Abstract:
The present invention relates to a thin condensing photovoltaic module, and more specifically, it is about a thin condensing photovoltaic module that can significantly reduce the thickness of the module in which in order to do so, primary optical elements are combined with each other to form an array so that it may produce the overall thickness of the module to be very thin. The thin condensing photovoltaic according to the present invention comprises a base plate, a carrier that is equipped with a solar cell, a primary optical element array that is disposed on the upper part of the base plate and forms an array of primary optical elements that condense the light primarily, a carrier frame that is installed on the upper part of the base plate and has a plurality of carriers with predetermined intervals, and a second primary optical element that is equipped on the upper part of the solar cell and may condense the light collected from the first primary optical element to the solar cell secondarily. The first primary optical element may include a lens unit that condenses the light to the second primary optical element primarily and a side surface that is connected to the first primary optical element that is adjacent to the edge of the lens unit which extends downwardly.
Abstract:
The present invention relates to a light-concentrating solar cell module and, more specifically, to a light-concentrating solar cell module which enables multiple primary optical components to be combined together and form an array; can reduce the overall volume by reducing the thickness of the solar cell module; and can maximize the efficiency of a solar cell by reducing an incident angle to the solar cell. The light-concentrating solar cell module according to the present invention includes the following components: a base plate; multiple receivers which are equipped with a solar cell, and prepared on the base plate at predetermined intervals; a primary optical component array in which multiple primary optical components, which primarily concentrate incident light, are combined together and form an array; and a secondary optical component which secondarily concentrates the light, which was primarily concentrated by the primary optical components, on the solar cell. The primary optical component comprises the following parts: a lens part which primarily concentrates incident light on the secondary optical component; and a side part which is extended downward from the edge of the lens part and fixed to the base plate.
Abstract:
PURPOSE: A condensing type solar cell module is provided to improve the efficiency of a solar cell by inputting light of a first optical component to a lateral side of a second optical component. CONSTITUTION: A first optical component(20) firstly condenses incident light. A second optical component(30) secondly condenses the incident light. A central part(21) condenses the light which is inputted to the first optical component. The light is inputted from the central part to a peripheral part(22). The second optical component includes an upper side and a lateral side.
Abstract:
PURPOSE: A concentrating photovoltaic power generating device is provided to uniformly distribute sunlight inputted to a solar cell by increasing the number of total reflection of incident sunlight from a primary optical element. CONSTITUTION: A primary optical element(12) primarily concentrates sunlight. A solar cell(14) converts solar energy into electric energy. A secondary lens(20) is located between the primary optical element and the solar cell and includes an input surface(21), a lateral side(22), and an output surface(23) which is narrower than the input surface. A total reflection angle correcting unit(30) is formed on a secondary lens to have one or more total reflection surfaces.
