| Summary: | Petroleum and coal are non-renewable energy sources and are the primary sources
of energy in Indonesia. However, their reserves are diminishing every day.
Additionally, the use of these sources as fuel for vehicles and steam power plants
is a significant contributor to carbon emissions in Indonesia, which contradicts the
government's commitment to implementing 'Indonesia Net Zero Carbon 2060'.
Many new renewable energy developments are currently underway that are cleaner
and more environmentally friendly than steam power plants, such as solar power
plants. Indonesia lies on the equatorial line, which caused the sun shine all years
long. Therefore, the use of solar power as a power plant is a viable option and
considerable potential in Indonesia.
A solar cell is a device that converts sunlight radiation into electricity. This research
is focused on the development of perovskite solar cells (PSCs) due to their
significant efficiency improvements compared to previous generations of solar cells.
However, PSCs still face stability problems, and various factors can affect their
stability, including the type of perovskite used, the selection of the electron
transport layer (ETL), and the relative humidity. This research aimed to determine
the best ETL to be used on solar cells with MAPbI3 or methylammonium lead
iodide perovskite. The ETL types used were titanium diisopropoxide, thiourea
modified tin oxide, and colloidal tin oxides derived from thermofisher scientific. In
addition, the effect of temperature annealing of thiourea modified tin oxide on the
performance of the solar cell was also investigated.
This research demonstrates that addition of thiourea to SnO2 resulted in better PSCs
performance compared to the use of ETL derived from titanium diisopropoxide or
colloidal tin oxide. Furthermore, after varying the SnO2 annealing temperature to
180°C, 200°C, and 220°, the results of this work show that the optimal performance
of PSC was achieved when the SnO2 was annealed at 200°C, which produced an
efficiency of 9% , fill factor of 51%, Voc of 1.018 V, Jsc of 17.36 mA/cm2, and
hysteresis index of 0.091. |
