The fabricated organic solar cells based on PM6:BTP-eC9 blend provide relatively lower efficiency compared to those top values of the cells reported in literature. Further information and requests for resources and reagents should be directed to and will be fulfilled by the lead contact, Hai-Qiao Wang ([email protected])
Longi has revealed that 3 GW of M6 panels were ordered and delivered before the end of 2019. Next year, Longi’s total capacity of 23 GW of solar cells and 20 GW of modules will all be manufactured with M6 wafers, meaning that at least half of its output will be M6. Other companies are more aggressive about their predictions.
As it happens, Aiko Solar has done just this and has completed the modification of its 3.8 GW Tianjin factory to fulfill orders from customers for M6 cells. In addition, the company believes that shipments of M6 will account for more than 60% of its production in 2020, rising to 90% in 2021.
Wang Yuming, general manager of Jinchen Machinery – one of the largest PV manufacturing equipment providers in China – said at a recent industry conference that although the size of M6 almost reaches the limitations of some manufacturing equipment, the company’s solutions could be modified to switch to it at relatively little cost.
The solar cell with aqueous MoO x prepared by the aqueous sol–gel method showed almost comparable performance to the solar cell with the annealed an-MoO x HTL, even without high-temperature annealing, delivering a high PCE of over 17% in the PM6:Y6-based OPV cells.
The highest occupied molecular orbital (HOMO) and low unoccupied molecular orbital (LUMO) energy levels of Y6 were estimated to be at –5.65 eV and –4.10 eV, respectively. PM6 with deep-lying HOMO levels of –5.54 eV is preferred to obtained high Voc values in the NF OPV cells.
