Utilization of diverse semiconductor materials in solar cells impacts their ability to generate electricity in low-light environments. Traditional silicon-based solar cells dominate the market; however, materials such as cadmium telluride (CdTe) and copper indium gallium selenide (CIGS) are gaining prominence due to their favorable low-light performance characteristics. CdTe and CIGS cells can maintain adequate efficiency levels even when the intensity of incoming light is reduced.

Technological advancements also play a dual role in enhancing performance metrics. Recent innovations involve improved light trapping mechanisms and anti-reflective coatings that maximize photon absorption under variable conditions. Multi-junction solar cells, which consist of multiple layers of semiconductor materials, can capture a broader spectrum of light. This feature allows for efficient functioning, particularly in conditions of limited illumination.

b. ANGLE AND ORIENTATION OF INSTALLATION

Proper installation remains a paramount consideration for solar energy systems. The orientation and tilt of solar panels significantly influence energy absorption. Adjusting panels to designated angles ensures they capture the maximum amount of diffuse sunlight available during cloudy days or in shaded areas.

Moreover, implementing tracking systems can substantially enhance performance by allowing panels to follow the sun’s trajectory throughout the day. Positioning solar cells in optimal locations and ensuring no physical obstructions overshadow them can profoundly impact their output, especially in low-light situations. By analyzing sun paths and environmental factors like trees or buildings, homeowners and installers can take steps to maximize sunlight exposure.
