成果简介	NOVELTY - Dual solar cell albedometer (100), comprises: at least two solar cells (106A, 106B) adapted to be arranged to face away from each other; at least two transparent members (102A, 102B), where each of the transparent member is adapted to facilitate daylight radiation to reach respective the solar cell; many encapsulant members (104A, 104B, 104C) adapted to form bonds with the solar cells and the transparent members thus binding the solar cells to the transparent members; and a frame structure (110) adapted to house the solar cells, the transparent members and the encapsulant members, where the solar cell are thermally connected with another solar cell through respective encapsulant member. USE - The albedometer is useful for measuring albedo i.e. the ratio of the radiation reflected from a surface to the global radiation received from the sunlight, which is used for determining an appropriate location for the installation of e.g. photovoltaic modules. ADVANTAGE - The albedometer: accurately measures the albedo values and eliminates the error in the measured albedo value due to less temperature difference between the solar cells; has solar cell i.e. thermally connected with another solar cell so that both solar cells of the albedometer will have the near identical temperature thus eliminating the error arising from temperature mismatches of the solar cells while measuring albedo values, and enabling both solar cells to have near identical degradation rates which in turn reduces the error caused by different degradation rates of the solar cells; utilizes two solar cells having identical dimensions and technology, with matched electrical specifications thus eliminating the error caused by spectral mismatches of the solar cells while measuring albedo values; is a compact and lightweight dual solar cell albedometer which eliminates the usage of mounting structure and back sheets in the dual solar cell albedometer; is reliable and is inexpensive and is easy to manufacture; has solar cell each of which is a silicon solar cell which aligns with the spectral response of the photovoltaic modules thus ensuring precise determination of the albedo value; and minimizes the difference in temperature between the solar cells thus eliminating the error in the measured albedo value due to minimal temperature difference. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing a dual solar cell albedometer comprising cutting a full-size solar cell into at least two solar cells of predetermined identical dimensions and electrical specifications by a laser cutting process, measuring current-voltage characteristics of each solar cell, soldering a pair of electrical terminals on each solar cell, arranging alternatively the solar cells and the encapsulation members in a layer-by-layer pattern and sandwiched between a pair of transparent members, performing laminating process for the encapsulant members thus binding the solar cells to the transparent members, sealing the solar cells and the encapsulant members by a sealing member, thus restricting fluid entry into the solar cells and the encapsulant members, housing, by a frame structure, the solar cells and the transparent members in its to facilitate packaging of the dual solar cell albedometer, and measuring the current-voltage characteristics of each solar cell after packaging the albedometer for recalibration of the solar cells. DESCRIPTION OF DRAWING(S) - The figure illustrates a sectional view of the dual solar cell albedometer. 100Dual solar cell albedometer 102A, 102BTransparent members 104A, 104B, 104CEncapsulant members 106A, 106BSolar cells 110Frame structure
