Abstract
In the last decade, Perovskite based solar cells have seen massive enhancement, as
opposed to conventional silicon (Si) based solar cells. As a result, its research has
attracted a lot of attention in recent times. The material, still being under extensive
research, has shown much changes in power conversion efficiency due to factors such
as thickness, irradiance, temperature, and etcetera.
This thesis looks into the effect of different types of optical materials if used as contact
materials on the open-circuit voltage, short-circuit current and power conversion
efficiency, in the case of a perovskite/Si tandem solar cell. The software used for this
study is GPVDM software. Built-in electrical parameters have been used in the
simulation procedure and the materials changed within the layers to see the effect. The
simulations utilised Maxwell-Boltzmann analysis to perform the task. The results
show that the type of contact material affects the efficiency, and that different oxides
give varying efficiencies. Metal contacts showed better performance when used as
back contact, while oxides were more efficient on the front. The work also compares
the performance of a tandem cell to the performance of a simple silicon base solar
cell, where the results indicate improved performance for the tandem cells. This study
will aid in understanding how perovskite/Si tandem cells behave in terms of its contact
materials, so that more enhancement can be achieved and improved upon in further
studies.
