation of solar cells is not just a nice-to-have feature; it is an essential booster for their efficiency and stability. For today’s silicon solar cells, surface passivation was the key for high efficiencies in industrial production, and it is encouraging that the PV industry will benefit from these positive effects for perovskite silicon tandem solar cells as well.” 🔗 Read the press release: https://lnkd.in/e-EbdHNx 🔗 Directly to the scientific paper: https://lnkd.in/ea6qJH7M

On a pleasant afternoon in Shenzhen, world leaders in kesterite (Cu₂ZnSn(S,Se)₄, CZTSSe) solar cell research gathered for a spirited discussion: How can we push this earth-abundant and sustainable solar absorber toward commercially competitive efficiency? To answer this, all group leaders contributed their raw data on the best-performing cells, enabling a collective analysis of the key electrical parameters by first-author Shreyash Hadke. The results, now published in Nature Communications, provide an important perspective. 🔎 What we found: ·      The voltage losses in the radiative limit (due to bandgap fluctuations and Urbach tails) have largely been overcome — #CZTSSe is now comparable to commercial #CIGS devices. ·      However, the main bottleneck remains non-radiative recombination at deep defect states and grain boundaries. The recombination parameter J₀ is still 4–6 orders of magnitude higher than in CIGS, meaning significant efficiency is still lost. ·      The #pathway forward will require addressing Sn-related defects, suppressing grain boundary recombination, and leveraging strategies like synergistic alloying, gradient bandgap engineering, and advanced passivation. ⚡ With these advances, we believe #kesterite solar cells can move beyond the current ~15% milestone and approach the >20% efficiency needed for commercial viability — unlocking their potential for flexible, indoor, and building-integrated photovoltaics. This study underscores the value of #opencollaboration and #shareddata in accelerating progress toward sustainable solar technologies.
