Customer ServiceThin film solar cells are favorable because of their minimum material usage and rising efficiencies. The three major thin film solar cell technologies include amorphous silicon (α-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe).
Thin film solar cells are one of the important candidates utilized to reduce the cost of photovoltaic production by minimizing the usage of active materials. However, low light absorption due to low absorption coefficient and/or insufficient active layer thickness can limit the performance of thin film solar cells.
In 1981, Mickelsen and Chen demonstrated a 9.4% efficient thin-film CuInSe2/CdS solar cell. The efficiency improvement was due to the difference in the method of evaporating the two selenide layers. The films were deposited with fixed In and Se deposition rates, and the Cu rate was adjusted to achieve the desired composition and resistivity.
Such micron-scale features are not beneficial for thin film solar cells in which the active absorber layer is just a couple of microns or even several hundred nanometers in thicknesses. In addition, micron-scale features require deep etching and are known to introduce defects in the material .
CIGS and CdTe hold the greatest promise for the future of thin film. Longevity, reliability, consumer confidence and greater investments must be established before thin film solar cells are explored on building integrated photovoltaic systems. 1. Introduction
