全球PV（太陽光發電）的熱潮促使薄膜a-Si太陽電池產業在過去2∼3年內創下超過30%的大幅成長，未來更可望繼續成長。但原料p-Si（多孔質矽）不足及能源轉換效率低落成為擴大銷售的阻礙，目前PV的設備成本是其他可再生能源的3∼4倍、化石燃料的6∼10倍。可能解決該問題的是能將矽用量降至最少的利用薄膜a-Si、CdTe、CIS/CIGS、彈性薄膜技術的太陽電池，其生產活動主要由日本、台灣、歐洲負責。

第7章 結論
Abstract
The PV industry has shown more than 30% annual growth rate in the past two to
three years due to the global PV industry boom and shows a promising future.
However, it appears to have difficulties in rapid distributions due to
insufficient p-Si, a raw material, volume and low solar cell conversion
efficiency. The PV unit cost is 3 to 4 times more expensive than other
renewable energies and 6 to 10 times more expensive than fossil fuels.
In order to resolve such issues, solar cell makers focus in next-generation
solar cells such as thin film a-Si solar cells which minimize Si materials,
CdTe based solar cells, CIS/CIGS based solar cells, and flexible thin film
solar cells to cut the cell manufacturing cost. Of this, the thin film a-Si
solar cell technology is recognized as a research field to manufacture
inexpensive high efficiency solar cells to innovatively enhance the PV
economic efficiency by replacing expensive crystalline silicon solar cell.
Recently, there have been large-scale investments made in this field. It is
being produced in countries focused in Japan, Taiwan, and Europe.
Displaybank published "Thin Film a-Si Solar Cell Technology" regarding such
thin film a-Si solar cell technology. It analyzed the technology targeting
released and registered WIPS DB patents in Korea, Japan, Europe, and U.S. from
1977 to October 31, 2008 along with INPADOC and G-PAT patent database.
This report categorized the thin film a-Si solar cell technology basically by
major maker and applicant. The technology was divided into -RaSubstrate,
-RaTransparent Electrode, -RaMetal Electrode, -RaAbsorption Layer,
-RaInterlayer, -RaStructure, -RaLaser Scribing, -RaModule technology.
Specially, this report analyzed the key patent of thin film a-Si solar cell
manufacturing technology applied by major makers by yearly flow chart that it
allowed readers to understand major technologies' development trend and patent
rights at one glance.
