We present an analysis and a model for a vertical multijunction solar cell with covering lens, for which a 21% efficiency has been predicted previously. It is shown that the maximum conversion efficiency is in fact about 0.3%. The present analysis confirms our belief that back-to-back diodes should be designed into a solar cell only with great caution.
