摘　　要：针对传统光伏窗采光需求与发电量的矛盾,以及缺乏良好的季节适用性,提出了一种外推式光伏百叶窗,并对其光电耦合特性进行了数值模拟研究。研究表明:以南京地区为例,对于传统光伏窗,透明度为发电量主要影响因素,光伏窗透明度在0.4~0.6的范围内,其采光及发电的综合性能较佳;对于外推式光伏窗,倾角越大,采光质量越好,其中,外推倾角为60°的时候,发电量效果最好,全年可发电34.975 kW·h/m^(2),比传统光伏窗全年发电量增幅近80.5%。由于外推的倾角不同,全年发电量也不同,提出的外推式百叶光伏窗既能满足采光需求,又能通过逐月改变光伏百叶的倾角获取全年最大发电量,全年可发电75.66 kW·h/m^(2),比外推式光伏窗全年发电量增幅近55.7%。Aiming at the contradiction between traditional photovoltaic window lighting demand and power generation, and lack of good seasonal applicability, this paper proposes an extrapolated photovoltaic shutter, and conducts a numerical simulation study on its photoelectric coupling characteristics. Research shows: taking Nanjing as an example, for traditional photovoltaic windows, transparency is the main factor influencing power generation. When transparency of photovoltaic windows is in the range of 0.4~0.6, the comprehensive performance of daylighting and power generation is better;for extrapolated photovoltaic windows, the greater the inclination angle, the better the lighting quality. Among them, when the extrapolated inclination angle is 60°, the power generation effect is the best. The annual power generation capacity is 34.975 kW·h/m^(2), which is nearly 80.5% higher than the annual power generation of traditional photovoltaic windows. Due to the different inclination angles of the extrapolation, the annual power generation is also different. The extrapolated louvered photovoltaic window proposed can not only meet the daylighting demand, but also can obtain the annual maximum power generation by changing the inclination of the photovoltaic louver month by month. It can generate 75.66 kW·h/m^(2), an increase of nearly 55.7% compared with the annual output of extrapolated photovoltaic windows.
