| Fields of research/activity: | Preparation and investigation of photovoltaic (PV) structures and solar cells based on inorganic photoabsorbers and organic functional layers. Purpose of this study is preparation and investigation of the hybrid PV structures based on polycrystalline inorganic photoabsorbers CuInSe2 (CISe), CuInS2 (CIS), Cu(InGa)Se2 (CIGS), CdTe etc., where electrically conductive organic layer plays the role of the buffer layer or back-contact layer in complete PV structure. In this approach, the organic layer is considered as an alternative for the traditional buffer layer and back-contact layer in the conventional cell structure. Possible organic layers are electrically conductive polymer (ECP) layer, Zn-phthalocyanine (ZnPc) layer, ECP:C60 composite layer and ZnPc:C60 composite layer. |
| Products (if applicable): | PV structures and solar cells |
| Idea of cooperation project: | Preparation and investigation of photovoltaic (PV) structures and solar cells based on inorganic photoabsorbers and organic functional layers and composites.
For example, the following types of structures can be prepared and investigated: glass/ITO/CdS/CdTe/ECP, glass/ITO/CdS/CIS/ZnPc, glass/ITO/CdS/CISe/ECP and the similar kind of structures. Also we have an interset to prepare and investigate the hybrid stuctures based on the combination of polynanocrystalline films or nanoparticles of inorganic phophotoabsorbers with above mentioned organic semiconductors. |
| Potential partner description: | We are waiting from our partners so-called inorganic PV semistructures (such as glass/ITO/CdS/CdTe, glass/ITO/CdS/CIS or others) where we can use a functional organic layers or composite layers. Main method for the organic functional layers deposition is spin-coating. Prepared complete PV structures can be investigated in our lab and we will try to develop these structures as solar cells in close cooperation with our partners. |
