Abstract
This paper reports, the design, and modeling of a band gap matched, actively temperature controlled indoor photovoltaic optical system for solar spectral irradiance ranging from 350ânm to 870ânm (visible and part of near infrared) by employing Cadmium Sulfide/ Cadmium Telluride (CdS/CdTe) thin layer solar cell. In this case, an existing indoor daylighting system having 45.91% efficiency is remodeled to be a more an efficient light concentrating source with an improved light transmission efficiency of 51.65% for the proposed system. Under band gap matched conditions of the light spectrum and active temperature controlled environment, for a CdS/CdTe solar cell with 0.06%/mV as temperature coefficient, a 0.5% increase in cell efficiency and negation of â¼1.7% efficiency decay due to 12â°C temperature rise is theoretically predicted. A commercially available CdS/CdTe solar cell with 860.73âW/m2 as integrated input solar irradiance and of 0.085âm2area, an outdoor efficiency of 14.52% produces 10.62âW. The modeled system theoretically predicts â¼1.16 times more energy from the same system in addition to an extended life due to indoor conditions. Modeling and simulation of the proposed system are performed by using MATLAB V-9.2 and OptiSystem V-14.0 software showing a good agreement with theoretically predicted results.
