摘要： Perovskite solar cells (PSCs) are currently a centre of attraction for their excellent photovoltaic properties and low fabrication cost. The ef?ciency of PSCs has reached up to 25% which is comparable to silicon-based solar cells, making them the fastest improving photovoltaic technology. All state-of-the-art PSCs are usually fabricated in inert environment conditions such as in nitrogen-?lled glovebox. In this study, we have fabricated well known conventional n-i-p and inverted p-i-n structures of PSCs having methylammonium lead iodide (MAPbI3) as a perovskite photoactive layer in ambient conditions and provided a comparative study on their photovoltaic properties. The highest power conversion ef?ciency (PCE) for n-i-p and p-i-n structures were found to be 16.79% and 8.06% respectively under AM 1.5 G one-sun illumination conditions (100 mW-cm?2). In addition, to investigate the device stability, the variation of short-circuit current density (JSC) under continuous illumination on both structures has been investigated.
