Conductive film for heterojunction cells

Can indium-based transparent conductive oxide films be used in SHJ solar cells?

Learn more. Indium-based transparent conductive oxide (TCO) films are widely used in various photoelectric devices including silicon heterojunction (SHJ) solar cells. However, high cost of indium-based TCO films is not conducive to mass production of the SHJ solar cells.

Are indium-based TCO films conducive to mass production of SHJ solar cells?

However, high cost of indium-based TCO films is not conducive to mass production of the SHJ solar cells. A variety of indium-free or indium-less TCOs are explored and utilized presently. Here, SnO x films are deposited by reactive plasma deposition (RPD) with metal tin as the evaporation source.

Are crystalline silicon heterojunction solar cells transparent conductive?

Here, we report crystalline silicon heterojunction solar cells with reactive plasma deposition (RPD) grown ZnO:Ga 2 O 3 (GZO) at room temperature as a transparent conductive oxide (TCO) layer. Meanwhile, SHJ solar cells with magnetron sputtered indium tin oxide (ITO) transparent conductive layers are compared as reference.

Is TTO a viable alternative to indium-based conductive oxides for SHJ solar cells?

PV parameters of SHJ solar cells with indium-free transparent conductive oxides in the previous published work. TTO as an alternative to indium-based TCO material, must have better sustainability for future scale-up of indium-free SHJ solar cells. The host material SnO 2 of TTO is naturally abundant.

What is a silicon heterojunction solar cell?

A silicon heterojunction solar cell features uniquely indispensable transparent conducting oxide (TCO) layers integrating a low-temperature annealing metal paste. Its unique electrode requirement of optical, electrical, contact, and passivation properties is still the dominant factor to determine its rate of exposure mass manufacture.
