Tandem solar cells that pair silicon with a metal halide perovskite are promising option for surpassing the single-cell efficiency limit. We report monolithic perovskite/silicon tandem certified power conversion of 29.15%. The absorber, bandgap 1.68 electron volts, remained phase-stable under illumination through combination fast hole extraction and minimized nonradiative recombination at hole-selective interface. These features were made possible by self-assembled, methyl-substituted carbazole monolayer as layer in cell. accelerated was linked to low ideality factor 1.26 single-junction fill factors up 84%, while enabling open-circuit voltage high 1.92 volts. In air, without encapsulation, retained 95% its initial after 300 hours operation.

Abstract Perovskite solar cells (PSCs) have become a promising photovoltaic (PV) technology, where the evolution of electron‐selective layers (ESLs), an integral part any PV device, has played distinctive role to their progress. To date, mesoporous titanium dioxide (TiO 2 )/compact TiO stack been among most used ESLs in state‐of‐the‐art PSCs. However, this material requires high‐temperature sintering and may induce hysteresis under operational conditions, raising concerns about its use toward commercialization. Recently, tin oxide (SnO ) emerged as attractive alternative ESL, thanks wide bandgap, high optical transmission, carrier mobility, suitable band alignment with perovskites, decent chemical stability. Additionally, low‐temperature processability enables compatibility temperature‐sensitive substrates, thus flexible devices tandem cells. Here, notable developments SnO perovskite‐relevant ESL are reviewed emphasis placed on various fabrication methods interfacial passivation routes champion Further, techno‐economic analysis materials for large‐scale deployment, together processing‐toxicology assessment, is presented. Finally, perspective how can be instrumental successful module perovskite‐based cell manufacturing provided.

We demonstrate a monolithic perovskite/CIGS tandem solar cell with certified power conversion efficiency (PCE) of 24.2%. The still exhibits photocurrent mismatch between the subcells; thus optical simulations are used to determine optimal device stack. Results reveal high potential optimized reaching short-circuit current density 19.9 mA cm–2 and 32% PCE based on semiempirical material properties. To evaluate its energy yield, we first CIGS temperature coefficient, which is at −0.38% K–1 notably higher than one from perovskite subcell (−0.22% K–1), favoring in field operation elevated temperatures. Both single-junction cells, however, significantly outperformed by combined device. enhancement output more 50% case results for describe guidelines toward 30% PCE.

Abstract Large datasets are now ubiquitous as technology enables higher-throughput experiments, but rarely can a research field truly benefit from the data generated due to inconsistent formatting, undocumented storage or improper dissemination. Here we extract all meaningful device peer-reviewed papers on metal-halide perovskite solar cells published so far and make them available in database. We collect over 42,400 photovoltaic devices with up 100 parameters per device. then develop open-source accessible procedures analyse data, providing examples of insights that be gleaned analysis large dataset.
