  7. Abstract:
  8. Nowadays by fast growing the population and development of countries, the demand of energy is increasing rapidly. Solar energy is one of the most reliable and environment friendly source of energy. Photovoltaic modules (PV) are such a solar systems that is able to convert solar energy into electrical energy. However, some parameters such as increasing cell temperature and dust accumulation can reduce the PV modules efficiency. Increasing the cell temperature reduce the capability of electrical production of cells and dust accumulation is an obstacle for solar radiation absorption. As a result, in this research tempt to solve these problems by building a new device for PV modules. In this study, at the first step, the effect of dust deposition density on the electrical efficiency of PV module at different operating conditions is numerically investigated. At the second step, the built device for PV module is experimentally studied. Based on the numerical simulation, the electrical efficiency of PV module is highly affected by dust deposition, for instance, at the solar radiation of 700 W/m2 by increasing the dust deposition density from 0 gr/ m2 to 8 gr/ m2 the electrical efficiency reduces 26.36%. In addition, based on the numerical results, for the first time a correlation for electrical efficiency reduction of PV modules based on the dust deposition density is obtained. Furthermore, the experimental results reveals that, the PV module with using designed device has higher electrical efficiency compare to commercial PV module. However, the efficiency of proposed device is lower than a PV module with clean surface
