| Outline of Annual Research Achievements |
The project consist of four (4) work packages (WP) in order to discover the best suitable carbon xerogel matrix for perovskite scaffolding in solar cells:
A) Synthesis and characterization of CX raw materials. Energy consumption studies. COMPLETED
B) Ink formulation and deposition of CX thin film. Characterization as HTL material. COMPLETED
C) Assembly of PVK based solar cells using CX based HTL and photovoltaic characterization. ON-GOING
D) Long term stability measurements of photovoltaic cells at maximum power point. WAITING RESULTS FROM WP-C

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
A) Synthesis and characterization of CX raw materials. Energy consumption studies. COMPLETED
Carbon xerogels (CX) were synthesized in the pH range of 4.5 - 6.5. An electric energy consumption study was carried out using the conventional heating on silicone oil
bath. Characterization of CX thin films consisted of 4-probe conductivity measurements and profilometry.
B) Ink formulation and deposition of CX thin film. Characterization as HTL material. COMPLETED.
MAPbI3 ink was embeded in CX thin films and used as probe compound for XRD study and crystallite size analysis. Transient photoluminiscence of MAPbI3 embeded in CX was recoreded and analysed.

| Strategy for Future Research Activity |
WP-C) Assembly of PVK based solar cells using CX based HTL and photovoltaic characterization. ON-GOING.
First full devices consisting of TiO2/ZrO2 and CX thin films stack and embeded perovskite are being currently prepared and characterized.
WP-D) Long term stability measurements of photovoltaic cells at maximum power point. WAITING RESULTS FROM WP-C
