Abstract
A novel parallel multijunction solar cell is described which allows fundamental radiative recombination limits upon photovoltaic cellenergy conversion efficiency to be approached more closely in good quality material than possible in a single‐junction device. However, the real advantage arises for poor quality material with the structure shown to be particularly tolerant of both impurity and grain boundary effects. A novel implementation approach is described for potentially high‐performance, low‐cost, thin‐film polycrystallinesilicon solar cells.
