Organic Dye Solar Panels

Dye sensitised solar cells.

Organic dye solar panels.

Organic solar cells are made of cheap and abundant. A perovskite solar cell psc is a type of solar cell which includes a perovskite structured compound most commonly a hybrid organic inorganic lead or tin halide based material as the light harvesting active layer. Organic dye in zinc oxide interlayer stabilizes and boosts the performance of organic solar cells date. 5 7 in dsscs the photosensitizer is one of the most important components influencing solar cell performance because the choice of sensitizer determines.

1 4 recently solar energy to electricity conversion efficiencies as high as 11 under am 1 5 g irradiation have been attained with dsscs. The molecules used in organic solar cells are solution processable at high throughput and are cheap resulting in low production costs to fabricate a large volume. August 16 2019 source. Dye sensitized solar cells are a hybrid organic inorganic technology that uses small molecule absorber dyes.

Over the last decade dye sensitized solar cells dsscs have attracted much attention because these unconventional solar cells exhibit high performance and have the potential for low cost production. With an efficiency of around 11 and low cost production this technology has the potential to compete on the commercial market. Combined with the flexibility of organic molecules organic solar cells are potentially cost effective for photovoltaic applications. The basic scheme of a dssc is shown in fig.

Perovskite materials such as methylammonium lead halides and all inorganic cesium lead halide are cheap to produce and simple to manufacture. The organic dyes with near infrared light absorption are designed to improve the solar to electricity conversion efficiency by extending the absorption threshold of the organic dyes to the near infrared regions which accounts approximately 45 of the total solar energy. These dyes adsorb onto a suitable electron accepting material such as titanium dioxide or zinc oxide along with an electrolyte to regenerate the dye. The solar method is a variation of natural dyeing since both call for the extraction of color from such vegetable materials as wild or cultivated flowers berries tree bark and herbs.

These are not purely organic solar cells but are made of a hybrid of organic and inorganic semi conducting materials. Dye sensitized solar cells are closely related to organic solar cells and belong to the thin films. This cell technology is currently amongst the most efficient third generation solar cells. They do this by building their own organic solar cells and measuring the photovoltaic devices performance based on power output.
