An organic solar cell uses carbon-based materials and organic electronics instead of silicon as a semiconductor to produce electricity from the sun. In an organic solar cell, the photovoltaic process is the same, but carbon-based compounds are used instead of silicon as the semiconducting material. OPV cells are categorized into two classes: Small-molecule OPV cells use molecules with broad absorption in the visible and near-infrared portions of the electromagnetic spectrum. Polymer-based OPV cells use long-chained molecular systems for the electron-donating material. Most organic photovoltaic cells are polymer solar cells. Comparison of OPV cells with Silicon-based Solar cells: Silicon solar cells use crystalline silicon, while organic cells use carbon-based organic compounds applied in a thin layer to a synthetic backing. Because organic cells are made using an ink-based application and can exhibit transparentness, they usually result in a flexible solar panel that can be installed in more unique ways than traditional solar panels. Efficiency: A solar cell’s efficiency measures what percentage of incoming sunlight that hits the solar cell is converted to electricity. Crystalline silicon PV cells have laboratory energy conversion efficiencies over 25% for single-crystal cells and over 20% for multi-crystalline cells. Organic solar cells have exhibited efficiencies topping out near 11 per cent. OPVs still have a way to go before they can compete with silicon-based solar cells in terms of efficiency alone. 1 Reply Share Share Share on Facebook Share on Twitter Share on WhatsApp Cancel the best answer Leave an answerCancel replyYou must login or register to add a new answer.
