摘要

荧光太阳集光器在光伏建筑一体化方面的潜在应用受到了广泛关注。本文采用CsPbBr

纳米晶作为集光器的发光中心，采用硫醇-烯聚合物作为集光器的透明光波导基质。通过荧光发射谱、吸收谱以及荧光寿命谱等对集光性能进行研究，发现将CsPbBr

纳米晶掺入硫醇-烯聚合物后，发光峰位蓝移了11 nm、半高宽展宽了20.4 nm，这可归因于硫醇-烯聚合物基质的介电约束效应。同时，硫醇-烯聚合物基质大幅提高了CsPbBr

纳米晶的发光稳定性。当CsPbBr

纳米晶在硫醇-烯聚合物基质中的掺杂浓度为5.6%时，荧光太阳集光器的集光效率可达8.9%。采用商用的多晶硅太阳能电池耦合在荧光太阳集光器的边缘，在标准AM1.5的太阳光照条件下，器件开路电压为0.47 V，短路电流密度为7.14 mA/cm

，填充因子为24.01%，光电转换效率为2.30%。

Abstract

Luminescent solar concentrator(LSC) attracts extensive attention due to the potential application in the building integrated photovoltaics. In this work

the CsPbBr

nanocrystal is chosen as the luminescent center and the thiol-ene polymer is used for the transparent optical waveguide matrix of LSC. The photoluminescence emission spectra

absorption spectra

and time-resolved emission spectra are performed to evaluate the optical efficiency

respectively. It is found that the emission peak blue-shifts by 11.0 nm and the full width at half maximum(FWHM) widens by 20.4 nm

which can be attributed to the dielectric screen effect of thiol-ene polymer matrix. Meanwhile

the introducing thiol-ene polymer matrix can greatly improve the photoluminescence emission stability of CsPbBr

nanocrystals. When the amount of CsPbBr

nanocrystals in the thiol-ene polymer matrix is 5.6%

the corresponding optical efficiency of LSC can reach 8.9%

which is higher than that of nanocrystals-based LSC reported in most previous studies. Further

the commercial polycrystalline silicon solar cell is designed to install in the edge of an LSC. Under the standard AM1.5 solar simulator

the device demonstrated the attractive attributes of open-circuit voltage of 0.47 V

short-circuit current density of 7.14 mA/cm

fill factor of 24.01%

and high power conversion efficiency up to 2.30%.
