AB  - We wrote our Comment1 as a brief and concise guide to the Shockley–Queisser (SQ) model2, chiefly aiming to explain how real-world solar cells (non-concentrating, single-junction) must be related to the efficiency limits that result from the SQ model. There is a need for such a Comment, especially in the context of a widened portfolio of new very efficient solar cell materials and a rapidly growing community. As obvious from the title1, we target non-specialist readers. Such approach3 has the risk that the resulting text is unsatisfactory for specialist readers. The author of the Correspondence on our Comment4 is certainly such specialist reader. Thus, to reply to the Correspondence we need to leave the level at which we presented the topic in our Comment, to make clear that while there can be differences of opinion as how to explain the issue to the ‘perplexed’, what is written in our comment is a valid description of the SQ model.
