6 FAQs about [The role of aluminum-zinc plating on photovoltaic panel brackets]
Is aluminum-doped zinc oxide a transparent electrode material?
As a promising transparent electrode material, aluminum-doped zinc oxide (AZO) possesses comparable transmittance and conductivity and is environment-friendly and low-cost. Herein, we report the fabrication of perovskite solar cells using AZO as the transparent electrodes.
What is aluminum-doped zinc oxide (AZO)?
Aluminum-doped zinc oxide (AZO) is one of the most popular transparent conducting oxide layers that can be employed in many optoelectronic applications in particular in photovoltaic devices due to being a low-cost and nontoxic material.
How does a zinc atom affect ohmic losses?
One free valence electron is produced when one zinc atom is replaced by the aluminum atom, and thus, 1 atomic % aluminum atoms create a large number of free electrons in the Al-doped ZnO films, and thus, the resistivity decreases. The improvement of the conductivity reduces the device’s ohmic losses.
How azo films are used in fabricated solar cells?
The AZO films utilized in the fabricated solar cells were with prepared under optimized 10 mTorr deposition pressure at room temperature and 150 °C temperature. Hence, using such parameters revealed that applying substrate temperature increased the cell efficiency from 7.3% to 8.0%.
What is the active area of a photovoltaic device?
