에너지 기술 R&D사업은 그 성과에도 불구하고 수요에 기반한 기획 측면이나 사업화에 있어 성과가 저조한 것으로 평가받아 왔으며, 특히 사업화 추진에 있어 시급한 과제로 '기술 수용성'(Acceptance) 향상이라는 지적이 제기되곤 하였다. 이에 산업통상자원부는 사용자가 R&D 기획, 개발, 검증 과정에 참여하여 사업의 이해도를 높이고 수용성을 제고하는 '에너지기술 수용성 제고 및 사업화 촉진사업'을 2016년부터 추진하고 있다. 그런데, 사회문제해결형 R&D라 부를 수 있는 본 사업은 산업통상자원부의 기존 에너지기술 R&D와는 성격이 다른 새로운 R&D의 모습을 갖는다고 할 수 있으며 그에 따라 그 시행과정에서 사용자, 이해당사자들이 참여하는 등 연구자들은 예전과는 다른 여러 가지 새로운 방법론의 수행을 요구 받고 있다. 본 연구에서는 해당 사업의 기획 및 실행에 참여한 경험을 토대로 성과멘토링, 성과공유 워크숍, 성과지표의 개발, 운영관리방안 등을 통해 '에너지기술 수용성 제고 및 사업화 촉진사업'의 특성 및 향후 개선방안을 논의하고 사회문제해결형 R&D사업에의 발전방안을 제안하고자 한다.

The adequate measurement of government expenditure efficiency for Energy Technology Development is a difficult empirical issue and the literature on it, particularly when it comes to aggregate and international data. Contribution in this study is threefold: first this study analyze the adequate measurement of government expenditure efficiency on Energy Technology sector of 24 OECD countries and korea. Second this study reconstruct efficiency composite indicators, named "Energy Technology Development Interest level indicator". Third this study assesses the efficiency of government expenditure for Energy Technology Development. The results can be summarized as follow: Korea's government expenditure efficiency for Energy Technology Development is highly ranked among 25 OECD countries based on Energy Technology Development R&D Budgets and Energy Technology Development R&D Budgets per thousand units of GDP indicators. However, Korea's ranking has fallen to 20th. The assessment suggests that government will be have to provide more government expenditure to enhance the efficiency on Energy.

There are many eutrophic lakes by point and non-point pollution sources such as in dustrial waste water, domestic raw sewage, and mucks. The eutrophic lakes not only cause algal blooms but also destroy the ecosystem in the lakes due to high nutrient concentrations. The purpose of this study was to improve water quality in eutrophic lakes by cultivating microalgae using photobioreactors (PBRs) with selectively permeable mesh (SPM), supplying nutrients in the lake and inhibiting cell leakage by diffusion and water permeability. Chlorella vulgaris, was cultivated using PBRs with SPM installed in Inkyung Lake located in Inha university, Incheon, Korea. When cultivating C. vulgaris, $8.3g/m^2/day$ of average biomass productivity was obtained at 3 days. Furthermore, concentrations of total nitrogen and phosphorus were reduced by 35.7% and 84.2%, respectively, compared to initial condition and water quality in eutrophic lake was improved to oligotrophic environment. These results suggest that microalgal cultivation using PBRs with SPM in the lake could produce microalgal biomass as well as improve water quality by decreasing nutrient concentrations.

A portfolio matrix analysis was conducted to improve R&D productivity of the government-funded R&D projects in the energy sector. 27 projects (42 detailed technologies) in 2018 were evaluated on a 5-point scale in terms of availability and technology competitiveness, and portfolio matrix analysis was conducted twice. The results of the portfolio matrix analysis could provide the landscape of on-going R&D projects at a time and could be utilized as feedback data to establish development strategies for individual projects, while establishing differentiated management directions to improve R&D productivity in each of the four areas of the portfolio matrix.

Waste reduce, recycle, energy recovery technology is one of 27 key green technology by 2012, the government should increase R&D investment, despite the period 2008 to 2010 average annual growth rate was decreased. Accordingly, this area of government investment in R&D status analyzed in detail and as a result, total government investment in R&D decreased, but in these fields to define strategic product services investment in technology is increasing centralization trend that appears to be investment in the quality of determined that the good is. In particular, in 2010, strategic product service of the technologies 3 technology groups ((1) waste energy equipment (2) waste resource recycling facilities (3) waste based materials production facilities) the proportion of 24-28% relatively evenly invested, government R&D is judged that adequate investment in quality.

This paper studies examines the R&D efficiency in Korean energy industry by making multiple logistic regression of the product technological level with firms' endogenous technological efforts and cooperations for R&D between upstream and downstream firms. The technological level of Korean energy industry is analyzed to have been positively influenced by economy of scale effect and cooperations for R&D between upstream and downstream firms, but negatively impacted by firm size, and not impacted by competitive market structure, R&D investment, and R&D manpowers. The implications of this study are as follows: i) to heighten the technological level, domestic market would be transformed to be more competitive; ii) Korean Energy industry should make efforts intensifying R&D-related manpowers and investments; iii) although the firm size is analyzed to have negative impact on technological level, firms, lager or smaller, must be supported to accumulate technological capabilities; iv) R&D-cooperating efforts between upstream and downstream firms on the value-chain should be supported.

This study analyzes the technological level of Korean waste-to-energy(WTE) firms and its determinants by using a multiple logistic regression analysis based on a survey. As the results of analysis, the technological level of Korean WTE firms has been positively influenced by the firm size, R&D expenditures, R&D manpower, but negatively influenced by the competition in domestic market. Also there is no significant effect of the economy of scale. The policy implications of this study are as follows; First, the system in which stakeholders coevolve should be set up to prevent excessive market competition from having a bad effect on the technological level of Korean WTE firms. Second, it is needed to make an effort to achieve the economy of scale by increasing an output and decreasing cost in WTE firms.

One of the current innovation trends in the solar industry is the increase in the size of silicon wafers. As the wafer size increases, the series resistance of the module rises, highlighting the need for research on methods for cutting and bonding solar cells. Among these, the Infrared (IR) laser scribing technique has been extensively researched. However, there is still insufficient optimization research regarding the thermal damage caused by lasers on the Transparent Conductive Oxide (TCO) layer of Heterojunction (HJT) solar cells. Therefore, in this study, we systematically varied conditions such as IR laser scribing speed, frequency, power, and the number of scribes to investigate their impact on the performance of cut cells under each condition. Additionally, we conducted a comparative analysis of thermal damage effects on the TCO layer based on varying scribing depths.

The aim of this study were to investigate the process of national R&D project planning by using the industry quantitative analysis(especially supply-chain enterprise ananlysis). In the selection process of funding project, the role and significance of the industry analysis can be identified as the effective guideline of using this methodology. Across the study, the following is noted : the factors of R&D effectiveness and R&D necessity are found reliable and valid. On the other hand, the emptiness of supply chain and the positive effect of foreign trade balance did not influence the selection of project. The information gained from this study will help us to define better expectations and industry analysis employing to the National R&D Project Planning.

Transparent photovoltaics (PV) are used in various applications such as building-integrated photovoltaics (BIPV). However, crystalline silicon (c-Si) is not used for developing transparent PV due to its opaque nature. Here. we fabficate the three holes in 6-inch c-Si solar cells using laser scribing process with an opening area ratio of about 6.8% for transparent c-Si solar modules. Moreover, we make the shingled strings using the perforated cells. Our 7 interconnected shingled string PV cells with 21 holes show a solar to power conversion of 5.721 W. In next work, we will fabricate a transparent c-Si PV module with perforated strings.
