Description
Summary:The development of transparent solar cells extends the applications of photovoltaics by offering the opportunity to substitute the gigantic surface coverage of windows by solar panels to produce electricity. Herein, we report a new family of NIR‐sensitizers based on pyrrolopyrrole cyanine dyes, particularly efficient for the development of fully transparent and colorless dye‐sensitized solar cells since a record efficiency of 2.5 % was achieved with an average visible transmittance (AVT) of 76 % and a color rending index (CRI) of 93. Transparent photovoltaics is a disruptive technology which widens the deployment of photovoltaics into new sectors such as for windows beyond the classical use of opaque panels. The great potential of pyrrolopyrrole cyanine dyes as NIR‐sensitizers for the development of fully transparent and colorless dye sensitized solar cells is demonstrated.
