摘要

The increasing demand for clean energy sources has driven the academic and industrialcommunities to dedicate large amounts of R&D budgets for finding an alternative energy source. Increasingpopulation and growing demands have strained ever-depleting fossil fuel sources. Moreover,the combustion of fossil fuel results in major greenhouse gasses such as carbon dioxide causing severeweather conditions such as global warming. Cultivation of solar energy using photovoltaics hasemerged as an efficient alternative clean energy source. Several materials have been investigated forsolar cell devices to obtain higher open-current voltage, fill factor and power conversion efficiencies.However, obtaining higher conversion efficiencies at lower cost remains a challenge. Hence, devicessuch as dye-sensitized solar cells (DSSCs) and bulk heterojunction (BHJ) have been studied. Graphene/graphene derivatives (graphene-metal oxides, graphene-polymers, graphite, graphene, dopedgraphene, graphene-carbon nanotubes hybrids, and quantum dots) have attracted increasing attentionbecause of their lightweight, easy and cost-effective processing, remarkable electrical, optical, andtunable band gap properties. Herein, we review recent advances in graphene/graphene derivatives inDSSC and BHJ solar cells. Role of graphene and its derivatives, when used as a photosensitizer,electrode, electrolytes, electron transport layer, a photoactive layer, and transparent electrode hasbeen discussed. The review indicates that utilization of graphene/graphene derivatives in photovoltaicapplications results in improved performance and opens new avenues for future applications.
