Numerical study of influence of protective materials on photovoltaic cell efficiency: comparison between glass and teflon



Abstract. Predicting the temperature field in protective materials can contribute to enhance performance of photovoltaic panels. Materials as Glass or Teflon, on which protective layers have been made and are often employed to protect photovoltaic cells, have an effect on heat transfer through photovoltaic cells. Teflon is known as an excellent dielectric. In this context, heat transfer was simulated by using Finite Difference Method with explicit scheme. The temperature field was computed for the two different materials. First results showed that for both studied materials, the temperature field as well as the rate of heat transfer during daytime and of cooling during night are very different. With this knowledge, engineers can design new system to improve the efficiency of solar panels that operate in non-optimal conditions.
