Manufacturing Processes for the Creation of 15% Power Conversion Efficiency Inorganic Inorganic-Organic Perovskite Solar Cells

Abstract

Solar cell research aims at a gradual increment on the overall power conversion efficiency, looking into the possibility of an increment on the output current of the device. This research discusses the different methods applied during experimentation allowing for the reach of higher efficiency, explaining the effects each method had on the different samples used. Some of the methods to be discussed are some conventional methods in the creation of perovskite solar cells such as sonication, spin spin-on doping, annealing, and contact creation. In accordance to the methods used, a power conversion efficiency of 15.2% was obtained, as well as an open circuit voltage (Voc) of 1.065 V, a short circuit current (Isc) of 1.99 mA, a fill factor (FF) of 50.4%, a short circuit current density (Jsc) of 28.2 mA/cm2, and a shunt resistance of 3.3 kΩ. Each sample is discussed in order to provide a wider view on the positive and negative aspects of each method applied.
