Perovskite solar cells have made an impressive entrance onto the photovoltaic research agenda. To run the full course to commercialisation, a compelling market advantage needs to be shown over the present silicon and inorganic thin-film market incumbents.
Potential advantages might be ease of deposition, flexibility and transparency or conversion efficiency, particularly when implemented as all-perovskite or hybrid tandem cells in conjunction with silicon or CIGS. The economics of cell manufacturing are discussed, with the ease of forming tandems emerging as potentially the most readily exploitable of perovskite cell attributes.
Rapidly improving research results with silicon/perovskite tandem cells suggest that higher efficiency than possible with silicon alone will soon be demonstrated. This makes stability the key issue likely to inhibit market introduction, with silicon or CIGS module manufacturers unlikely to be willing to compromise stability for improved performance. An all-perovskite thin-film tandem structure offering higher efficiency than silicon presents another option where stability may become less of an overriding issue.
