Hybrid perovskite/silicon tandem solar cells offer low-cost alternatives to the commercially established silicon solar cells. In this thesis, we present the material and device optimizations of the subcells that can be ...

Organic-inorganic lead halide perovskite solar cells (PSC’s) research has seen most notable progress in the field of photovoltaics (PV). The very first PSC was reported in the year 2009 with efficiency of 3.8%, which rapidly ...

The growing demand for energy is an important issue for the existence and development of humankind. In order to reduce the impact of conventional energy sources on the environment, attention should be paid to the development ...

In tandem solar cells two or more solar cells share the solar spectrum. The structure consists of two sub-cells on top of each other, with the top cell absorbing the blue photons and the bottom cells absorbing the red ...

Several oxides are non-toxic, stable, and can be deposited using inexpensive techniques on a variety of substrates. There is a compelling case for use of oxide in photovoltaics, referred to as “all-oxide photovoltaics”. ...
