Abstract :

As fossil fuels cause environmental problems and begin to become depleted, research into developing renewable energy is on the rise. As fossil fuels begin to deplete and the cost of energy rises, there is more and more need for a renewable, clean energy source. One such possible alternative are OSC . Experimental results have reported 8.3% efficiency in lab tests. The development of OSC efficiency is an important step in reducing our carbon footprint. The absorption of photons is not a problem in most OSC because normally 96% of light is absorbed and organic semiconductors have high absorption coefficients even for very thin specimen. After the photons are absorbed, an exciton consisting of a hole and an electron with a binding energy of 0.1 - 1.4 eV is formed. In this article, three different models for the bimolecular recombination of solar cells are explored and a simulation is run and compared to experimental results.
