Abstract

Arrays of thin-film solar cells based on dye-sensitised nanocrystalline oxides (DSC) promise low-cost electricity especially where continuous direct insolation is unavailable. However, the optimisation of arrays of DSC is not straightforwardbecause of the lower power levels obtained and the corresponding increased stringency needed when calculating the production tolerances permissible in the individual cells. This paper describes the first stage of project to devise and build a DSC array simulator driven solely by a phenomenological model of individual DSC behaviour at the level of infinitesimal cells. The simulator numerically extrapolates this behaviour to real finite cells andthence to a real physical array. In the process it is observedthat optimisation of infinitesimal cells is only possible when the size of the real cell is first decided, and that the relationship between the conducting oxide transparency and electrical resistance is critical for the optimisation to be effective. The results obtainedusing the simulator are comparedwith the behaviour of real test cell assemblies manufactured by STI, a DSC Licensee, andare foundto be in goodagreement. Their effects on the costs of delivered power are discussed.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
