The data used is the US granted patent from 1976 until 2010, thus resulted of 1,100 patents data. The network of patent citation data is analysed based on the key network measure (i.e., number of nodes, density, in-degree centrality, and out-degree centrality) and followed by developing the network trajectory. The main path analysis is obtained by using both SPLC method (Search Path Link Count) and the SPNP method (Search Path Nodes Pair). The main path further is analyzed along with its sub-path to understand the evolution of c-Si PV technology. The results indicate that: 1) the c-Si Solar cells technology has very low network density which means the patents are sparsely connected with each other, 2) The connected patents are the representative of the ‘new’ thin-film solar technology, 3) The most cited patent is not a part the main trajectory, meaning that there is a low correlation between patent and technology development, 4) The US, Japan, and Germany are the main actors in c-Si solar cells technology. US and Germany are identified as key pioneers during the early stage of this technology, while Japan appears at later stages, 5) Siemens is the main actor in the initial c-Si PV technology.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Crystalline silicon (c-Si) PV technology,Network patent analysis,Technology development,Technology trajectory[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
