建立了基于菲涅耳透镜的聚光式太阳能光伏/热系统的一维稳态传热模型，计算并比较了6种不同结构的热效率、电效率和火用效率。分析和结果表明：太阳能光伏/热系统可以用很少的电能获得热能；虽然增加玻璃覆盖层可以减少热损失，但增加光学效率和系统火用效率；在恶劣的环境条件下，透镜和吸收体之间应该有绝缘，这可以提高热效率而不影响电能。
In this paper the one dimensional steady heat transfer model of concentrating solar pho- tovoltaic/thermal system based on Fresnel lens was established.The thermal,electricity and exergy efficiency of six different structure were calculated and compared.The analysis and results present: the solar photovoltaic/thermal system can get thermal energy for sacrifice of little electricity energy; although increasing glass cover can decrease thermal loss,but increase optical efficiency and system exergy efficiency;in terrible ambient conditions there should be insulation between lens and absorber, this can enhance thermal efficiency and not affect electricity energy.
