Perovskite solar cells have become strong contenders in the arena of photovoltaics due to the stunning rise in their efficiency from 3 % to over 20 % in just seven years. In this time, numerous device architectures and thin film deposition methods have bee ...
A photovoltaic system including a solar cell having a hysteretic behavior; and a power device configured to extract a maximum power from the solar cell by forcing power oscillations of the power output by the solar cell. ...
A series of tri-tert-butyl zinc(II) phthalocyanines (Pcs) substituted with pyridyl, carboxyl, or picolinic acid anchoring groups on the periphery were prepared. Photovoltaic (PV) studies on these dyes were carried out revealing some interesting features. I ...
