A novel semi-transparent building integrated photovoltaic (BIPV) laminate was developed and introduced in this paper. It was produced by cutting standard mono-crystalline silicon solar cells into small strips and then making electrical connections between each strip before laminating the cells between two layers of glass. The overall energy performance and energy saving potential of the BIPV insulated glass unit (IGU) under real world conditions were identified through a side by side comparative study. Compared to the reference IGU, the BIPV IGU had lower solar heat gain coefficient (SHGC) but much higher U-factor. The average HVAC electricity saving of the BIPV IGU was about 10% relative to the reference IGU. Daylighting measurement and analysis were carried out to evaluate the trade-offs associated with the BIPV IGU between daylight, glare, and lighting energy use. The results indicated that the BIPV IGU is better than the reference IGU in reducing discomfort glare. However, if the most conservative viewpoint near the window is used for the assessment, a lower transmittance BIPV IGU is required to bring the overall discomfort levels below the perceptible level. Lastly, the net energy saving potential associated with the novel BIPV IGU was identified based on the power, thermal and daylighting performance. On average, the BIPV IGU saved 16.8% of the total electricity use of the room. Further studies and improvement on the energy conversion efficiency of solar cells, the optimal transmittance as well as the thermal properties would make this technology more energy-efficient and affordable.

本文开发并介绍了一种新型的半透明建筑集成光伏（BIPV）层压板。它是通过将标准的单晶硅太阳能电池切成小条，然后在每个条之间进行电连接，然后在两层玻璃之间层压电池来生产的。通过并排比较研究，确定了在现实条件下BIPV中空玻璃装置（IGU）的总体能源性能和节能潜力。与参考IGU相比，BIPV IGU具有较低的太阳热增益系数（SHGC），但具有较高的U因子。BIPV IGU的平均HVAC节能量相对于参考IGU约为10％。进行了日光测量和分析，以评估与BIPV IGU相关的日光，眩光，和照明能源的使用。结果表明，BIPV IGU在减少不适眩光方面优于参考IGU。但是，如果使用窗口附近最保守的视点进行评估，则需要较低的透射率BIPV IGU，以使总体不适水平低于可感知的水平。最后，根据功率，热量和采光性能确定了与新型BIPV IGU相关的净节能潜力。BIPV IGU平均节省了房间总用电量的16.8％。对太阳能电池的能量转换效率，最佳透射率以及热性能的进一步研究和改进将使该技术更加节能和负担得起。结果表明，BIPV IGU在减少不适眩光方面优于参考IGU。但是，如果使用窗口附近最保守的视点进行评估，则需要较低的透射率BIPV IGU，以使总体不适水平低于可感知的水平。最后，根据功率，热量和采光性能确定了与新型BIPV IGU相关的净节能潜力。BIPV IGU平均节省了房间总用电量的16.8％。对太阳能电池的能量转换效率，最佳透射率以及热性能的进一步研究和改进将使该技术更加节能和负担得起。结果表明，BIPV IGU在减少不适眩光方面优于参考IGU。但是，如果使用窗口附近最保守的视点进行评估，则需要较低的透射率BIPV IGU，以使总体不适水平低于可感知的水平。最后，根据功率，热量和采光性能确定了与新型BIPV IGU相关的净节能潜力。BIPV IGU平均节省了房间总用电量的16.8％。对太阳能电池的能量转换效率，最佳透射率以及热性能的进一步研究和改进将使该技术更加节能和负担得起。需要较低的透射率BIPV IGU，以使总体不适水平低于可感知的水平。最后，根据功率，热量和采光性能确定了与新型BIPV IGU相关的净节能潜力。BIPV IGU平均节省了房间总用电量的16.8％。对太阳能电池的能量转换效率，最佳透射率以及热性能的进一步研究和改进将使该技术更加节能和负担得起。需要较低的透射率BIPV IGU，以使总体不适水平低于可感知的水平。最后，根据功率，热量和采光性能确定了与新型BIPV IGU相关的净节能潜力。BIPV IGU平均节省了房间总用电量的16.8％。对太阳能电池的能量转换效率，最佳透射率以及热性能的进一步研究和改进将使该技术更加节能和负担得起。房间总用电量的8％。对太阳能电池的能量转换效率，最佳透射率以及热性能的进一步研究和改进将使该技术更加节能和负担得起。房间总用电量的8％。对太阳能电池的能量转换效率，最佳透射率以及热性能的进一步研究和改进将使该技术更加节能和负担得起。
