“…To further optimize the PCE and AVT, the antireflective coating (ARC) layer was introduced to enhance the AVT of the ST-OSCs. Here, the MoO 3 layer was employed to reduce the reflection at the Ag side. − Taking into account the aforementioned results, the device with a D/A ratio of 0.7:1.2 was selected as the control one, and a series of ST-OSCs were fabricated using the normal structure of ITO/PEDOT:PSS/PM6:L8-BO/PDINN/Au(1 nm)/Ag (15 nm)/MoO 3 (35 nm). The transmittance spectra of the used electrode are displayed in Figure S5.…”

Semitransparent organic solar cells (ST-OSCs) have garnered significantly more attention in recent years due to their enormous potential commercial value in various fields, including building-integrated photovoltaics (BIPVs), transportation, electronic equipment, and agriculture. However, the equilibrium between power conversion efficiency (PCE) and average visible transmittance (AVT) is a key factor hindering the further development of ST-OSCs.Here, PM6 and LB-BO were elaborately selected as the donor and acceptor, respectively, for preparation of ST-OSCs. Through the modulation of the donor-toacceptor (D/A) ratio, transparency was effectively enhanced without seriously affecting the photovoltaic performances of the devices. The optimized device achieved a PCE of 12.30% and an AVT of 20.63% with a D/A ratio of 0.7:1.2, while light utilization efficiency (LUE) reached 2.54%. To further improve the LUE, the MoO 3 layer was introduced as an antireflective coating, resulting in a PCE of 10.62% and an AVT of 24.63%, thereby yielding an LUE of 2.62%. This strategy offers an efficient, straightforward, and cost-effective method to simultaneously enhance the PCE and AVT of ST-OSCs.

A tetracyclic-bislactone-based copolymer donor for efficient semitransparent organic photovoltaics

Abstract: A copolymer donor PBDTTPTP based on a tetracyclic bislactone unit, thieno[2',3':5,6]pyrano[3,4-d]thieno[3,2-b]pyran-4,9-dione (TPTP), was developed. The single crystal structure of a TPTP derivative indicates the π-extended planar geometry of TPTP and...
