First, a quasi-two-dimensional calculation model was established to realize the simulation of photovoltaic walls with three structural forms(ordinary wall with air layer opening, air layer closed and no air layer);combined with the experimental data, the accuracy of the two-dimensional calculation model was verified. Based on the simulation results, the suitability of different structural forms of photovoltaic walls in areas with different climatic conditions were compared and analyzed. The results of the study show that the southern China that emphasize the purpose of ventilation and heat dissipation should adopt photovoltaic walls with open air layers, and the northern regions that emphasize the purpose of heat preservation and heat insulation should adopt photovoltaic walls with closed air layers;for transitional areas, the type of photovoltaic wall should be considered comprehensively according to environmental conditions and local building conditions.展开更多
