Fig. 6 corresponds to the section line A-A' of Fig. 5.
請參照圖5及圖6,太陽能電池20與前述之太陽能電池10類似,兩者主要的差異在於:太陽能電池20具有彼此斷開的多個PN接合(PN junction),而不一定要設置第一遮光件150及/或第二遮光件160,便能避免漏電現象產生。Please refer to FIGS. 5 and 6, the
具體而言,太陽能電池20包括多個第一型半導體圖案112、第二型半導體120、多個第一電極130及多個第二電極140。多個第一型半導體圖案112彼此分離。多個第一型半導體圖案112位於第二型半導體120上,以形成彼此斷開的多個PN接合(PN junction)。多個第一電極130分別位於多個第一型半導體圖案112上,且被第一間隙G1隔開,以各自與多個第一型半導體圖案112電性連接。多個第二電極140位於第二型半導體120上,分別對應多個第一電極130設置,且被第二間隙G2隔開,以各自與第二型半導體120電性連接。Specifically, the
舉例而言,在本實施例中,第二型半導體120可以是一個第二型半導體基板,多個第一型半導體圖案112可以是利用遮罩(mask)在所述第二型半導體基板中形成的多個第一型摻雜區,而多個第一型摻雜區(即多個第一型半導體圖案112)之間存在第二型半導體120的一部分122。然而,本發明不以此為限,根據其它實施例,也可利用其它適當方法形成彼此斷開的多個PN接合(PN junction)。For example, in this embodiment, the
值得一提的是,由於太陽能電池20的多個子電池U的多個PN接合係彼此斷開,因此多個子電池U能設置得更近,且不易出現嚴重的漏電現象。也就是說,在本實施例中,相鄰多個子電池U的多個第一電極130的距離(亦即,第一間隙G1的寬度d’)可進一步地縮減,例如寬度d’可小於或等於1公分。如此一來,便能更充分地利用半導體結構C的面積發電。此外,從實驗可知,當串聯的電壓越高(例如12伏特以上)時,漏電的問題會越明顯,而本發明採用PN接合彼此斷開的方法就可以有效解決,實現能提供高電壓且具有小體積的太陽能電池20。It is worth mentioning that, since the multiple PN junctions of the multiple sub-cells U of the

The solar cell includes a plurality of sub-cells connected in series with each other to provide a high voltage. Multiple sub-cells are formed using the same semiconductor structure.

一個第一電極、對應第一電極設置的一個第二電極、夾設於第一電極與第二電極之間的一個第一型半導體圖案及部分第二型半導體可形成一個子電池。太陽能電池包括彼此串聯的多個子電池,以提供高電壓。多個子電池係利用同一片半導體結構形成,因此,太陽能電池除了能提供高電壓,更具有體積小的優勢,利於設置或運用在各式電子裝置。更重要的是,由於太陽能電池的多個子電池的多個PN接合係彼此斷開,因此多個子電池能設置得更靠近,且不易出現嚴重的漏電現象。A first electrode, a second electrode provided corresponding to the first electrode, a first type semiconductor pattern and a portion of the second type semiconductor interposed between the first electrode and the second electrode may form a sub-cell. The solar cell includes a plurality of sub-cells connected in series with each other to provide a high voltage. Multiple sub-cells are formed using the same semiconductor structure. Therefore, in addition to providing high voltage, solar cells have the advantage of small size, which is advantageous for installation or use in various electronic devices. More importantly, since the multiple PN junctions of the multiple sub-cells of the solar cell are disconnected from each other, the multiple sub-cells can be placed closer together, and serious leakage phenomena are less likely to occur.
