The efficiency of solar cells based on perovskites has rapidly increased from an initial promising value of 9% in 2012 to over 22% currently, making this the fastest-advancing solar cell technology. The impressive increase in efficiency has led.Solar cells made from hybrid perovskite semiconductors have emerged only recently, yet their efficiency is already comparable to that of silicon solar cells. In contrast to the rapid progress in efficiency, our understanding of why hybrid perovskite solar cells perform so well is lacking. Charge-carrier recombination is one of the most important properties of a solar-cell.


Perovskite solar cells with record power conversion efficiency are fabricated by alloying both hybrid and fully inorganic compounds. While the basic electronic properties of the hybrid perovskites are now well understood, key electronic parameters for solar cell performance, such as the exciton binding energy of fully inorganic perovskites, are still unknown. By performing magneto-transmission.This rapid progress in perovskite solar cell research led to the increased performance and operational stability, which nevertheless remains a challenge towards the commercialization of PSC technologies. In the course of this PhD thesis, new strategies in the design of perovskite solar cells were established based on molecular engineering by addressing (1) perovskite, (2) electron transport.

Phd Thesis Perovskite Solar Cell

The stability of perovskite solar cells is a vital issue that must be addressed in further detail if perovskite PV is to become a commercially viable technology. Here, the importance of hydrophobic hole transport layers for perovskite solar cell stability is identified. Facile formation of a moisture free perovskite is achieved by combining the.

To improve the charge separation and transport efficiency in perovskite solar cells (PSCs) with a TiO 2. (SCN 2 H 4) 2 Cl 2:CH 3 NH 3 PbI 3 bulk-heterojunction cell shows much higher efficiency and better stability than the PSCs with pure CH 3 NH 3 PbI 3. The highest efficiency reaches 20.1%, which is 1.16 times that (17.3%) of the PSCs with pure CH 3 NH 3 PbI 3 and is also much higher than.

A low-cost alternative of multi-junction cell is a perovskite solar cell. The best efficient perovskite solar cell with a power conversion efficiency of 23.9% was achieved by using a complex.

Phd Thesis Perovskite Solar Cell

The past few years have seen an explosion of interest in perovskite-based solar cells (PSCs). This young technology recently surpassed market-leading silicon technology by achieving an efficiency of 23%. They are also made from cheap and clean materials. The largest roadblock that remains to PSC commercialisation is their long-term durability. At present, PSCs can maintain usable performance.

Phd Thesis Perovskite Solar Cell

The work documented in this thesis concerns the control and modification of semiconducting perovskite thin films for their use in perovksite solar cells (PSCs). PSCs are a promising new thin-film technology, offering both high solar to electricity conversion efficiencies and cheap fabrication costs. Herein, the boundaries of perovskite solar cell research are pushed further by tackling several.
