6 FAQs about [Perovskite cells do not require silicon]
Are perovskite solar cells better than thin-film solar cells?
Perovskite solar cells emerged from the field of dye-sensitized solar cells, so the sensitized architecture was that initially used, but over time it has become apparent that they function well, if not ultimately better, in a thin-film architecture.
Could perovskites push solar cell efficiencies beyond current limits?
Tandem structures combining perovskites with other materials could push solar cell efficiencies beyond current limits. As production scales up, PSCs are expected to be used in diverse markets, from portable electronics to utility-scale solar farms.
Can perovskite be used as a tandem solar cell?
Oxford PV found less of an impact with the production of perovskite on silicon modules (i.e., a tandem photovoltaic cell) than with silicon only. With this in mind, in addition to the benefits in efficiency, the company has scaled up the commercial production of perovskite–silicon tandem solar cells (see Figure 1).
