Low temperature solution process-able Perovskite solar cells are highly desirable for future photovoltaics. Chemical root was utilized to synthesize and optimize mixed halide based MAPbIBr2 light absorber perovskites on electron transport layer (ETL) of TiO2 nano particles in ambient atmosphere. For the first time all synthesis work was performed i...

Question
I made perovskite via one and two step methods but layer is too thin and absorption is also low.
Question
I'm trying to soluble PbI2 and PbBr2 in DMF and DMSO but in both solvents even after heating forms precipitates.
Question
I want to prepare compact TiO2 layer for solar cell using mildy acidic TTIP as a precursor and Ethanol as a solution but after stirring still get precipitation. I followed reported literature but still getting precipitation. 
Question
From Absorbance Vs energy plan or absorbance Vs wavelength plot. I am searching but appropriate answer was't found. 
Like that
Question
For perovskites solar cell. I want to know about how much concentration/ ratio we will take.
Question
If i want to dope perovskite material to enhance its stability and photovoltic properties. What rules I have to follow in addition to the Gouldmith rule ?.
