Overview and loss analysis of III–V single-junction and multi-junction solar cells

The development of high-performance solar cells offers a promising pathway toward achieving high power per unit cost for many applications. Because state-of-the-art efficiencies single-junction are approaching the Shockley-Queisser limit, multi-junction (MJ) very attractive high-efficiency cells. This paper reviews progress in III–V compound and MJ In addition, analytical results efficiency potential non-radiative recombination resistance losses presented further understanding decreasing major materials GaAs single-junction, 2-junction 3-junction shown to have 30%, 37% 47%, respectively. Although initial stage developments, low ERE values, values been improved as result several technology such device structure material quality developments. case cells, improvements sub-cells be necessary
