CIGS thin-film solar technology: Understanding the basics A brief history CIGS solar panel technology can trace its origin back to 1953 when Hahn made the first CuInSe 2 (CIS) thin-film solar cell, which was nominated
For example, today, a typical 6kW PV solar panel system costs approximately $18,000-$19,440 before the applicable federal tax credits and local incentives are applied. Before we break down residential PV solar system

Currently, there are approximately 0.7 GW of SHJ solar panels manufactured per year 99 and 40–50 GW of planned production capacity. 100 Alarmingly, if all such planned production capacity were to use ITO, this would consume 170–540 tonnes per year of indium, corresponding to 8.5–26.9% of 2019 global indium supply already.
Boosting this could greatly alleviate supply pressures. Projections indicate that indium production will reach its peak between 2025 and 2030, while the peak for photovoltaic solar panels due to indium shortages is anticipated around 2090, with an installed capacity of 1200 GW. Thus, the growth of photovoltaic capacity may lag behind actual demand.
For a 1 TW of production capacity using 20% of global indium supply, the indium consumption per cell must be reduced to below ∼0.38 mg W −1, which would only allow 3.7 nm or 9 nm thick ITO layers to be used in SHJ solar cells per side based on current usage reported by manufacturers or from theoretical calculations.
Ten of these photovoltaic technologies require indium, five of them require gallium in addition to indium, three of them require antimony in addition to indium, one technology requires tellurium in addition to indium, three of them require selenium in addition to indium and six of them demand silver in addition to indium.
Other commercial Si-based solar cells, such as Al-BSF, PERC, and TOPCon solar cells, have sufficient lateral conductivity from the doped silicon layers or bulk with boron or phosphorus as dopants such that ITO layers are not required. Hence, indium is of no concern for the mainstream PERC technology or emerging TOPCon solar cell technology.
A copper indium gallium selenide solar cell (or CIGS cell, sometimes CI (G)S or CIS cell) is a thin-film solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper indium gallium selenide solid solution on glass or plastic backing, along with electrodes on the front and back to collect current.
