Selective emitter using a screen printed etch barrier in crystalline silicon solar cell

05-Oct-2012 | Kyuwan Song, Bonggi Kim, Hoongjoo Lee, Youn-Jung Lee, Cheolmin Park, Nagarajan Balaji, Minkyu Ju, Jaewoo Choi, Junsin Yi, Nanoscale Research Letters, 2012

The low level doping of a selective emitter by etch back is an easy and low cost process to obtain a better blue response from a solar cell. This work suggests that the contact resistance of the selective emitter can be controlled by wet etching with the commercial acid barrier paste that is ...

A solution-processable D–A–D small molecule based on isoindigo for organic solar cells

05-Sep-2012 | Miao Yang, Xuewen Chen, Yingping Zou, Chunyue Pan, Bo Liu, Hong Zhong, Journal of Materials Science, 2012

A new linear D–A–D organic small molecule (M1), with triphenylamine as electron donor (D) unit and isoindigo (ID) as electron acceptor (A) unit, was synthesized by Stille coupling reactions. It exhibits broad and strong absorption (300–700 nm), a relatively low HOMO energy level (−5.30 eV), low ...
