Maturity:

Copper-Indium-Selenide (CIS) and Copper-Indium-Gallium-Diselenide (CIGS) PV cells offer the highest efficiencies of all thin-film PV technologies.

Benefits:

Energy saving: approx. 16 TJ/yr (LHV)
CO2 reduction: approx. 880 tCO2/yr
(total 1MW power plant(e.g. 100 sites of 10kW PV), 20% of capacity factor)
(compared to single gas turbine)

Co-benefits:

Reduction of air pollutants (e.g. NOx, SOx, dust (if compared to fuel-fired power plant))
Reduction of thermal effluent
Installing electricity for off-grid region

Differentiators:

Thin-film solar cells (just 2 to 3 μm thick) require substantially less semiconductor material to manufacture in order to absorb the same amount of sunlight.
High efficiency up to 14.6%, and continuing R&D for target efficiency (20%@2017, 25%@2025)

Succes factors and requirements:

Environmental regulation (e.g. air pollutants)

Investments required:

0.8USD/Wp
(Global average c-Si module selling price, source: RENEWABLE POWER GENERATION COSTS IN 2014, IRENA)

Timeframe:

Under consideration
