One of the most successful small molecule materials for organic solar cells is PCDTBT, or poly [N-9’-heptadecanyl-2,7-carbazole-alt-5,5- (4’,7’-di-2-thienyl-2’,1’,3’-benzothiadiazole)]. PCDTBT has a high molar extinction coefficient, which enables it to absorb a large amount of light in the visible spectrum.
Organic solar cells, also known as organic photovoltaics (OPVs), employ organic materials as the active layer to convert sunlight into electricity. Unlike traditional inorganic solar cells, organic solar cells utilize organic molecules or polymers that can be fabricated using low-cost, scalable solution-based processes.
For example, the block copolymer P3HT-b-PFMA has shown improved efficiency compared to P3HT homopolymers due to its improved morphology and charge transport properties . Here is a comparison (Table 1) of some novel polymers for organic solar cells. Small molecules have also been investigated as potential materials for organic solar cells.
An organic solar cell (OSC) or plastic solar cell is a type of photovoltaic that uses organic electronics, a branch of electronics that deals with conductive organic polymers or small organic molecules, for light absorption and charge transport to produce electricity from sunlight by the photovoltaic effect.
Silicon is the widely accustomed semiconductor material for commercial SCs, comprising of approximately 90 % of the current photovoltaic cell market. The most common cells involved in solar panel fabricating are cells based on GaAs. These are the oldest, and due to their well high efficiencies, these are the most used cells.
Small molecules have also been investigated as potential materials for organic solar cells. Compared to polymers, small molecules have a well-defined structure and higher purity, which can improve the reproducibility and efficiency of the solar cells.
