Abstract

A low-cost Si nanowire array/perovskite hybrid solar cell is proposed and simulated. The solar cell consists of a Si p-i-n nanowire array filled with CHNHPbI, in which both the nanowires and perovskite absorb the incident light while the nanowires act as the channels for transporting photo-generated electrons and holes. The hybrid structure has a high absorption efficiency in a broad wavelength range of 300~800 nm. A large short-circuit current density of 28.8 mA/cm and remarkable conversion efficiency of 13.3% are obtained at a thin absorber thickness of 1.6 μm, which are comparable to the best results of III-V nanowire solar cells.

摘要

提出并模拟了一种低成本的硅纳米线阵列/钙钛矿混合太阳能电池。该太阳能电池由填充有CHNHPbI的硅p-i-n纳米线阵列组成，其中纳米线和钙钛矿都吸收入射光，而纳米线充当传输光生电子和空穴的通道。这种混合结构在300~800nm的宽波长范围内具有高吸收效率。在吸收层厚度为1.6μm时，获得了28.8mA/cm²的大短路电流密度和13.3%的显著转换效率，这与III-V族纳米线太阳能电池的最佳结果相当。
