Organic Solar Cells

Review: The conversion of sunlight into electricity can be achieved using a solar cell and is one of the most attractive future soruce of energy. Silicon‐based cells, while quite efficient, are difficult and expensive to produce, a fact that drives up the cost of electricity produced using them. The alternative, organic‐based cells (see Figure) have the potential advantages of ease of processing and cheapness if their efficiency can be brought up to reasonable levels. Recent progress made and future targets in this field are reviewed. equation image
