Накратко на български
Перовскитните слънчеви клетки изискват нови органични материали за транспорт на положителни заряди, които да бъдат по-евтини и проводими. Това ще помогне за повишаване на ефективността и издръжливостта на панелите при влага.

New Hole-Transport Materials to Enhance Perovskite Solar Cells
The world demand for energy is growing intensively and continuously. This creates needs for environmentally-clean energy resources like solar energy, which huge potential remains unexploited. Silicon-based solar cells consist of more than 90% of commercial photovoltaic devices. However, emerging lead-halide perovskite solar cells are a potentially-revolutionary new photovoltaic technology with its advantages like: low-cost, easy-to-assemble, flexible, lightweight, semi-transparency, solution processability and freedom of design in terms of colours and shapes. This should lead to higher adoption of solar technology. Great advances in recent years have arisen mainly through developments in the light-absorbing perovskite layer, and this has created a need to develop other component materials in order to further increase device efficiency and stability. To enable the full potential of the technology to be realised progress is needed to tackle these points: 1. One of the conducting layers in the cells, the “organic hole-transport material”, currently shows poor conductivity and/or high synthesis cost and improved materials are required. 2. Poor moisture stability of the perovskite limits device lifetime. Discovery of the hole-transport material that are both efficient and cost effective while do not decrease device stability as currently used spiro-MeOTAD remains one of the biggest challenges in the field of perovskite solar technology.

Цел на проекта
The extraordinary recent progress in lead-halide perovskite-based solar cells has largely been based on the properties and processing of the perovskite layer. Inevitably some cell performance limitations are now linked with other component materials, where progress is required to enable the full potential of the technology to be realised:1.Poor charge mobility and/or high synthesis cost of current organic hole-transport materials (HTMs) incorporated into cells, limiting current collection and cost.2.Poor moisture stability of the perovskite, limiting device lifetime.3.Toxicity of Pb, that could preclude some application areas for the devices, or poorer light harvesting if Pb is replaced by Sn.This proposal tackles all three of these points, through design, synthesis, characterisation, in-house testing and application of new organic hole-transport materials with enhanced properties. This builds upon materials previously developed in the host group, which have already shown excellent promise in perovskite cells. Crucially, the project will provide a complementary experience for the Fellow that adds to his previous outstanding contributions during his PhD to the area of organic light-emitting diodes (OLEDs). His PhD experience in preparing emissive materials for these electricity-in-light-out OLEDs will now be extended to light-in-electricity-out solar cells. This will give the Fellow a superb overview of both fields such that he can use the synergies in materials development across the whole area as a springboard for his subsequent career.
