While inorganic photovoltaic cells utilize crystalline elements as a light absorber, organic photovoltaic cells utilize molecules or polymers to convert sunlight into electricity.
What are the main differences between organic and inorganic photovoltaic solar cells?
One of the biggest differences between silicon photovoltaics and organic photovoltaics (OPV) is in their physical structure – organic cells are made with compounds that are typically dissolved in ink and printed onto thin plastics, which means that OPVs can be flexible and incorporated into more places or structures …
What are inorganic solar cells?
The inorganic semiconductor materials used to make photovoltaic cells include crystalline, multicrystalline, amorphous, and microcrystalline Si, the III-V compounds and alloys, CdTe, and the chalcopyrite compound, copper indium gallium diselenide (CIGS).
How are organic solar cells made?
Organic solar cells are made with organic semiconductors, which follow the working principle that organic semiconductors may produce electrons and holes that are bound in excitons while separation of the electron and hole occurs in the interface (the junction of electrodes and conductive polymers).
What is perovskite made of?
Perovskite is a mineral composed of calcium titanium oxide (CaTiO2) discovered by a Russian scientist, Gustav Rose, in 1839 and the research was further carried out by Russian mineralogist Lev Perovski therefore this mineral was named as Perovskite.
What are the types of organic solar cells?
Based on their method of production, organic polymeric-based solar cells can be further classified into three types: organic bulk heterojunction thin-film solar cells, organic tandem solar cells, organic DSSCs.
What is the efficiency of organic solar cells?
Organic photovoltaics have achieved efficiencies near 11%, but efficiency limitations as well as long-term reliability remain significant barriers. Unlike most inorganic solar cells, OPV cells use molecular or polymeric absorbers, which results in a localized exciton.
