One of the distinctive features of organic solar cells is the ability to selectively absorb light within specific wavelength ranges. For that reason, they can be designed to mainly absorb light outside the visible spectrum, while simultaneously transmitting visible wavelengths. This ability makes them a perfect fit for semi-transparent applications such as tinted windows and agrivoltaics.\\ In agrivoltaic applications, it is important to reach a sufficient transparency level, in order to minimize negative effects on plant growth. This transparency can be quantified by the growth factor, which represents the weighted percentage of light transmitted through the cell, based on the wavelengths that are most relevant for plant growth.
