Description
The challenge of the present world is the development in the field of energy saving and renewable energy. Therefore, it is necessary to increase the share of alternative energy sources in total world production. It can be achieved by maximizing energy yields while minimizing the cost of its obtaining. Hence, the main direction of photovoltaics evolution is implementation of advanced technologies for cheap and high-efficient solar cells and modules production. To meet these expectations the major project finding is the development of a procedure of low-resistive metal oxide semiconductors production for use in all oxide heterojunction and perovskite solar cells. The material selected for the research is very promising copper (I) oxide, which is characterized by good physicochemical parameters and can constitute a structural element of the solar cell. The project consists of two tasks. The result of the first task is the “know how” of producing the thin functional layers, based on low-resistive doped metal oxides. For this purpose the simple spray-coating method will be implemented. In the second task a complete prototype device with doped copper oxide will be produced. Two variants of solar cells are considered, heterojunction thin film solar cell where copper oxide will act as an light harvester and perovskite solar cell with Cu2O holes transporting layer.
The evolved technology will contribute to the broadening of knowledge in the field of doping of oxide semiconductors. Moreover, in the long term, it can be commercialized what will reduce the production costs of solar cells and modules. Due to this, the number of photovoltaic investments will increase what will have a positive impact on environmental protection.
