With rapid progress in a power conversion efficiency (PCE) to reach 25%, metal halide perovskite-based solar cells became game-changer photovoltaic performance race. Triggered by the development of solid-state perovskite cell 2012, intense follow-up research works on structure design, materials chemistry, process engineering, and device physics have contributed revolutionary evolution be strong candidate for next-generation energy harvester. The high combination with low cost processes are selling points this over commercial silicon or other organic inorganic cells. characteristic features may enable further advancement PCE beyond those afforded cells, toward Shockley-Queisser limit. This review summarizes fundamentals behind optoelectronic properties materials, as well important approaches fabricating high-efficiency Furthermore, possible strategies enhancing limit discussed.

Monolithic perovskite/silicon tandem solar cell with >29% efficiency by enhanced hole extraction

Science, Год журнала: 2020, Номер 370(6522), С. 1300 - 1309

Опубликована: Дек. 10, 2020

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.

If perovskite solar cells (PSCs) with high power conversion efficiencies (PCEs) are to be commercialized, they must achieve long-term stability, which is usually assessed accelerated degradation tests. One of the persistent obstacles for PSCs has been successfully passing damp-heat test (85°C and 85% relative humidity), standard verifying stability commercial photovoltaic (PV) modules. We fabricated damp heat-stable by tailoring dimensional fragments two-dimensional layers formed at room temperature oleylammonium iodide molecules; these passivate surface electron-selective contact. The resulting inverted deliver a 24.3% PCE retain >95% their initial value after >1000 hours conditions, thereby meeting one critical industrial standards PV

Engineering perovskites with anions The bandgap of the perovskite top layer in tandem silicon solar cells must be tuned to ∼1.7 electron volts. Usually, cation composition is varied because bromine-rich anion compositions wide bandgaps are structurally unstable. Kim et al. show that by using phenethylammonium as a two-dimensional additive, along iodine and thiocyanate, films can stabilized. A cell delivered >26% certified power conversion efficiency, device maintained 80% its initial efficiency >20% after 1000 hours under illumination. Science , this issue p. 155

Recently, perovskite solar cells (PSCs) have attracted much attention owing to their high power conversion efficiency (25.2%) and low fabrication cost. However, the short lifetime under operation is major obstacle for commercialization. With efforts from entire PSC research community, significant advances been witnessed improve device operational stability, a timely summary on progress urgently needed. In this review, we first clarify definition of stability its significance in context practical use. By analyzing mechanisms established approaches improvement, summarize several effective strategies extend layer-by-layer sequence across PSC. These are discussed contexts chemical reactions, photo-physical management, technological modification, etc., which may inspire future R&D stable PSCs. Finally, emerging standards with respect testing reporting summarized discussed, help reliable data circulate community. The main target review gaining insight into PSCs, as well providing useful guidance further by rational materials processing fabrication, would finally promote commercialization cells.

Inserting an ultrathin low-conductivity interlayer between the absorber and transport layer has emerged as important strategy for reducing surface recombination in best perovskite solar cells. However, a challenge with this approach is trade-off open-circuit voltage (Voc) fill factor (FF). Here, we overcame by introducing thick (about 100 nanometers) insulator random nanoscale openings. We performed drift-diffusion simulations cells porous contact (PIC) realized it using solution process controlling growth mode of alumina nanoplates. Leveraging PIC approximately 25% reduced area, achieved efficiency up to 25.5% (certified steady-state 24.7%) p-i-n devices.
