The present invention provides a translucent solar cell and a manufacturing method thereof. The translucent solar cell comprises, in stacking order, a substrate, a first electrode layer, a photoconductive layer and a second electrode layer. The translucent solar cell is characterized in that there are formed a plurality of first light-transmissive apertures on the second electrode layer and the plurality of first light-transmissive apertures are further extended in a depth direction to the photoconductive layer to form a plurality of second light-transmissive apertures corresponding to the first light-transmissive apertures. A projected area of each of the second light-transmissive apertures is equal to or smaller than that of a corresponding first light-transmissive aperture.

Translucent solar cell and manufacturing method thereof

Disclosed are a thin film solar cell module and a manufacturing method thereof. The thin film solar cell comprises, from bottom to top, a first substrate, a first electrode, an absorber layer, and a second electrode layer. A current output region with a current output element disposed therein is formed at the thin film solar cell module. The absorber layer in the current output region is removed through a mask, thereby making the first electrode layer contacts directly there with the second electrode layer. The current output region can be formed at the positive electrode, the negative electrode, or both positive electrode and negative electrode simultaneously, of the thin film solar cell module, thereby increasing the contact area between the first electrode layer and the second electrode layer at the positive electrode and the negative electrode. The useless current, the resistance and the heat generated there are reduced.

Thin-film solar cell module and a manufacturing method thereof

Disclosed are a stacked-layered thin film solar cell and a manufacturing method thereof. The stacked-layered thin film solar cell includes plural unit cells connected together electrically, each including a substrate, a first electrode layer, a first photoconductive layer, an interlayer, a second photoconductive layer and a second electrode layer, wherein the first electrode layer is divided by plural first grooves; plural second grooves are formed through the second photoconductive layer, the interlayer, and the first photoconductive layer; and plural third grooves are formed in the second electrode layer and extended downward through the first photoconductive layer. The first, second and third grooves are offset with respect to one another. The stacked-layered thin film solar cell is characterized by plural recesses formed at intersections between the interlayer and the second grooves for preventing leakage of electrical current from the first or second photoconductive layer to the interlayer through the second grooves.

Stacked-layered thin film solar cell and manufacturing method thereof

A stacked-layered thin film solar cell has a plurality of independent unit cells comprising a substrate, a first electrode layer, a first photoconductive layer, an interlayer, a second photoconductive layer, and a second electrode layer in a series stacked structure, wherein at least one first separation groove is formed within the first electrode layer and the stacked-layered thin film solar cell is characterized in: at least one second separation groove formed on the interlayer, at least one connection groove passing through the first photoconductive layer and the second photoconductive layer, and at least one third separation groove extending downward at a periphery of each of the unit cells so that the connection grooves and the third separation groove are concurrently located inside a projection zone of the second separation groove.

The present invention provides a stacked-layered thin film solar cell and manufacturing method thereof The manufacturing method includes the steps of: providing a substrate, a first electrode layer and a first light-absorbing layer; providing a mask with a plurality of patterns above the first light-absorbing layer; forming an interlayer made of an opaque, highly reflective material by providing the mask on the first light-absorbing layer, wherein the interlayer has a plurality of light transmissive regions corresponding to the patterns, and the light transmissive regions are provided to divide the interlayer into a plurality of units; and then depositing a second light-absorbing layer on the units and a second electrode layer on the second light-absorbing layer.

Thin film solar cell and manufacturing method thereof

A translucent solar cell and a manufacturing method thereof are provided. The translucent solar cell at least includes a substrate, a front electrode layer, a photoconductive layer, and a back electrode layer stacked in order. Therein, a plurality of apertures are formed on the front electrode layer. In addition, a plurality of light-transmissive regions are formed on the back electrode layer and further extended in a depth direction so as to reach the plurality of apertures on the front electrode layer. Thus, the projected area of each light-transmissive region is within and smaller than that of the corresponding aperture.
