The “Development of Semi-Transparent Bifacial Thin Film Solar Cells for Innovative Applications” benefits from a 999372 € grant from Iceland, Liechtenstein and Norway through the EEA Grants. The aim of the project is to develop a new approach based on novel materials and structures and production technologies, which are the key to further increase the share, and range of applications of PV in areas with sub-average sunlight, including Baltic and Nordic countries. Therefore, development of resource saving, cost-effective and efficient PV devices is a primary challenge of this project. Project contract with the Research Council of Lithuania (LMTLT) No is S-BMT-21-1(LT08-2-LMT-K-01-003). The Department of Materials and Environmental Technology, Tallinn University of Technology has received funding from Estonian Research Council project PRG627 “Antimony Chalcogenide Thin Films for Next-Generation Semi-Transparent Solar Cells Applicable in Electricity Producing Windows”, the Estonian Centre of Excellence project TK141 (TAR16016EK) “Advanced Materials and High-Technology Devices for Energy Recuperation Systems”, the European Union's Horizon 2020 programme under the ERA Chair project 5GSOLAR grant agreement No 952509 and PSG689 “Bismuth Chalcogenide Thin-Film Disruptive Green Solar Technology for Next Generation Photovoltaics”. Institute of Solid-State Physics, University of Latvia has received funding from the European Union's Horizon 2020 Framework Programme H2020-WIDESPREAD-01-2016-2017-Teaming Phase 2 under grant agreement No. 739508, project CAMART. The authors thank Dr Tadas Malinauskas and Dr Valdek Mikli for their support in preparation and characterization of the samples. Antimony sulphide (Sb2S3) is a promising candidate for semi-transparent and tandem solar cells owing to its suitable optoelectronic properties. However, the applications of Sb2S3 solar cells are rather limited by their low power conversion efficiencies (PCEs) and use of expensive hole transport materials (HTMs). Furthermore, HTMs like P3HT ...
