| Summary: | Sustainable energy development strategies typically involve three major
technological changes, namely energy savings, improvement efficiency of energy
production, and replacement of fossil fuels as main energy input. Solar cell is one
of many renewable energy sources that able to maximize energy needs in
developing countries. Solar cell generation potentially developed is perovskite solar
cell (PSC). PSC is 3rd generation of solar cell utilizing perovskite material as light
absorbing materials. Primary cell components of PSC consist of photoanode,
perovskite, holes transport layer, and metal electrode. Photoanode in PSC acts as a
transmission electron generated layer from the perovskite to external circuit to
generate electric energy. TiO2 is the best electron transporting material applied in
PSC due to high photocatalyst activity. However, high charge recombination in
TiO2 can degrade PSC performance In this literature, manipulation of
characterization TiO2 by doping Fe aims to optimize power conversion efficiency
of PSC.
The literature study is carried out by analyzing various information that related to
characterization result of perovskite solar cell using Fe doped TiO2 as photoanode
for synthesizing structure and optimizing TiO2 synthesis process in order to
increasing PSC performance. The data on changing characterization of TiO2 after
adding Fe dopant is collected and analyzed the influence on alteration PSC power
conversion efficiency.
The result of data collection and analysis information from various literatures show
doping Fe in TiO2 is affecting structure and band gap energy of TiO2 and PSC
performance. In working to enhance conversion energy efficiency in PSC, it is
necessary to optimize the synthesis process parameter of TiO2 layers and content of
Fe dopant in TiO2. PCE of perovskite solar cell is increased by doping Fe 1%mol
in TiO2 due to alteration TiO2 characteristic, namely decreasing crystallite size and
band gap energy TiO2 resulting in decreasing charge carrier recombination.
Increasing Fe content in TiO2 further can alleviate PCE due to formation of oxide
on surface TiO2 that acts as recombination center. |
