摘要
限于太阳能电池本身的光谱响应特性,其只能利用入射光谱中的低频部分光子,造成了光能的损失,因而转化效率较低。为此在电池的上表面引入"转光层",其中包含的转光材料首先吸收电池光谱响应较差的短波长光子(一般300～500nm),再发射出光谱响应性好的波长较长的光子,提高电池的光谱响应性,进而提高太阳能电池的转化效率。近年来,随着转光材料的丰富和性能的提高,应用转光层来提高太阳能电池效率的研究取得了显著的成果,但是距离其工业化应用仍有很多难题亟待解决。
Limited to the solar response characters of the solar cells,only a part of low frequency photons can by utilized,which leads to low photoelectrical conversion efficiency.In order to enhancing the spectral response of solar cells,a luminescence conversion layer including luminescence materials,was introduced above the solar cells.The layer absorbed photons,typically in the 300～500nm range,and reemited them at a longer wavelength where the solar cells perform a better response,so the conversion efficiency was improved.As the enhancing in the performances of the luminescence materials,more and more prominent achievements appeared in recent years,however,there are still many difficulties need to be solved to achieve industrial application.
