The low and high work function metals are necessary for the effective injection of electrons and holes, respectively. Here, we introduce a fully novel design concept using organic semiconductor heterojunctions (OSHJs) as the charge injectors for achieving highly efficient OLEDs, regardless of the work functions of the electrodes.
Gettering is proved effective on above 26% efficiency Si solar cells Heterojunction formed at the amorphous/crystalline silicon (a-Si:H/c-Si) interface exhibits distinctive electronic characteristics for application in silicon heterojunction (SHJ) solar cells.
Heterojunction formed at the amorphous/crystalline silicon (a-Si:H/c-Si) interface exhibits distinctive electronic characteristics for application in silicon heterojunction (SHJ) solar cells. The incorporation of an ultrathin intrinsic a-Si:H passivation layer enables very high open-circuit voltage (Voc) of 750 mV.
Silicon heterojunction (SHJ) solar cells have achieved a record efficiency of 26.81% in a front/back-contacted (FBC) configuration. Moreover, thanks to their advantageous high VOC and good infrared response, SHJ solar cells can be further combined with wide bandgap perovskite cells forming tandem devices to enable efficiencies well above 33%.
Silicon heterojunction devices rely on the use of thin‐film silicon coatings on either side of the wafer to provide surface passivation and charge carrier‐selectivity. Beyond traditional indium tin oxide, multiple higher‐mobility indium‐based transparent conductive oxides have been employed successfully in HJT cells.
In 2017, Kaneka Corporation in Japan realized heterojunction back contact (HBC) solar cell with an efficiency of up to 26.7% (JSC of 42.5 mA·cm −2) 25, 26, and recently, LONGi Corporation in China has announced a new record efficiency of 27.30% 16.
In this study, we produced highly efficient heterojunction back contact solar cells with a certified efficiency of 27.09% using a laser patterning technique.
