Abstract: Semitransparent organic solar cells (ST-OSCs) exhibit highly promising applications to develop integrated photovoltaics and power-generating windows. However, the development of ST-OSCs is significantly lagging behind opaque OSCs, especially for all small molecules ST-OSCs. Here, four unique squaraines dyes (IDPSQ, SQ-BP, D-BDT-SQ, and AzUSQ) were successfully used as donors in ST-OSCs, whose colors can be tuned from purple to blue, green, and dark green, respectively. While using ultrathin Ag as a transparent electrode, the ST-OSCs fabricated using IDPSQ:PC71BM, SQ-BP:PC71BM, D-BDT-SQ:PC71BM, and AzUSQ:PC71BM yield power conversion efficiencies (PCEs) of 2.96%, 4.36%, 4.91%, and 1.71%, respectively, and their colors are purple, cyan, brown, and light brown, respectively. Compared with their opaque OSCs (PCEs of 3.95%, 5.45%, 5.84%, and 1.91%, respectively), the reduction in the PCEs are as low as 25%, 20%, 16%, and 10%, respectively. Furthermore, each of these ST-OSCs exhibit good average visible transmittance (AVT) of 25%–30%, favorable CIE color coordinates, and a color rendering index (CRI) of 71%–97%. Finally, by changing the thickness of the Ag electrode, an impressive PCE of 4.9% along with an AVT of 25% and a CRI of 97% can be obtained in D-BDT-SQ:PC71BM-based ST-OSCs, which is the highest PCE among all small molecules ST-OSCs.
