Silicon heterojunction (SHJ) solar cells are recognized as one of the most efficient architectures in silicon-based photovoltaic devices. However, the reliance on indium (In)-based transparent conductive oxides (TCO) is anticipated to constrain their production capacity due to the critical and economically volatile nature of In.
This poses a significant hurdle to the future expansion of heterojunction solar cell industry. Although reduced-indium SHJ solar cells have reached an efficiency of 25.94 % [15], further research is urgently needed for efficient indium-free SHJ solar cells in …

Indium Tin Oxide (ITO) is a key material used in solar cells. Solar cells are devices that turn sunlight into electricity, and ITO helps make them work better. It is both transparent and conductive, meaning it allows light to pass through while also carrying an electric current.
To avoid the use of indium, basic strategies include: (a) developing TCO-free SHJ solar cells; (b) using indium-free TCO materials such as aluminum-doped zinc oxide (AZO) [16], [17], which has attracted much attention.Although the concept of TCO-free SHJ solar cells has been demonstrated, development has been hindered by contact and passivation issues [18].

Solar cells are made of semiconductor material, typically silicon in crystalline solar cells. Traditionally, a solar cell has two layers: an n-type with a high concentration of electrons and a p-type with a relatively low concentration of electrons. When sunlight hits the n-type layer, electrons flow from that section to the second and create an electrical current that …
