Claims10
An agricultural structure comprising a photovoltaic device provided on the structure's roof and/or provided as a roof panel, the photovoltaic device comprising a transparent or semitransparent film comprising or consisting of at least one perovskite material absorbing light within the photosynthetically active radiation (PAR) spectrum,
- wherein the at least one perovskite material is MAnFA1-nPb(IxBr1-x)3, wherein variable x is 0.2-0.3 and variable n is 0.2-0.3;
- or CsnFA1-nPb(IxBr1-x)3, wherein variable n is 0.15-0.25 and variable x is 0.2-0.4;
- and
- wherein the photovoltaic device is configured to selectively convert light to electricity at wavelengths of 400-610 nm and below, while transmitting light at wavelengths of 620-700 nm.
