What Renshuo Solar does

Renshuo Solar (仁烁光能) is a Suzhou-headquartered, privately held perovskite photovoltaic manufacturer founded in December 2021 by Nanjing University professor Tan Hairen. The company develops single-junction perovskite, all-perovskite tandem, perovskite/silicon tandem, and flexible perovskite modules built around a proprietary solution-based, low-temperature coating and crystallization process. Its technology stack has set 11 consecutive world records for perovskite cell efficiency, with a 30.1% tandem cell R&D efficiency, 26.12% large-area tandem module efficiency, and a 26.2% all-perovskite tandem module certified by Japan's JET. The company holds 120+ core patents and operates a wholly-owned research subsidiary, the Jiangsu Perovskite Industry Technology Research Institute, jointly with Nanjing University.

Renshuo sells perovskite modules and turnkey production-line technology services through direct enterprise sales. Its commercial portfolio spans the Shuodan/Shuojin standard and large-format modules, the Shuocai/Shuoguang/Shuoneng BIPV family (colorful, transparent, and large-size building-integrated variants), and the Shuorou flexible module for curved surfaces and vehicle rooftops. End-use segments include centralized solar plants, commercial and industrial rooftops, building-integrated photovoltaics (BIPV), and new energy vehicles, with active discussions underway with multiple unnamed NEV manufacturers for vehicle rooftop integration. Production has scaled from a 10MW R&D pilot line in 2022 to a 150MW commercial line at end-2023, with a GW-scale line now under construction; current commercial modules carry NREL, TÜV IEC, CQC, JP-AC, and UL61730 certifications.

The business model combines hardware module sales at per-watt pricing (currently ~1.2 CNY/W on the 0.72m² single-junction SKU, with a stated GW-scale target below 0.65 CNY/W) with professional services revenue from turnkey production-line technology transfer packages, exemplified by a 100MW+ project delivered for a National Traditional Energy Group subsidiary in Shandong. Customer logos are concentrated in domestic state-owned energy groups, building and architectural partners (Shanghai Yaopi Glass, Tusdesign, Suzhou Kelida), and certification bodies (Chengdu Product Quality Inspection and Research Institute). Two undisclosed funding rounds (2022 Series A led by MultiGo Capital with CAS Star, Yunqi Partners, K2VC, SND Ventures, GP Hi-Tech, China Industrial Fund; January 2024 round with Addor Capital, Changshu Economic Development Holdings, Hengtong, Jianyu Group, Oriental Fortune Capital, Sealand Securities, Everstate Capital, Zhejiang Zhong Ying Holding, Zhongke Advanced Fund, and Zhongtian Huifu) have funded capacity expansion and R&D.
