Накратко на български

Перовскитните слънчеви панели се тестват с евтини графитови нанопластини, които да заменят скъпото злато при събирането на ток. Това би намалило разходите за производство и въглеродния отпечатък на технологията, правейки я по-достъпна за масова употреба.

Graphene NanoPlatelets current collectors based fully Printable Passivated Perovskite PhotoVoltaics

Photovoltaics hold the promise to solve the climate crisis, due to their eco-friendly character, as one of the renewable technologies with the lowest carbon footprint. However, the current prices and the low manufacturing throughput of Silicon solar panels (the dominant technology of the PV market) holds their widespead development across the planet. Among the different alternative PV technologies that show great promise for commercialization replacing silicon, is perovskite PVs, due to their solution processability combined with efficiencies comparable to silicon. This makes perovskite PVs ideal candidates with a potential for high throughput low cost panel manufacturing. However, the fact that high efficiency perovskite PVs repy on gold as the current collecting electrode, this makes them less competitive towards low cost (gold is expensive raw material) and high throughput manufacturing (gold requires thermal evaporation). Thus, finding an alternative printalbe low cost material to replace gold as the current collecting electrode in perovskite PVs, without compromising their performance, will consist perovskite PV superior compared to the traditional silicon solar panels. Such an demonstration would enable the widespreade development of solar panels as the major source for the generation of electricity in commercial, utility and residential scale. Additionally, the significantly lower carbon footprint of a printable current collector (compared to the thermally evaporated gold counterparts) will have a significant impact on further reducing the carbon footprint of solar panels during their manufacturing phase. Furthermore, the development of perovskite PV, will also benefit the adoption of solar panels on other fields such such portable devices, airplanes, electric vehicles, satelites, etc. due to their significantly lower weight (i.e. higher power-per-weight output) as a thin film PV technology (which does not rely on thic wafers). To achieve the afforementioned, novel graphene-based printable electrodes/current collectors, due to their high conductivity, will be developed and tested in perovskite solar cells with the aim to achieve high performances (~20% in small area cells), high operational stabilities (comparable with silicon) and significant power-per weight outputs. As a conclusion, GNPs4PVs demontrated efficiencies up to 19.2% accompanied with thermal stabilities of >1000 hours and also demonstrated the huge potential of of graphene in perovskite solar cells for high power-per-weight solar cells and towards reducing the operational temperature of these devices.

Цел на проекта

Due to their high efficiencies (>25%), low-cost and compatibility with scalable, low energy demanding fabrication techniques, perovskite solar cells (PSCs) are the most promising PV technology to replace silicon. However, there are challenges towards their commercialisation, including the low operational stability, the use of expensive components (gold) and the need for expensive, high temperature/vacuum deposition equipment. These complexities increase the manufacturing cost/carbon footprint and reduce the manufacturing throughput. A promising way to overcome these challenges is by adopting the Carbon-based PSCs (CPSCs) configuration, in which the gold electrode is replaced by a low-cost printable carbon (graphite-based) conductive film. However, due to the electronic losses at the Carbon/Perovskite interface and the high sheet resistance of graphite-based Carbon electrodes (>10 Ohm/sq), the highest reported certified power conversion efficiency (PCE) for CPSC is just 12.8%. The research carried out under this proposal aims to: 1) generate the first CPSC with certified PCE > 20% and operational lifetime comparable to commercial technologies and 2) demonstrate stable CPSC modules (100cm2) with >15% PCE. This will be enabled by exploiting novel printable Graphene Nanoplate based electrodes (replacing graphite), perovskite passivation and interfacial engineering approaches. Such an outcome would be tremendously important for the EU market and will attract the attention of industry towards commercialization. The expected outcome will enable a significant reduction in the levelized cost of electricity to 0.03 €/kWh, even below the cost of traditional energy sources. Also, a significant reduction of CO2 emissions is expected, thanks to the excellent device lifetime potential and the low energy demanding fabrication processes. Therefore, the demonstration of CPSCs with the aforementioned capabilities would represent a significant scientific and technological breakthrough.
