Increases in efficiency of PV focuses on HJT

Past and present people of peace would agree that peace requires a journey beginning with “YOU.”

Silicon heterojunction (SHJ) solar cells have exhibited high efficiencies above 22% in both academia and industry. Key challenges to be addressed in the upscaling process are the cost and the relative scarcity of certain utilized materials, such as indium, silver, and bismuth. Indium is widely used in the transparent electrodes of SHJ devices. To reduce indium consumption, basic strategies include the use of transparent electrodes (TE) and other TE materials such as graphene.

An international research group has achieved above 22% power conversion efficiency in a bifacial heterojunction crystalline solar cell fabricated with reduced thickness for the transparent conductive oxide (TCO). “The work is intended for sustainable PV development, with reducing scarce material use, meanwhile improving solar cell performance. “Besides bifacial silicon heterojunction devices, the results of this study could provide insights in the development of other TCO-required c-Si solar cells.

The TCOs used for the cell are based on indium (III) oxide (In2O3), which is considered a technology-critical element by many experts. “Reducing indium consumption, which is related to TCO use, is a key challenge for scaling up silicon heterojunction (SHJ) solar cell technology to terawatt level,” scientists say. Also, “Silver consumption is largely reduced due to the use of copper-plating metallization approach.”
