Due to the strongly increased concentration of carbon dioxide in the atmosphere, the European Union has set to obtain 25% amount of usable electrical energy from renewable energy sources till 2030. Most powerful of them is Solar energy, which, if efficiently used in solar cells (SC), can fulfil the energy demand of the society. Currently mostly used (up to 90%) are silicone-based SC. However, their production is expensive and complicated. Organic and hybrid SCs are fastly developing for over a decade. Over the last five years, perovskite solar cells (PSCs) reached record efficiencies (from 3.8% up to 22.7%) [Angew. Chem. Int. Ed. 2018, 57, 2554]. They have a simple construction and cheap starting materials. Despite this fact, there are several obstacles for their successful commercialization. One of them – for the hole transport is used relatively expensive p-type organic semiconductor spiro-OMETAD [Chem. Rev., 2007, 107, 1011]. Second unresolved problem is the stability of the PSCs. Currently, a lot of researchers search for the simpler synthesis methods to obtain cheap, yet efficient semiconductors. The aim of the project is to synthesize vinyl groups containing p-type organic semiconductors, for the efficient and stable perovskite solar cells.
Project funding:
Project is funded by EU Structural Funds according to the 2014–2020 Operational Programme for the European Union Funds’ Investments priority “Development of scientific competence of researchers, other researchers, students through practical scientific activities” under Measure No. 09.3.3-LMT-K-712.
Project results:
The expected result of the project – p-type organic semiconductors, able to form cross-linked structured polymers for efficient and stable perovskite solar cells.
Period of project implementation: 2018-10-01 - 2019-04-30
