Planar‐type concentrating photovoltaics with cylindrical lenses directly integrated with thin flexible GaAs solar cells

Concentrated photovoltaics allow a reduction of expensive semiconductor materials by collecting incident light through optical elements such as lenses and/or mirrors, which usually require bulky or heavy dual‐axis solar trackers, requiring dedicated installation sites. In this paper, we report a pla...

Description
Summary:Concentrated photovoltaics allow a reduction of expensive semiconductor materials by collecting incident light through optical elements such as lenses and/or mirrors, which usually require bulky or heavy dual‐axis solar trackers, requiring dedicated installation sites. In this paper, we report a planar‐type concentrating photovoltaics with cylindrical lenses on which flexible GaAs solar cells are directly integrated on the curvilinear surfaces. The planar‐type concentrating system maintains both a focused beam width and angle invariably onto its integrated solar cells throughout the day. Computational and experimental studies at various incident angles prove the benefits of the design. Demonstrations of a custom‐built cylindrical lens solar tracker installed on a rooftop or sidewall of a building prove the feasibility of the proposed concept. Planar‐type concentrating photovoltaics with cylindrical lenses on which flexible GaAs solar cells are directly integrated on the curvilinear surfaces. Minimal single‐axis rotational motion of the combined lenses and solar cells maintains focused incident light onto the integrated solar cells throughout the day.
