An object of the present utility model improves photoelectric conversion efficiency.

Because this equipment is in order to double absorption sunlight, therefore not only need high performance solar cell material but also will ensure to reduce again the probability of secondary reflection.In addition due to the particularity of the curve form of this design, the solar cell material selected by requirement has certain pliability.Select curve flexibility solar cell.

In order to complete the double absorption to solar energy, designing and calculating must being carried out to solar absorption curved surface and each parameter of shaft-like photovoltaic converter, making overall efficiency high as far as possible when saving material as far as possible.

The selection of solar cell material: the factor such as integrated cost and efficiency, we have selected CIGS thin film solar cell material.

The design of solar absorption curved surface: spread out to make the solar energy after reflection, no longer be gathered on a point, by researching and analysing, through changing paraboloidal shape, having simulated a kind of new curved surface makes the solar energy after reflection through the integrated wire of this curved surface post-concentration, then design a shaft-like photoelectric conversion device at its rotary shaft position, just can have devised novel solar power plant.

When l value is determined, when the sunlight that curved surface device reflects all is absorbed by rod-like device, now the long h of bar has maximum.

When

0 < θ < \frac{π}{4}

Time, as shown in Figure 7,

h = l \cdot c o s θ - l \cdot s i n θ \cdot t a n (\frac{π}{2} - 2 θ) .

When

θ = \frac{π}{4}

Time, as shown in Figure 8,

h = l \cdot c o s θ = \frac{\sqrt{2}}{2} l .
